Opis:
The paper refers to the main problem connected with biomass gasification - a presence of tar in a product gas. This paper presents preliminary results of tar decomposition in a microwave plasma reactor. It gives a basic insight into the construction and work of the plasma reactor. During the experiment, researches were carried out on toluene as a tar surrogate. As a carrier gas for toluene and as a plasma agent, nitrogen was used. Flow rates of the gases and the microwave generator’s power were constant during the whole experiment. Results of the experiment showed that the decomposition process of toluene was effective because the decomposition efficiency attained above 95%. The main products of tar decomposition were light hydrocarbons and soot. The article also gives plans for further research in a matter of tar removal from the product gas.

Opis:
The qualitative analysis by synchronous luminescence technique was performed on aromatic fractions of primary tars obtained from humic and sapropelic coals (from Upper Silesia Basin). The synchronous luminescence technique, called also the technique of spectral fractionation, consists in the record of a spectrum at the constant difference between the positions of emission and excitation monochromators (Dl). This difference is calculated as a result of subtraction of effective emission and excitation wavelengths characterising compounds identified in investigated mixture. In relation with conventional luminescence technique, giving broad, low resolved bands in the conditions of ambient temperature, the synchronous luminescence technique enables to obtain well resolved and simplified spectra that facilitate the identification of individual components of the mixture. The application of this technique to analysis of aromatic fractions composition of primary tars from coals of various genesis and technological properties (sapropelic and humic coals) has shown a general similarity of composition with predomination of aromatic compounds containing 2-4 condensed rings. In the sample derived from sapropelic coal, a markedly higher intensity of bands is observed, attributed to aromatics of lower condensation degree (2-3 condensed rings), in relation with the bands of aromatics with higher intensity (3-4 condensed rings). The reverse relation is observed for sample from humic coal. In both analysed samples, a series of the following individual compounds has been identified from groups of aromatics: naphthalenes, acenaphthenes, benzofluorenes, anthracenes, pyrenes, and benz(a)anthracenes. Smaller amounts of benz(a)pyrenes, benz(ghi)perylene, and 3, 4-9, 10-dibenzopyrene were also encountered. The technique of synchronous luminescence made possible, therefore, the identification of individual components of complex mixture of aromatic compounds in coal derived products. This technique is thus of great value for the characteristics of aromatic compounds in thermolysis products of coal, in the cognitive aspect, as well as in monitoring of environment.

Opis:
Several pits, the remains of wood tar production using the so-called ‘vessel-less method’, were discovered in the Lublin region. They contained objects related to the early Middle Ages. These discoveries were used as the base for experiments run in 2013 in the experimental archaeology centre at Grodzisko Żmijowiska. The first experiment involved the acquisition of wood tar from birch bark, while the other attempts were aimed at extracting tar from pine stumpwood. The experiments were conducted in a shallow pit that was plastered with clay and had a small depression at its bottom used as a container for the tar, separated from the pit by a clay strainer. The raw material gathered in the pit was covered with a clay dome. When the dome was dry, it was slowly heated up with burning wood to the right temperature which was checked inside the dome with a thermocouple. Both processes were conducted successfully. The results were compared with experiments focused on the production of wood tar using the two-vessel method known in the early Middle Ages. The comparison showed that the vessel-less method is less economical due to the amount of fuel used and almost three times less efficient in terms of the raw material to final product ratio. However, it is very simple technically and allows the effective production of wood tar.

Opis:
The main problem with the biomass gasification is the presence of tar compounds in the process gas. Use of the produced gas in thermal machines such as internal combustion engines or turbines requires deep gas cleansing. For this purpose, several methods, characterized by varying degrees of effectiveness and complexity, are applied, namely: mechanical, thermal, plasma, catalytic, primary and mixed methods. The article presents the problems connected with the presence of tar and describes a wide range of methods used to remove it.
Podstawowym problemem związanym ze zgazowaniem biomasy jest obecność związków smół w gazach procesowych. Zastosowanie gazu generatorowego w maszynach cieplnych, takich jak silniki wewnętrznego spalania czy turbiny, wymaga głębokiego oczyszczenia gazu. W tym celu stosuje się wiele metod charakteryzujących się różną skutecznością i stopniem skomplikowania.Należą do nich metody: mechaniczne, termiczne, plazmowe, katalityczne, pierwotne oraz mieszane. W artykule przedstawiono problematykę związaną z występowaniem smół w gazie generatorowym oraz opisano szeroki zakres metod stosowanych w celu ich usunięcia.

Opis:
The paper presents an attempt to evaluate the impact of coal and coal mine methane cocombustion on the physics of the heat exchange in an 140 t/h pulverized-coal boiler through an analysis of 21 combinations of the boiler operating parameters – three different boiler loads (50, 75, and 100%) and seven values of the fired gas thermal contribution (0–60%). The obtained results are the temperature distribution of flue gas and steam in the boiler characteristic points, the heat transfer coefficient values for the boiler individual elements expressing the nature of changes in the heat transfer and the change in the boiler efficiency depending on how much gas is actually fired. An increase in the amount of co-fired gas involves a temperature increase along the flue gas path. This is the effect of the reduction in the amount of heat collected by the evaporator in the furnace. For these reason, the flue gas temperature at the furnace outlet rises by 9 K on average per a 0.1 increment in the fired gas thermal contribution. The temperature rise improves the heat transfer in the boiler heat exchangers – for the first- and the secondstage superheater the improvement totals 2.8% at a 10 pp. increase in the fired gas thermal contribution. However, the rise in the flue gas temperature at the boiler outlet involves a drop in the boiler efficiency (by 0.13 pp. for a rise in the fired gas thermal contribution by 0.1).

tar, cigarettes sold in Poland, time trends
Opis:
The content of tar in cigarettes sold in Poland in the years 1983–2000Cigarette smoke contains over forty carcinogenic compounds, including tar that is evaluated as carcinogen A for human beings. The World Health Organization recommends reduction of carcinogenic and toxic substances in cigarettes as one of the elements in cancer control programs and tobacco control policies. In the beginning of 1990s, the Polish norm for tar, nicotine and carbon monoxide was first time enforced in Poland. This paper makes an attempt to collect available data on the content of tar in cigarettes sold in Polish market between 1983 and 2000, analyze time trends for average tar content in these cigarettes, compare Polish data with study results from Unites States, Finland and other Central and Eastern European countries, and evaluate whether tobacco product control measures that have been enforced at that time contributed to reduction of tar in cigarettes sold in Poland and what was its potential impact on time trends in lung cancer mortality in the last decades.

Opis:
The catalytic conversion of a model tar compound, namely: naphthalene contained in a simulated producer gas from wood gasification process was investigated. The sol-gel approach was used to create a mesoporous Cepromoted Ni/alumina catalyst with high surface area. A surface area of 333 m2g was achieved by calcination of the mesoporous catalyst (17 wt% Ni and 2.8 wt% Ce) under air conditions at 1123 K. The catalysts were characterized using the N2 adsorption-desorption, XRD, and SEM techniques, and their promotion effect on producer gas reforming and tar removal was studied under dry, steam, and partial oxidation conditions. The Ni-based catalysts effectively converted naphthalene and increased the proportion of H2 and CO in the reformed gas. Incorporating Ce into the catalyst increased the proportion of H2 and CO in the reformed gas, while lowering the amount of CH4 and CO2. In the absence of oxygen, catalytic reforming of the producer gas resulted in 79.6% naphthalene conversion, whereas catalytic partial oxidation conditions resulted in 99.1% naphthalene conversion.

Opis:
This work aims at study the effect of the operating conditions like equivalence ration and temperature on the updraft gasification of beech wood. The main aspects was to analyze the influence of temperature distribution in the reactor and equivalence ratio on the fuel consumption, syngas composition as well as tar formation characteristics during the gasification process. The light tar content and composition were analysed using gas chromatography coupled with mass spectrometry (GC-MS). Experimental results have shown that the amount of air supplied does not affect the parameters of the gasification process linearly. For lower ER value there was high fuel consumption and high bed temperature in the gasifier, which results in high caloric value of syngas. The results showed that tar yield during updraft gasification depends on the temperature and equivalence ratio. With the increase value of ER and the decrease of temperature on the surface of the bed, the total amount of tar yield increased. The highest temperature on the surface of the bed leads to the smallest tar yield, which can be associated with thermal cracking. The results indicate that both light and heavy tar are changing nonlinearly with different operating conditions. In addition, with decreasing temperature and increasing ER values, the amount of phenol and oxidized aliphatic compounds in the tar samples increased while the BTEX amount decreased. The amount of PAHs, in relation to the temperature and ER, was kept low in all cases.

The use of electromagnetic conductivity and electrical resistivity geophysical techniques has been employed in this study to investigate the occurrence, thickness, and spatial distribution of bitumen deposit around Makun-Omi in the Ijebu Waterside area of southwestern Nigeria. Subsurface apparent conductivity distribution data obtained using Geonic 34-3 equipment along fifteen traverses which sounded from different depths of 7.5, 15, 30 and 60 m at inter-coil separation of 10, 20 and 40 m in vertical and horizontal coupling modes and ground resistivity distribution measurements, obtained using Geopulse Tiger Allied resistivity meter at fourteen Vertical Electrical Sounding (VES) stations, were processed and employed to characterize the subsurface in terms of tar sands distribution. The conductivity and resistivity distribution in the form of a 3D earth model, iso-depth maps, 2D sections generated from the processed conductivity and resistivity data indicate relatively low conductivity <20 mS/m and high resistivity >1300 Ωm values around tar/bitumen impregnated sands which mostly occurred in the southern part of the study area. Clearly defined conductivity and resistivity anomalies which delineate the lateral and vertical occurrence of tar impregnated sands underscore the efficacy of integrating electromagnetic and electrical resistivity geophysical techniques to identify occurrence of economic deposits of tar sands in parts of southwestern Nigeria.

Tar formation is a significant issue during biomass gasification. Catalytic removal of tars with the use of nickel cata-lyst allows to obtain high conversion rate but coke formation on catalysts surface lead to its deactivation. Toluene decomposition as a tar imitator was studied in gliding discharge plasma-catalytic system with the use of 5%, 10% and 15% by weight Ni and NiO catalyst on Al2O3 (α-Al2O3) and Peshiney (γ-Al2O3) carrier in gas composition similar to the gas after biomass pyrolysis. The optimal concentration of nickel was identified to be 10% by weight on Al2O3. It was stable in all studiedinitial toluene concentrations, discharge power while C7H8 conversion rate remained high – up to 82%. During the process, nickel catalysts were deactivated by sooth formation on the surface. On catalysts surface, toluene decomposition products were identified including benzyl alcohol and 3-hexen-2-one.

Opis:
Treatment of the soil by plants (phytoremediation), associated with the production of biomass for energy purposes, carries a number of significant problems with a practical and technical point of view. They concern mainly the way of the thermal conversion of biomass to energy production in an efficient and environmentally safe way. One way may be gasification. This process involves the conversion of organic matter into a combustible gas mixture by partial oxidation at high temperature under the influence of the gasifying agent (air, oxygen, steam, or mixtures of these components). Gasification aim is to obtain a combustible gas. Unfortunately, the formation of gas also accompanied by the formation of solid and liquid waste products. The paper presents the results of basic physico-chemical properties of solid (ash) and liquid (tar) waste products of the gasification process of the heavy metal contaminated energy crops. The gasification process has carried out in a laboratory fixed bed reactor. Two types of energy crops: Miscanthus x giganteus and Sida hermaphrodita were used. The experimental plots were established on postindustrial site - former sewage sludge dewatering area (Leipzig site, Germany). The results show that the gasification process, promotes the migration of harmful substances such as heavy metals from the fuel to the solid phase.
Oczyszczanie gleb za pomocą roślin (tzw. fitoremediacja), skojarzone z produkcją biomasy na cele energetyczne, niesie za sobą szereg problemów istotnych z praktycznego i technicznego punktu widzenia. Dotyczą one przede wszystkim sposobu konwersji termicznej wyprodukowanej biomasy na energię w sposób efektywny i bezpieczny dla środowiska. Jednym ze sposobów może być zgazowanie. Proces ten polega na przekształcaniu substancji organicznej w palną mieszaninę gazów przez częściowe utlenienie w wysokiej temperaturze pod wpływem czynnika zgazowującego (powietrza, tlenu, pary wodnej lub mieszanin tych składników). Zgazowanie ma na celu uzyskanie palnego gazu. Niestety powstawaniu gazu towarzyszy również powstawanie stałych i ciekłych produktów odpadowych. W pracy przedstawiono rezultaty badań podstawowych właściwości fizyczno-chemicznych stałych (popiół) i ciekłych (smoły) produktów odpadowych pochodzących z procesu zgazowania roślin energetycznych uprawianych na terenie zdegradowanym ekologicznie. Proces zgazowania prowadzono w laboratoryjnym reaktorze ze złożem stałym. Wykorzystano dwa rodzaje roślin energetycznych: miskanta olbrzymiego oraz ślazowca pensylwańskiego. Rośliny pozyskano z nieużytku poprzemysłowego z okolic Lipska (Niemcy), na którym składowano komunalne osady ściekowe. Wyniki pokazują, że zgazowanie jako proces przekształcania substancji organicznej w gaz przy jednoczesnej produkcji stałych i ciekłych produktów odpadowych promuje migrację szkodliwych związków, takich jak metale ciężkie, występujących w paliwie, do fazy stałej i ciekłej.

Opis:
Gliding discharge and coupled plasma-catalytic system were used for toluene conversion in a gas composition such as the one obtained during pyrolysis of biomass. The chosen catalyst was G-0117, which is an industrial catalyst for methane conversion manufactured by INS Pulawy (Poland). The effects of discharge power, initial concentration of toluene, gas flow rate and the presence of the bed of the G-0117 catalyst on the conversion of C7 H8 , a model tars compounds were investigated. Conversion of coluene increases with discharge power and the highest one was noted in the coupled plasma-catalytic system. It was higher than that in the homogeneous system of gliding discharge. When applying a reactor with reduced G-0117 and CO (0.15 mol%), CO2  (0.15 mol%), H2  (0.30 mol%), N2  (0.40 mol%), 4000 ppm of toluene and gas flow rate of 1.5 Nm3 /h, the conversion of toluene was higher than 99%. In the coupled plasma-catalytic system with G-0117 methanation of carbon oxides was observed.
