Opis:: The possibility of obtaining sorbents with a good sorption capacity from miscanthus has been investigated. The chars and the activation products were obtained from the miscanthus in a rotary furnace. The activation process of miscanthus was carried out by water vapour at 700 - 800°C and at the activation time of 30 - 90 min. We found that the optimum conditions for the activation process were: the activation temperature of 750°C (activation time of 60 and 90 min) and 800°C (activation time of 45 or 60 min). For these conditions the sorbents with the best sorption capacity for p-chlorophenol, toluene, methylene blue and Congo red were obtained.

Opis:: For many years research has been conducted on using water added to the process of combustion in a compression-ignition engine (by injection to the suction manifold, disintegrated in the manifold by ultrasounds, injection to the cylinder or in the form of emulsion) in order to improve the engine's operating indices and reduce its smoking and toxicity. The study presents the effects of adding water to fuel on selected toxicity indices of exhaust gases, and puts forward the problem of technical usability of a water solution of hydrogen peroxide for the discussed purposes. The effect of water proportion in fuel on the change of the engine smoking, concentration of NOx in exhaust gases in the function of water proportion of water injected, concentration of NOx in the function of rotational speed for standard fuel and emulsion fuel, the effect of water proportion in the emulsion fuel on the relative value of the engine torque, concentration of CO in exhaust gases in the function of the engine load for different water proportions concentration of NOx in exhaust gases in the function of the engine load for different water proportions, specific fuel consumption in the function of the engine load for different water proportions are illustrated in the paper.

Opis:: In the first research studies series a selection of the quantitative composition of catalyst active phase composition (iron, copper and manganese) deposited on mineral-carbon support was carried out. It was found on the basis of the selection studies series that the best results were attained when copper and manganese were used as catalyst components. The quantitative composition of the denitrogention catalyst was estimated using a statistical method of experiment planning and metals content changed in the range 0.5 - 1.5wt % for both metals. Catalyst activity in nitric oxide reduction by ammonia was determined in the dependence on an active phase composition in the temperature range 100 - 200° C, at GHSV (Gas Hour Space Velocity) 6 000 and 10 000 Nm3/m3h, NO concentration 400 ppm, NH3/NO ratio 1:1. A graphic presentation of the obtained results was made using the UNIPLOT program. The highest activity in nitric oxide reduction by ammonia presented copper - manganese catalysts prepared by the impregnation of mineral-carbon support with active metals salts solutions and calcination after each metal impregnation with copper (up to 1.5 wt %) and manganese (up to 1.5 wt %).

Opis:: The information on the quantity of various types of combustible wastes registered in the Lower Silesia Marshal Office over the 2003 - 2005 years (waste codes - 02, 03, 04, 07, 12, 15, 16, 17, 19 and 20) was collected and then the quantities of individual wastes from different sources were summarized depending on the waste sort i.e. waste paper (cellulose), plastics, timber, textiles and rubber. The physiochemical properties and the chemical composition of the impurities in the selected waste sorts were determined and discussed while taking into account their usefulness and the necessary treatment operations for the alternative fuels production.

Opis:: This paper is focused on problem of quality of diesel commercial fuels in Polish market and an effect of their properties as well on engine parameters as environment The academic staff from Wrocław University of Technology put the own experience to the huge discussion by making research in the Wroclaw-city, where some probes of fuels were taken from six different commercial fuel stations. Chemical and physical properties of fuels were checked. A real diesel engine VW 1,9 TDI was investigated in university lab of Division of Motor Vehicles and Internal Combustion Engines. Typical engine performances were built including power, torque, fuel consumption, toxicity levels due to different fuels. The IC engine on the test bench, oxygen content in fuels, example of full load performance of VW1,9 TDI for fuel Bio D20-type, differences of mean effective pressure for different fuels, differences of carbon monoxide in exhaust for different fuels, differences of nitric oxides in exhaust for different fuels, differences of smog level in exhaust for different fuels, differences of heat release for different fuels, relation between engine torque and oxygen content in fuels vs. engine rotation are presented in the paper.

Opis:: Nitric oxides (NO) concentration in exhaust gases of self-ignition engine is a result of air usage for hydrocarbon fuel compounds oxidation in combustion process. The methods of limitation of NOx concentration based on adjusting optimization of injection advance angle and they are responsible for aim conflict in exhaust smokiness sphere. The progressive expectation of European Union, defined by Euro V and still discussable Euro VI implementation, caused a necessary of reaching for solutions apart from an engine like exhaust gas recirculation (EGR), selective catalytic reduction (SCR) and diesel particle filters - DPF. The method of water addition (especially the most effective - in water-fuel emulsion form) to combustion process has been known since years. This paper presents the results of the researches which aim was to investigate nitric oxides concentration in exhausts of one-cylinder self-ignition engine (typeS301D)fueled l0%, 20%, 30% water-emulsion fuel. Using of emulsion cut down emission nitric oxides (NOx), carbon monoxide and smoking of an engine with relation to fuelled with diesel oil. Using of the fuel containing 20% H2O cut down emission NO approx. 61%, emission NOx approx.67%, carbon monoxide approx. 20% with relation to fuelled with diesel oil.
W pracy przedstawiono wyniki badań wpływu zasilania silnika o zapłonie samoczynnym (typu S301D) paliwem emulsyjnym, zawierającym 10, 20 i 30% wody. Obserwowano stężenia tlenku azotu i tlenków azotu, tlenku węgla oraz dymienie silnika. W celu porównania efektów wyznaczono emisje jednostkowe poszczególnych wielkości i odniesiono je do takich wielkości wyznaczonych dla handlowego oleju napędowego. W przypadku NOx i CO zaobserwowano ekstremum efektu dla zawartości 20% wody; w przypadku dymienia silnika maksymalny efekt odpowiada maksymalnemu udziałowi wody w paliwie. Użycie paliwa emulsyjnego obniża emisję tlenków azotu (NO), tlenku węgla (CO) i dymienie silnika (S) w stosunku do zasilania olejem napędowym. W obszarze tlenku azotu (NO) użycie paliwa zawierającego 20% H2O spowodowało obniżenie emisji NO do poziomu 61% w stosunku do zasilania olejem napędowym. W obszarze tlenku węgla (CO) użycie paliwa zawierającego 20% H2O obniża emisję do poziomu 20% w stosunku do zasilania silnika olejem napędowym W obszarze tlenków azotu (NO) użycie paliwa zawierającego 20% H2O obniżyło emisję NOx do poziomu 67% w stosunku do zasilania olejem napędowym.
