Opis:
Sustainable economic and industrial growth requires safe, sustainable resources of energy. For the future rearrangement of a sustainable economy to biological raw materials, completely new approaches in research and development, production, and economy are necessary. The biofuels produced from the renewable resources could help to minimize the fossil fuel burning and CO2 production. Biofuels produced from biomass such as plants or organic waste could help to reduce both the world’s dependence on oil and CO2 production. These biofuels have the potential to cut CO2 emission because the plants they are made from use CO2 as they grow. Biofuels and bio products produced from plant biomass would mitigate global warming. The ‘first-generation’ biofuels appear unsustainable because of the potential stress that their production places on food commodities. For organic chemicals and materials these needs to follow a biorefinery model under environmentally sustainable conditions. Where these operate at present, their product range is largely limited to simple materials (i.e. cellulose, ethanol, and biofuels). Second generation biorefineries need to build on the need for sustainable chemical products through modern and proven green chemical technologies such as bioprocessing including pyrolysis, Fisher Tropsch, and other catalytic processes in order to make more complex molecules and materials on which a future sustainable society will be based. The article presents the basic processes of converting liquid and gaseous biofuels and second-generation.

Opis:
The production of biofuels using wastewater as a microalgae culture medium is a little explored technology, but with potential for success. In order to contribute to the knowledge of these technologies and their technical feasibility for microalgae growth, in this work the Chlorella sp. strain was cultivated in two types of effluents generated in an experimental farm located in eastern Colombia, before and after a biological treatment process. The consumption of the main nutrients that regulate growth and lipid production was evaluated, in order to extract, quantify, characterize and convert them into biodiesel. The results showed that Chlorella sp. growth and lipid production is more favourable in R2 medium of treated water than in R1 medium of raw water, mainly due to phosphorus limitation and higher N-NO3 concentration in R2 compared to R1. In the R2 medium culture, a percentage of 42.54% of long-chain fatty acids was found, which is necessary to obtain a high quality biodiesel. Finally, the best transesterification experiment allowed reaching a fatty acid methyl esters (FAME) percentage of 90.1 ± 2.7%. In general, the results demonstrated the potential viability of using the wastewater generated in the San Pablo farm to produce biomass with lipid content to obtain biodiesel, finding that where the concentration of nutrients, mainly nitrogen, has a great influence on the microalgal metabolism for lipid accumulation.

Opis:
The aim of the study was to determine the environmental potential impact of the palm shell biofuel production process using life cycle assessment (LCA) through gate to gate approach. The environmental impact of each scenario was assessed using ISO 14040 (2006), which includes goal and scope definition, life cycle inventory (LCI), life cycle impact assessment (LCIA) and interpretation. The simapro v.9 software with ecoinvent 3.5 database was utilized to assess the environmental effect. The impact analysis method used is Impact 2002+. Functional units were used to show environmental references in damage assessment and characterization, such as energy use and global warming potential. The results show that the environmental impact evaluation obtained through LCA for the entire biofuel production process stated that the thermal cracking stage resulted in the highest global warming impact, compared to other processes, which was 118.374 kg CO2 eq. For the categories of human health, ecosystem quality, and climate change, each has a value of 0.0001 DALY; 15.708 PDF•m2•yr; and 335.233 kg CO2 eq where this value is the total damage assessment of the entire biofuel production process. From the results of the analysis by utilizing the networking graph on the simapro application, it can be seen that the environmental hotspot of the thermal cracking process of biofuel production is due to the use of electricity from the State Electricity Company (PLN) and the release of chemical substances from the process. To improve the environmental performance of biofuel production process, additional development steps are required to increase biofuel yield, purification efficiency of biofuel to obtain pure liquid fuel, and the use of renewable energy sources to generate electricity. Additionally, more particular data would be required for a more precise LCA study result.

Opis:
In several our publications energetic efficiency of biofuel production was defined as a ratio of the amount of energy obtained in a form of biofuel to the sum of energy contributions necessary to conduct production processes on all the production stages. It was also shown that such a definition enables subsequent inclusion of production steps due to additivity of reciprocals of energetic efficiency determined separately for each step. In the present work, several scenarios of the transport of biomass between plantation and industrial facility converting biomass into biofuel are considered, appropriate values of energetic efficiency are computed and compared. The analysis is confined to biodiesel production based on rapeseed. The results show substantial differences caused by various approaches to that stage of transport.

Opis:
Mając na względzie globalny trend poszukiwania paliw przyjaznych dla środowiska, w szczególności paliw niskoemisyjnych, zwrócono uwagę na technologię konwersji metanu do wodoru. W artykule przedstawiono sposób obliczania emisji GHG w cyklu życia biowodoru produkowanego poprzez pirolizę (bio)metanu. Technologia ta wydaje się przyszłościowa ze względu na fakt, że pozwala uzyskać zeroemisyjne paliwo. Podczas tego procesu otrzymuje się czysty wodór i stały węgiel. Węgiel może być wykorzystany przez wiele różnych gałęzi przemysłu, niekoniecznie jako paliwo. Zgodnie z dyrektywą 2018/2001 biopaliwo musi wykazać spełnienie założonego progu redukcji emisji GHG. Dlatego jest niezmiernie ważne, aby oceniać każdą nową technologię pod kątem emisyjności produktu. Obliczenia zostały przeprowadzone zgodnie z metodyką ustanowioną w dyrektywie 2018/2001, a w szczególności zgodnie z dokumentacją systemu KZR INiG. Do przeprowadzenia oceny przyjęto następujące założenia: model jednostki przetwórczej oraz dane wejściowe do tego etapu zaczerpnięto z danych literaturowych; przyjęto, że surowiec stanowi biometan produkowany z bioodpadów; obliczenia dla etapu pirolizy przeprowadzono jako obliczenia wartości rzeczywistych, natomiast dla pozostałych etapów cyklu życia biowodoru przyjęto wartości standardowe z dyrektywy 2018/2001. Badania wykazały, że wodór może osiągnąć poziom 69% redukcji emisji GHG w porównaniu z paliwem kopalnym (jako odpowiednik paliwa kopalnego wykorzystano wartość 94 gCO2eq/MJ). Jest to niewiele więcej niż wymagany próg 65%. Oznacza to, że podczas prac nad rozwojem tej technologii aspekty emisji GHG muszą być mocno brane pod uwagę.
Bearing in mind the global trend of looking for environmental friendly fuels, in particular low carbon fuels, methaneto-hydrogen conversion technology was noticed. The process of calculation of life cycle GHG emissions from biohydrogen produced via (bio)methane pyrolysis was presented in the article. This technology seems to be future-proof in that it produces zero-carbon fuel. During this process, pure hydrogen and solid carbon are received. Carbon can be used in various branches of industry, not necessarily as fuel. According to the 2018/2001 Directive, biofuel has to achieve set GHG emission threshold. Thus it is extremely important to assess each new technology in terms of the emissivity of the product. The calculations were performed according to the methodology set out in the 2018/2001 Directive in particular according to the KZR INiG System documents. In order to carry out the assessment, the following assumptions were made: the model of the conversion unit and input data for this stage were obtained from literature data; the raw material was biomethane obtained from bio-waste; calculations for the pyrolysis stage were performed as actual values for the remaining stages of the life cycle of biohydrogen, the standard values from the 2018/2001 Directive were adopted. The research showed that hydrogen can reach 69% GHG emission saving in comparison to the fossil fuel (for the fossil fuel comparator the 94 gCO2eq/MJ values was used). This value is slightly higher the required threshold of 65%. It means that GHG emission aspects need to be carefully taken into account when developing this technology.

Opis:
The article presents the laboratory tests results of the influence of the diesel oil content in a mixture with rapeseed oil on the operating parameters of a diesel engine with the CommonRail fuel supply system. Fuel mixtures with a rapeseed content of 0%, 50%, 70%, 100% were used. The article presents the results of tests carried out for various configurations of the object. The measurements included tests of exhaust gases: the content of carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides as well as specific fuel consumption and exhaust gas temperature. As a result of the research, it was noticed that the use of rapeseed oil causes a significant increase in fuel consumption and an increase in emissions. At a crankshaft speed of 2500 rpm and a torque generated by the engine crankshaft of 12 Nm, the specific fuel consumption for a 0% rapeseed content is 310 g/kWh. For the same engine operating conditions and the same rapeseed content of the fuel, the fuel consumption for 100% rapeseed content is 330 g/kWh. For the same engine operating parameters, analysis of the carbon dioxide content in the exhaust gas yields a value of 7.8x104 ppm for a rapeseed content of 0%. For the same engine operating conditions and for the oilseed rape content in the fuel is 100% 8.4x104 ppm. The mathematical models describing the effects of engine operating parameters and rapeseed oil content in the mixture on the observed values were created with the Scilab program. The degree of agreement of the determined mathematical models was checked by calculating the coefficient of determination (R2). The results are shown in 3D figures.

Opis:
The manufacturing of Catfish products has been developed rapidly in the Mekong delta. Every year, about 1.2 million tons of Catfish and 150,000 tons of biofuel are produced. The biofuel B100 manufactures in Mekong delta satisfies the America standard ASTM D6751; EURO EN 14214 or Vietnamese standard TCVN 7717. Mekong delta, a lower land area, has a large inland water way system with around 100.000 river boats that operate with marine diesel engine. Using the biofuel for the marine diesel engine in area will reduce the HC, CO, SOx and NOx emission to the environment. Therefore, with a study on applying the catfish biofuel, it will reduce the climate change by the increasing of sea water level and save energy by using green energy to replace petrol oil.

Biofuel production, as well as any other production processes, involves a number of conversion steps each of those is connected with unavoidable consumption of energy. Since biofuels are intended to replace fossil fuels it is important that the sum of energy inputs into subsequent technological steps does not exceed the energy output from the system. Basing on theoretical model derived recently by present authors, energy require-ments for several agricultural technologies are computed, and used for estimation of energetic efficiency of rapeseed plantations dedicated for biodiesel fuel production. The effects of technological choices on energetic efficiency of plantations are demonstrated basing on numerical compu-tations performed using realistic data.

Opis:
Future options for addressing the depletion of fossil fuels and reducing pollution from internal combustion engines may include biofuel as an alternative fuel. This study aims to experimentally and statistically assess the effect of using diesel-biofuel blends on the emissions of a single-cylinder direct-injection engine. Using recycled olive oil, a chemical Tran’s esterification process was used to create biofuel. The experimental results were contrasted with those of a one-dimensional engine model for exhaust emissions and torque, which showed high agreement between test and numerical data. In order to comprehend the factors that affect the engine’s reaction to variations in fuel composition, the thermodynamic characteristics of the engine for various blends were also supplied. According to the investigation, a mixture with 20% of the volume fraction of oleic acid methyl ester olive-based biofuel and 80% of the volume fraction of pure diesel can be an effective fuel alternative for cleaner exhaust emissions while offering almost the same performance.

Celem badań była ocena doraźnego wpływu surowej, nieoczyszczonej fazy glicerynowej, powstałej w wyniku transestryfikacji oleju posmażalniczego, na wegetację roślin. Badania podstawowe wykonano na poletkach doświadczalnych, założonych na trwałych użytkach zielonych oraz w donicach z kukurydzą. Na sześciu poletkach o powierzchni 1,5 m2 każde rozprowadzono równomiernie wodny roztwór fazy glicerynowej, dwukrotnie w ilości: 3, 33, 66, 100 kg fazy glicerynowej przeliczonej na ha oraz trzeci raz w ilości: 200, 500, 750, 1000 kg*ha-1. Do donic, wypełnionych 16 kg ziemi, wprowadzono jednorazowo fazę glicerynową w ilości: 0,5, 2,5, 5,0 g, również w postaci wodnego roztworu. Określano przyrost względny masy zielonej w stosunku do masy zebranej na poletkach kontrolnych. Nie zaobserwowano istotnego wpływu fazy glicerynowej na zmianę masy zielonej, zbieranej na terenie trwałych użytków zielonych, natomiast zaobserwowano hamujące oddziaływanie na przyrost kukurydzy uprawianej w donicach. W wyniku analizy chemicznej fazy glicerynowej wykazano 17-procentowy udział metanolu. Ze względu na ryzyko skażenia środowiska stwierdzono, że konieczne jest usuniecie tego związku przed wprowadzeniem większej ilości fazy glicerynowej do gleby.
The study aimed at evaluating the influence of raw, unrefined glycerol phase, resulted from transesterification process of waste cooking oil, on plant vegetation. Basic investigations were conducted on experimental plots, established on the permanent grassland and in the pots with maize plants. On six plots of 1.5 m2 area each, the aquaeous solution of glycerol phase was uniformly distributed three times: twice at the rates of 3, 33, 66, 100 kg glycerol phase per 1 ha, and the third time - at the rates of 200, 500, 750, 1000 kg*ha-1. To the pots, filled up with 16 kg soil, the glycerin phase was added once in doses 0.5 g, 2.5 g and 5.0 g, also in aqueous solution. The gain of green matter was determined in relation to green matter of crop harvested from the control plots. No significant effects of the glycerin phase on relative changes in green matter yield harvested from the terrain of permanent grassland, were found. However, an inhibitory impact on the growth of maize plants in pots was observed. The chemical analysis of glycerin phase showed 17% methanol content in it. Due to the risk of environment contamination it is necessary to remove methanol before introducing more glycerol phase into soil.
