In the present study, the high viscosity of the jatropha curcas oil was decreased by preheating. The effect of fuel inlet temperature on performance of diesel engine is evaluated. A single cylinder, four stroke, constant speed, air cooled, direct injection diesel engine developing a power output of 3.7 kW at 1500 rev/min typically used in agricultural sector was tested using neat jatropha oil a...

Abstract According to this study, the combined NOx and Smoke Opacity of waste plastic oil N-Octanol are higher than diesel fuel. To find optimal combination, was blended with diesel. The best blend (10%, 20%, 30%) contrasted a N-Octanol. Five load variations have been tested using stationary, single-cylinder Kirloskar engine bore stroke 85 110 mm. G-power estimated G-Power tool v-3.1.9.7, sampl...

Algae are widely used as biosorbent for the sorption of heavy metals, however sorption of oil on algae has not been explored. Algae in marine and fresh water environment may affect the fate and transport of spilled oil. Sorption of diesel and lubricating oil was studied using dead biomass of Spirulina sp. and Scenedesmus abundans. The rate and extent of sorption was studied in well mixed batch ...

The amount of used restaurant oils diverted to biodiesel production in the United States is increasing due to growing consumer interest, the emergence of biodiesel cooperatives, and increased commercial capacity (NBB 2006). Biodiesel, a renewable fuel used as an alternative or additive to conventional diesel, offers several benefits: biodiesel burns cleaner than conventional diesel, it can be p...

background diesel oil hydrocarbons are the most common contaminants of our biological environment. considering the fact that iran is one of the major producers of diesel oil products, it greatly contributes to soil and water pollution. currently, soil and water pollutions caused by diesel oil products leakage, from distribution stations, is one of the major concerns in iran. based on the studie...

As crude oil price reach a new high, the need for developing alternate fuels has become acute. Alternate fuels should be economically attractive in order to compete with currently used fossil fuels. In this work, biodiesel (ethyl ester) was prepared from waste cooking oil collected from a local restaurant in Halifax, Nova Scotia, Canada. Ethyl alcohol with sodium hydroxide as a catalyst was use...

biofuels are the main substitute to fossil fuels. these fuels are less polluting in compari-son to fossil fuels and can be produced from agricultural material residues for use in die-sel engines. in this research work bioethanol was produced from potato waste. it was de-hydrated in a vapor phase using 3a zeolite and was used in combination with sunflower methyl ester oil and diesel fuel blendin...

In this study, among the 21 diesel-degrading bacteria that were isolated from an oil-polluted area in Fars (Iran), 6 bacterial strains were tested for their capability to metabolize and grow on diesel oil by degrading its hydrocarbons content. The biochemical characteristics and 16S rRNA sequence analysis of diesel-degrading bacteria showed that these strains were related to the genus Pseudomon...

The present work is focused on determining the performance and emission characteristics biodiesel in DI diesel engine. Experimental investigation of diesel engine was made with 25% (B25), 50% (B50) and 75% (B75) and 100%(B100) blending of Ziziphus jujuba oil with diesel and the results were compared with diesel. Keywords— Ziziphus jujuba, Indian jujube, Edible, Blending, direct injection (DI) d...
