Solid coconut waste was produced after coconut milk extraction process and may still contain up to 24 wt.% oil content. In this work, extraction of oil from coconut waste using batch and soxhlet extractor was studied. Effect of particle size diameter, type of solvent and solvent to solid ratio on the kinetic and thermodynamic parameters; entropy, enthalpy and free energy of extraction were inve...

The use of biodiesel, the methyl esters of vegetable oils are becoming popular due to their low environmental impact and potential as a green alternative fuel for diesel engine. The aim of this study is to potential use of Pongamia oil methyl ester as a substitute for diesel fuel in diesel engine. Various proportions of Pongamia and Diesel (B25, B50, B75, and B100) are prepared by transesterifi...

In this study, Biodiesel -Dimethyl Ether (BDE ) was tested in a 4-cylinder direct-injection diesel engine to investigate the performance and emission characteristics of the engine under five engine loads at the maximum torque .The engine speed was maintained at 1500 rpm. Here the jatropha oil is used as a non edible oil to produce the biodiesel. The dimethyl ether is used as an additive to enha...

Cedar wood oil is ranked the tenth essential oil in the world, it can be obtained from fir wood waste, and high added value Cedar series perfumes are obtained from Cedar wood oil by chemical processing. Their aroma is very unique and cannot be replaced. At present, the cedar wood resources are dwindling; a serious influence had taken place in the flavor and fragrance industry. Study found that ...

The characterization of pyrolysis oil obtained from mixed waste plastics and its utilization in a compression ignition engine were investigated. chemical compositions physicochemical properties distilled plastic (WPO) crude (CWPO) analyzed. experiment was conducted with variable ratio diesel at various loads ratios to evaluate combustion characteristics, exhaust emissions, performance. experime...
