Preparation of Methyl Esters of Solid Acids from Litsea Consimilis
Abstract: This study focuses on the extraction and characterization of fatty acids from the seed oil of Litsea consimilis and their subsequent conversion into methyl esters. The oil demonstrated high iodine and Reichert-Meissl values, indicating a significant content of unsaturated and short-chain fatty acids. Glyceride analysis revealed that trilaurin constitutes over 90% of the triglycerides, confirmed through melting point analysis and hydrolysis yielding lauric acid as the sole component. The oil …

Performance, Emission, and Combustion Evaluation of Chlorella Vulgaris Biodiesel-Diesel Blends in a Compression Ignition Engine
Abstract: This study examines, without modifying the engine, the performance, emissions, and combustion properties of biodiesel blends made from Chlorella vulgaris microalgae in a four-stroke, single-cylinder, water-cooled CI engine. The blends of biodiesel and diesel, designated B10, B20, B30, and B40, were 10%, 20%, 30%, and 40%, respectively. Of these, B20 showed the best efficiency-to-emissions ratio. Although it recorded the lowest brake specific fuel consumption of 0.232 kg/kWh, indicating superior fuel …

Evaluation of the Emission and Engine Operability of Biodiesel and Biodiesel Blends Produced from Alkali-Catalyzed Esterification and Transesterification of Jatropha Oil Feedstock
Abstract: This study reports on the engine performance analysis of biodiesel and blends produced from jatropha-based bio-oil feedstock via combined esterification and transesterification process, the physiochemical of the bio-oil, and subsequent biodiesel produced. Jatropha bio-oil was characterized to determine its fuel properties. A liquid phase transesterification reaction at 60 min reaction time, 50°C temperature, using a methanol-oil molar ratio of 40:1 and 0.35 g of sodium hydroxide (NaOH) catalyst was carried …

Optimization of Reaction Parameters for Biodiesel (Methyl Ester) Synthesis Using Surface Response Methodology
Abstract: The Polyoxo vanadate catalytic trans-esterification of waste cooking oil (WCO) was carried out by optimizing four reaction parameters which include: catalyst loading, methanol/oil ratio, temperature, and reaction time. These optimized parameters are 0.5 g, 0.8 g, and 1.2 g catalyst loading, 3:1, 6:1 and 9:1 methanol/oil ratio, 45°C, 60°C and 65°C reaction temperature, 45 min, 60 min and 90 min reaction time. The regression equation in the uncoded units of …

Performance Analysis of Diesel Engine Using Hemp Biodiesel, Butanol and Diesel Fuel Blend
Abstract: The present study evaluates the possibility of using Hemp oil blended with Butanol (C4H9OH) & conventional diesel as an alternative fuel. Biodiesel is generated from hemp oil by transesterification. Hemp biodiesel is blended with conventional diesel & Butanol in distinct proportions such as B10 (10% hemp biodiesel+ 90% conventional diesel), B10Bu10 (10% hemp biodiesel+ 10% butanol+ 80% conventional diesel), B10Bu20 (10% hemp biodiesel+ 20% butanol+ 70% conventional diesel), B20 (20% …

Productions and Characterization of Biodiesel by Base Catalyzed Transesterification Reaction from Dairy Waste Scum of DEI Dairy, Agra
Abstract: With the increase in prices and rapid depletion of petroleum-based fuels, the investigation is being done to look over an alternative fuel source. Presently, the biodiesel is mainly produced from vegetable sources such as jatropa oil, karanja oil, rapeseed, soybean, and others that could overlap with nutritional requirement of the society if produced at large scale. Also, the production cost of biodiesel from vegetable and animal sources is very high …
