TL;DR: In this paper, the biodegradability of various biodiesel fuels was examined by the CO2 evolution method (EPA 560/6-82-003), BOD5 (EPA 405.1), COD (EPA 410), and gas chromatography (GC) analyses in an aquatic system.
Abstract: The biodegradability of various biodiesel fuels was examined by the CO2 evolution method (EPA 560/6-82-003), BOD5 (EPA 405.1), COD (EPA 410), and gas chromatography (GC) analyses in an aquatic system. The fuels examined included the methyl- and ethyl-esters of rapeseed oil and soybean oil, neat rapeseed oil, neat soybean oil and Phillips 2-D low sulfur, reference petroleum diesel. Blends of biodiesel/petroleum diesel at different volumetric ratios, including 80/20, 50/50, and 20/80, were also examined. The results demonstrate that all the biodiesel fuels are “readily biodegradable”. Moreover, in the presence of REE, the degradation rate of petroleum diesel increased to twice that of petroleum diesel alone. The pattern of biodegradation in the blends and reasons why biodiesel is more readily degradable than petroleum diesel are discussed. The biodegradation monitoring results from both CO2 evolution and GC methods are compared.

Journal ArticleDOI
TL;DR: The most important variables affecting methyl ester yield during the transesterification reaction are the molar ratio of alcohol to vegetable oil and the reaction temperature as discussed by the authors, which is the commonly used alcohol in this process, due to its low cost.

TL;DR: Biodiesel is defined as the monoalkyl esters of vegetable oils or animal fats as mentioned in this paper and is the best candidate for diesel fuels in diesel engines, which is the main advantage that biodiesel has over gasoline and petroleum diesel.

TL;DR: In this paper, the authors have discussed the development of biodiesel and its latest aspects of development, including biodegradability, kinetics involved in the process of the biodiesel production, and its stability.
Abstract: An ever increasing demand of fuels has been a challenge for today’s scientific workers. The fossil fuel resources are dwindling day by day. Biodiesel seems to be a solution for future. Biodiesel is an environmentally viable fuel. Out of the four ways viz. direct use and blending, micro-emulsions, thermal cracking and transesterification, most commonly used method is transesterification of vegetable oils, fats, waste oils, etc. Latest aspects of development of biodiesel have been discussed in this work. Yield of biodiesel is affected by molar ratio, moisture and water content, reaction temperature, stirring, specific gravity, etc. Biodegradability, kinetics involved in the process of biodiesel production, and its stability have been critically reviewed. Emissions and performance of biodiesel has also been reported. 2008 Elsevier Ltd. All rights reserved.
