Biodiesel production through the use of different sources and characterization of oils and their esters as the substitute of diesel: A review

摘要: The world is confronted with the twin crises of fossil fuel depletion and environmental degradation. indiscriminate extraction consumption fuels have led to a reduction in petroleum reserves. Petroleum based are obtained from limited These finite reserves highly concentrated certain region world. Therefore, those countries not having these resources facing foreign exchange crisis, mainly due import crude oil. Hence it necessary look for alternative fuels, which can be produced materials available within country. Although vegetative oils diesel engines, but their high viscosities, low volatilities poor cold flow properties investigation its various derivatives. Among different possible sources, fatty acid methyl esters, known as Biodiesel derived triglycerides (vegetable oil animal fates) by transesterification methanol, present promising substitute received most attention now day. main advantages using renewability, better quality exhaust gas emission, biodegradability organic carbon photosynthetic origin. It does contribute rise level dioxide atmosphere consequently green house effect. This paper reviews source production characterization vegetable ester future possibilities production.
