Biodiesel production is the act of producing the biofuel, biodiesel, through either transesterification or alcoholysis. The process involves reacting vegetable oils or animal fats catalytically with a short-chain aliphatic alcohols (typically methanol or ethanol). Steps in the processThe major steps required to synthesize biodiesel are as follows: Feedstock pretreatmentIf waste vegetable oil (WVO) is used, it is filtered to remove dirt, charred food, and other non-oil material often found. Water is removed because its presence causes the triglycerides to hydrolyze, giving salts of the fatty acids (soaps) instead of undergoing transesterification to give biodiesel. Determination and treatment of free fatty acidsA sample of the cleaned feedstock oil is titrated with a standardized base solution in order to determine the concentration of free fatty acids (carboxylic acids) present in the waste vegetable oil sample. These acids are then either esterified into biodiesel, esterified into bound glycerides, or removed, typically through neutralization. From Wikipedia under the

Asked by sagar - Wed Dec 19 06:35:31 2007 - - 2 Answers - 0 Comments A. PUFAs are long-chain fatty acids containing two or more double bonds. They provide structural & functional characteristics, and are involved in a wide range of biological components including membranes (in phospholipids). Equally important PUFAs serve as precursors for conversion into metabolites that regulate critical biological functions. Biodiesel is a non-petroleum and environmentally-friendly alternative to petroleum-based diesel fuel and not fatty acid. PUFA is fatty acid it is not used!
