In general this small alcohol molecule is methyl and the product is named Fatty Acid Methyl Ester (FAME). In this study; A new biodiesel production method was investigated. This new method is depend on the catalysis effect of chitosan biopolymer. The trans esterification reaction was carried in the presence of different amounts of chitosan biopolymer. The biodiesel product was analyzed with (UV-visible, flash test). The collected data will be used for the planning of future studies. © 2016 IEESE. All rights reserved. 1. Introduction In recent years, decreasing supply of oil, steadily rising oil prices and the adverse environmental effects of fossil fuels; has led to the importance of alternative energy sources [1]–[3]. The raw materials used in the alternative diesel fuel, oils of vegetable or animal origin. Biodiesel, is defined as mono alkyl esters of long chain fatty acid derived from fat of animal or vegetable [4]. Biodiesel is produced by transesterification reaction. The transesterification reaction is defined as the process of the triglyceride molecules react in the presence of alcohol, to produce fatty esters, and glycerol [5]. In the production of Fatty Acid Methyl Ester (FAME) the most commonly used alcohol is methyl alcohol. It is more productive than the other alcohols and obtained at low cost [6]. Fig. 1.
