Abstract :
A series of heterogeneous catalysts was synthesized and tested in transesterification reaction in order to produce methyl esters called biodiesel. The sunflower oil and methanol were used for this research and calcinated fish bone is used as a heterogeneous catalyst. The novelty of our research is type of support because fish bone is waste material in Iran. Also Iran has a many waste fish bones that are unusable. Fish bones are calcinated at 700,800,900 and 1000 C for 3 hours and then characterized by the XRD, BET. The best temperature was 1000 C. also Li as active sites was impregnated on support. The best synthesized catalyst was 5% Li on calcinated fish bone at 1000C. Under optimum reaction conditions of methanol/oil molar ration of 20:1, 10 wt% catalyst at 65 C , 91% conversion was obtained in 2.5 h of reaction duration with rpm 250.
Keywords : fish bone transesterification biodiesel heterogeneous.
