摘要
Biodiesel production from non-edible rubber seed oil with high free fatty acid (FFA 26%) content was investigated. Rhizopus Oryzae Lipase in the form of free powder was used as catalyst. The effect of reaction parameters such as catalyst concentration, reaction duration, pH of the reaction mixture, type of acyl acceptors used and oil to acyl acceptor molar ratio were studied. Ethyl acetate gave better results in comparison with methanol as acyl acceptor. A maximum conversion of 33.3% was obtained when ethyl acetate was used, at a molar ratio of 1:11 and catalyst concentration 10 (w/w) % of oil after 24hours. In case of methanol, maximum conversion was 31% at a molar ratio of 1:4 and catalyst concentration of 15(w/w) % of oil after 48hours. Variation in pH did not show any significant change in percentage of conversion.

对含有高游离脂肪酸（FFA 26％）的非食用橡胶种子油生产生物柴油进行了研究。使用游离粉末形式的Rhizopus Oryzae脂肪酶作为催化剂。研究了反应参数如催化剂浓度，反应时间，反应混合物的pH值，酰基受体的类型和油对酰基受体摩尔比的影响。与甲醇作为酰基受体相比，乙酸乙酯的结果更好。当使用乙酸乙酯时，以1:11的摩尔比和24小时后油的催化剂浓度10（w / w）％获得最大转化率33.3％。在甲醇的情况下，48小时后，摩尔比为1：4和催化剂浓度为15（w / w）％的油的最大转化率为31％。 pH的变化没有显示转化率的任何显着变化。
