ABSTRACT
The influence of transesterification conversion was investigated with molar ratio of methanol to rapeoil, water content, dissociative fatty acid value and the life of catalyst using sodium hydroxide, solid alkali nanocrystaline Mg-Al hydrotalcite and immobilized lipase of Candida sp. 99-125 as catalyst. The results showed that the best molar ratio of rape oil to methanol was just 4 : 1 using immobilized lipase of Candida sp. 99-125 as catalyst and the influence of amount of fatty acid to transesterification conversion was small. Using NaOH as catalyst, water have no influence in transesterification conversion. The time was the shortest when using Nanocrystaline Mg-Al Hydrotalcite as catalysts and the life of catalyst was the longest. The quality of obtained under the optimum conditions was up to Germany standard for bio-diesel and easy separated.
