Abstract
Water is the factor need to attend on the esterification to produce biodiesel by enzyme catalysts because of its complicated influences on the catalyst activity and sability of enzyme as well as the productivity of reaction. Some studies conclued that some lipases need to be maintained its proper structure by the certain amount of water. On the other hand, water is the by-product of the ester reaction, hence the high water content exists in the reaction media causes the back forward reaction, consequeces to reduce the yield. Therefore, this study drive to indentify the suitable amount of water for assisting activition of liquid enzyme catalyst, and investigate the using SAP to absorb the produced water. The effect of water content on the enzyme activity was assigned through discussed the efficiency of the esterifiaction with molar ratio of oleic acid to methanol 1:3 at the temperature of 250C, catalyst amount of 10wt% and varied water amount of 0 to 30 wt% (base on the fatty acid mass) for 1 hour and 3 hours. Another rections were carried out with the condition similar to above reactions and added 5% (w/woleic acid) of SAP amount to study the ability of maintaining the esterifiaction. Results illustrated that the conversion was increased obivously from 0% to 95 % with added water content increased from 0 wt% to 30wt%. Meanwhile the conversion rate was improved significant with using SAP, the yield reached to 95% with added water ammount of 10 wt% for only 1 hour.
