Abstract

Membrane reactor is an alternative technology that is used in the manufacture of biodiesel, one of the advantages that the reaction and separation process takes place in a single stage simultaneous. This research aims to study the effect of the variation of the catalyst and mole ratio feed CPO off grade - methanol in biodiesel production, a pretreatment process performed on the raw materials that aim to reduce the FFA content CPO off grade, the results obtained pretreatment FFA content of 0.79%, then performed transesterification process which was held in a membrane reactor with a variation of the mole ratio of CPO off grade -methanol 1:12, 1:18, and 1:24, the concentration of the base catalyst 1% -wt, 1.5% -wt and 2% -wt, pressure transmembrane 2 bar and a temperature of 60 oC process. The results showed biodiesel production using membrane reactor reached 72.02% yield on the condition of the mole ratio of 1:18 with a concentration of 2 %-wt, characteristics of biodiesel produced meets the quality standards of biodiesel in Indonesia including biodiesel, densityis 860-884 kg/m3, viscosity of biodiesel is 5.14 to 5.76 mm2/s, Flash Point is 158-161 °C, Acid Numberis 0.62 to 0.75 mg-KOH/g.Keywords: biodiesel, CPO off grade, membrane reactor, mol ratio, catalyst concentration.
