Abstract

Electrolysis method is one of the newest method recently used for biodiesel production. It is hoped that the use of electrode may minimise energy usage in the process for producing biodiesel. In this research, electrolysis process has been tested using raw materials of crude palm oil (CPO) and waste cooking oil (WCO). Methanol is used as solvent with volumetric ratio of 12:1 to raw material, with catalyst of NaOH and KOH. Stirring is employed to quicken the contact between raw materials and the electrodes. The distance between the two electrodes is 15 mm. Electrolysis is started by stirring the mixture at 500 rpm for 2 hours with electrical voltage varied at 14 V, 16 V, 18 V, 20 V, and 24 V. By the use of this method, biodiesel with best quality has been found from raw material of WCO with maximal conversion of 98.6% and highest yield of 90.26%. This result is achieved at condition of 18 V with catalyst of KOH. According to Faraday laws, current density is proportional to the amount product from anode or cathode. Yet, this also depends on the space between the two electrodes. As conclusion, electrolysis method may make transesterification reaction between triglyceride and methanol to occur which gives yield to biodiesel product with high conversion.
