Analysis of The Ratio Catalys Promoters BaO/CaO to Methyl Ester Content and Yield in Biodiesel Using Electrocatalytic Reactor

The efficiency of biodiesel production from vegetable oils needs to be developed. process transesterification using heterogeneous catalysts has been widely studied replace the role homogeneous catalysts. use BaO promoters into metal oxides increases activity in reactions. This study was conducted provide information about effect concentrations that are filtered calcium oxide (CaO) on reaction tofu pulp oil methyl ester electrocatalytic methods. at room temperature with a voltage 18.5 Volts and time 120 minutes. Methanol ratio: is used 10:1 Tetra Hydro Furan (THF) as co-solvent. carried out graphite electrodes. research variables concentration 2%, 4%, 8%. parameter test content obtained results reactions chromatography gas analysis (GC-MS). In this study, BaO/CaO catalyst impregnated by wet method calcined 450oC for 180 From experiments highest yield bao / cao 2% 99.99% 94%.
