TRANSESTERIFICATION OF WASTE COOKING OIL ASSISTED BY ULTRASONICATION FOR BIODIESEL PRODUCTION FROM WASTE COOKING OIL USING COPPER DOPED ZINC OXIDE NANOCATALYST

摘要

In this study, copper doped zinc oxide (CZO) were synthesized by wet chemical method. The idea was to use these nanosized particles as catalyst for biodiesel production. Thus, the transesterification reaction of waste cooking oil (WCO) was carried out in an ultrasonicator using copper doped zinc oxide (CZO) nanocatalyst and methanol. Gas chromatography mass spectral detector (GC-MS) was used to identify the fatty acids and fatty acid methyl esters (FAME) present in the WCO and biodiesel respectively. Energy consumption for ultrasonication using CZO nanocatalyst was evaluated and found to be economical. Maximal yield of 86.93% is achieved at optimal condition of transesterification. Gas chromatography mass spectral detector (GC-MS) was used to identify the fatty acids and fatty acid methyl esters (FAME) present in the WCO and biodiesel respectively. Energy consumed for transesterification reaction in ultrasonicator was found out to be economical.
