Biodiesel production from waste cooking oil in presence of modified waste eggshell catalyst via microwave heating Conference Paper uri icon

abstract

  • Abstract. This study compares the efficiency of producing biodiesel from waste cooking oil (WCO) utilizing modified eggshell based calcium oxide (CaO) catalysts improved with magnesium-aluminum hydrotalcite to pure eggshell based CaO by microwave-heated transesterification. The study optimized process parameters for a methanol to oil molar ratio of 9:1 at 65°C for 30 minutes, with the goal of enhancing catalyst stability and basicity for effective biodiesel synthesis. The study demonstrated that the eggshell based CaO/Mg-Al catalyst was better in biodiesel yield (89.44%) than the pure eggshell based CaO and exhibited improved stability and catalytic activity through gas chromatography with mass spectrometry (GC-MS) analysis for fatty acid methyl ester (FAME) composition and biodiesel yield.
