Studies of biodiesel production using various blends of waste palm cooking oil and castor oil
This study has been conducted using blends of castor oil (CO) and waste palm cooking oil (WPCO) in different proportions to enhance % yield of biodiesel via transesterification. The effects of various blending ratios of WPCO: CO (wt.%), molar ratios of methanol: oil, catalyst concentrations (wt.%),...

| Summary: | This study has been conducted using blends of castor oil (CO) and waste palm cooking oil (WPCO) in different proportions to enhance % yield of biodiesel via transesterification. The effects of various blending ratios of WPCO: CO (wt.%), molar ratios of methanol: oil, catalyst concentrations (wt.%), reaction time, reaction temperature and various co-solvents have been investigated to determine the optimal conditions for transesterification reaction. Maximum % yield of biodiesel is obtained at 75:25 (wt.%) of WPCO:CO blend, 9:1 methanol to oil ratio, 1 wt.% KOH catalyst, reaction temperature of 32°C, reaction time of 30 min, using n-hexane as co-solvent. The highest obtained biodiesel yield is 96%. Analysis confirmed 25 FAME components, and the fuel met ASTM standards. Blending non-edible feedstocks for biodiesel production is a sustainable approach to reduce costs and environmental impact. |
