- Abstract
- Waste oyster shell as catalysts for transesterification of soybean oil was investigated to produce the bio-diesel oil. Theexperimental conditions included molar ratios of the methanol to oil (6:1, 9:1, 12:1 and 15:1), the concentration of catalystused (5, 10, 15, and 20wt%), the reaction temperatures (50, 60 and 70oC), and calcination temperature of oyster shell(800, 900 and 1,000oC). The experimental results showed that the conversion of soybean oil increased with the methanolmixing ratio and with the reaction temperature. The conversion was increased with the concentration of catalyst, butslightly decreased over 20wt.%. A 12:1 molar ratio of methanol to oil, addition of 15% oyster shell catalyst, 900oCcalcination temperature of oyster shell, and 60oC reaction temperature gave the best results. The Fatty Acid Methyl Ester(FAME) conversion exceeded 94% at 1 h.
