Abstract

BIODIESEL PRODUCTION FROM FAT OF TRA CATFISH
BY KOH/γ-Al₂O₃ AS A SOLID-BASE CATALYST

The objective of the project is to research the production of biodiesel from fat of Tra Catfish and methanol using K⁺/γ-Al₂O₃ as a solid-base catalyst. The results show that KOH/γ-Al₂O₃ prepared by loading KOH of 7 mmol on Al(OH)₃ of 1 g, after being calcined at 550^oC for 2 h, which can give the best catalytic activity for this reaction. The maximum conversion of 92,63% has been achieved after 90 minutes, at 60^oC when the molar ratio of MeOH to tra fat is 8/1 and 6% KOH/γ-Al₂O₃ catalyst. The produced biodiesel met the required ASTM D6751 standard.
