Biodiesel production from fat of tra catfish by KOH/γ- Al2O3 as a solid-base catalyst.

Abstract

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 550oC 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 60oC 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
