BIODIESEL FROM FAT OF TRA CATFISH VIA KOH/γ-Al2O3 CATALYST

Abstract

In the present study, the methanolysis of tra fat using KOH/γ-Al₂O₃ as heterogenous catalyst was performed with the help of low frequency ultrasonic processor (20 kHz). The main object of this study was to investigate the influences of parameters like methanol to fat molar ratio, catalyst concentration, time and temperature of reaction, wave amplitudes, and energy input on the yield of biodiesel. Moreover, this research also examined the influences of ultrasonic wave on the fatty acid composition and the properties of KOH/γ-Al₂O₃ catalyst.
