Abstract

The purpose of this study is to determine the effect of operating temperatures on biodiesel production from Palm Fatty Acid Distillate (PFAD) by using Amberlyst DPT 2 UPS catalyst. Amberlyst DPT 2 UPS catalyst is a heterogeneous catalyst whose performance is strongly influenced by operating temperature. In this study, Amberlyst DPT 2 UPS catalyzes the reaction between PFAD and methanol. The molar ratio of PFAD to methanol is 1: 5, and the reaction time is 8 hours. Operating temperature variations performed are 120°C, 125°C, 130°C and 135°C. Analysis carried out in the study included analysis of acid value, flash point, kinematic viscosity, density, and composition of biodiesel. The acid value, the flash point, the kinematic viscosity, the density, and the biodiesel composition is analyzed by the ASTM Standards. The results showed that the highest conversion of 99.85% is obtained at an operating temperature of 130°C, while the analysis results of acid values, flash points, kinematic viscosity, and densities have met the ASTM standard for all variations in operating temperature.
