Abstract

This research is related to the synthesis of SO₄²ˉ/TiO₂ solid catalyst and their application in the production of biodiesel from palm fatty acid distillate (PFAD) through the chemical esterification reaction pathway using ethanol. The focus of the research includes evaluating the effect of sulfuric acid concentration on the catalyst synthesis process with impregnation. The catalytic effect reviewed is the conversion rate of the formation of biodiesel with ethyl ester type,composition and physical properties of biodiesel products. The results showed that TiO₂ powder impregnated using H₂SO₄ with a concentration of 2 M, based on FT-IR instrument analysis had the most complete functional groups such as sulfites, sulfonates, sulfates, and inorganic sulfates, so it was expected to have a better catalytic effect. The catalytic effect test through the PFAD esterification reaction which was carried out during 4 hour reaction time with the reaction temperature of 80ºC, the stirring speed of 250 rpm, and the ethanol/PFAD molar ratio of 13 and the catalyst/PFAD weight ratio of 5% produced biodiesel with 97.7 % conversion and physical properties including density and viscosity inaccordance with the ASTMD-6751 standards.
