PENGARUH SUHU KALSINASI PADA SINTESIS KATALIS PADAT TITANIUM DIOKSIDA TERSULFONASI TERHADAP KONVERSI PEMBENTUKAN ESTER PADA REAKSI ESTERIFIKASI DESTILAT ASAM LEMAK MINYAK SAWIT MENGGUNAKAN METANOL

Abstract

Solid catalyst synthesis has been carried out, including sulfonated titanium dioxide catalysts and their
derivatives. These catalysts can be used to help the reaction to biodiesel production. However, information about the
catalyst synthesis processed related to the calcination temperature and its effect on the conversion to biodiesel formation
is very rarely found. This study aims to investigate the effect of calcination temperature on the catalyst synthesis process
so that it can be useful in determining the right calcination temperature in the synthesis of sulfonated titanium dioxide
catalysts and their derivatives. Catalyst synthesis using impregnation method and testing for catalytic effects were carried
out on the chemical reaction of esterification of fatty acids contained in fatty acid distillates from palm oil (PFAD). The
results showed that the catalyst synthesized at 500 0C calcinations gave the best catalytic effect, where the conversion to
methyl ester formation was 98.1% with physical properties including density and viscosity at 40 0C in accordance with
SNI standards for biodiesel.
