Perengkahan PFAD (Palm Fatty Acid Distillate) Dengan Katalis Zeolit Sintesis Untuk Menghasilkan Biofuel

Abstract

Palm Fatty Acid Distillate (PFAD) is a by-product of the manufacture of cooking oil. The PFAD has a high potential to be used as raw material for biofuel by catalytic cracking because it is a long-chain hydrocarbon. This research aims to study the influence of time and temperature conversion reaction to catalytic cracking reaction using zeolite catalyst synthesis. The PFAD cracking was taken place in a batch stirred tank reactor at the temperature of 240, 260, 280, 300oC for 60, 80, 100, 120 minutes. The changes in functional groups of cracking products were analyzed using FTIR (Fourier Transform Infra Red), while the analysis of components contained in the product was conducted using GCMS (Gas Chromatography Mass Spectra) analysis. The highest reaction conversion result (98.7%) was obtained at a temperature of 280oC and the reaction time of 100 minutes. The cracking process did not produce biofuels, but the compounds formed were in the form of tridecanoic acid (C13H26NO2), Cholest-8-en-3-ol (C28H48O) and methyl vinyl ketone (C4H6O).
