Biodiesel from Pyrolysis Fatty Acid Methyl Ester (FAME) using Fly Ash as a Catalyst

Biodiesel is an environmentally acceptable alternative fuel that has no negative health effects and may be used in vehicles to cut emissions when compared to regular oil. Biodiesel can be produced from the pyrolysis process of Fatty Acid Methyl Ester (FAME) using a fly ash catalyst. The purpose of this study was to obtain biodiesel with a low water content of hygroscopic nature. The pyrolysis process using fly ash catalyst occurs in a temperature range of 141200C, which has an initial boiling point (IBP) of 151C. The results showed that the characteristics of the biodiesel produced were following the standards of the Director General of Oil and Gas, namely density 842,500847,500 kg/m, viscosity 3.053-3,371 cSt, CCI of 48.7-49.7C at 181-200C, flash point 58-59C, content water 223218 ppm, and sulphur content of 700 ppm.
