PEMANFAATAN OLI BEKAS SEBAGAI BAHAN BAKU PEMBUATAN BAHAN BAKAR CAIR (BBC) DENGAN METODE CATALYTIC CRACKING MENGGUNAKAN KATALIS MORDENITE

Abstract

Number of vehicles is increasing year by year. Along with that, lubrication oil waste is also increasing. Emerge an idea to process those lubrication oil waste become a beneficial product in use and price with consideration of contents in lubrication oil which is heavy hydrocarbon. Lubrication oil waste turns into liquid fuel by catalytic cracking method with Mordenite as a catalyst. This process was done by breaking heavy hydrocarbon chain into light hydrocarbon through heating using furnace with high temperature above 250oC. Lubrication oil waste put into reactor separated by glasswool so that the catalyst would not mingled with oil waste. Gas produced being condensed to gain liquid biofuel. The highest yield obtain from cracking process on temperature 541,4oC and using 1,5 gram of catalyst both for lubrication oil waste from motorcycle and car. The results from difractogram Gas Chromatography analysis shows that produced liquid fuel has similar composition with gasoline.
