Abstract

Research has been carried out on acid zeolite to break long carbon chain bonds into shorter ones using acid zeolite. The catalyst used is made from zeolite which is treated with calcination with nitrogen at a temperature of 400 oC for 2 hours then followed by hydrothermal treatment at a temperature of 500 oC for 2 hours and then impregnation with Ni metal, then oxidation with oxygen for 3 hours. at a temperature of 500 oC. Then the cracking process was carried out on the methyl oleate compound with a zeolite catalyst impregnated with Ni metal using a Fluid Bed reactor operated at a temperature of 500 oC for 30 minutes while hydrogen gas was flowing at a speed of 10 mL/minute. The results obtained are that based on analysis using GCMS are as follows: the process of breaking down alkane compounds obtained from the interaction between the catalyst surface in the upper layer can interact again with the catalyst surface in the lower layer, in line with the feed flow. This interaction may result in shorter alkane compounds and other forms of compounds such as cyclic, aromatic or isomeric forms
