In this work, used palm oil was reacted via cracking over mechanically mixed catalysts between ZSM - 5 and Y - Re - 16 to generate organic liquid products ( OLP ). The catalysts used were known for high acidity and low cost for decomposition, degradation, and deoxygenation of triglycerides . The cracking experiments were conducted in a flow reactor . The experimental variables included reaction temperature between 300 - 500 ° C, catalyst loading between 5 - 20 % w / w, and ratio of mixed catalyst between ZSM - 5 and Y - Re - 16 from 0 - 100 % w / w . They were set via response surface methodology and central composite design of experiments . Both catalysts showed good cracking reaction . The optimum condition for generating the OLP of about 85 % w / w was found at 300 ° C, 5 % catalyst loading, 97 % ratio of mixed catalyst . The OLPs with different short - chain hydrocarbons between C 7 - C 21 were identified . The main components were 71 . 43 % of diesel, 12 . 11 % of gasoline, and 8 . 95 % of kerosene - like components . }, pages = {159--166} doi = {10.14710/ijred.9.2.159-166}, url = {https://ejournal.undip.ac.id/index.php/ijred/article/view/27747} }
