Abstract
Reaksi deoksigenasi minyak kemiri Sunan menjadi biofuel telah dilkukan dengan katalis ZSM-5. Katalis disintesis dengan variasi mol TPAOH/Al2O3: 1; 2,5; 5; 10; dan 20 untuk mengetahui pengaruh TPAOH sebagai Structure Directing Agent (SDA) pada struktur katalis. Katalis dikarakterisasi dengan XRD dan piridin-FTIR. Hasil XRD menunjukan puncak khas dari ZSM-5 yang menunjukan kristal ZSM-5 telah terbentuk. Hasil uji keasaman menggunakan piridin-FTIR menunjukan bahwa seluruh sampel katalis memiliki sisi asam Lewis dan Brønsted. Uji aktivitas katalitik dilakukan dengan reaksi deoksigenasi minyak kemiri Sunan. Hasil konversi dipengaruhi oleh jumlah sisi asam katalis. ZSM-5 (1 TPA) yang menghasilkan konversi tertinggi yaitu 41,28% juga memiliki sisi asam yang paling besar dibanding variasi lain yaitu sebesar 0,28 mmol/g. Selektivitas hidrokarbon rantai panjang (C11-C18) atau yield diesel yang tertinggi adalah sebesar 98,32% dengan menggunakan katalis ZSM-5 (2,5 TPA). Seluruh katalis memiliki yield diesel di atas 80%, ini menunjukan bahwa seluruh katalis yang dihasilkan dalam penelitian ini memiliki potensi untuk digunakan sebagai katalis dalam reaksi deoksigenasi minyak kemiri Sunan.

Deoxygenation reaction of kemiri Sunan oil into biofuel has been carried out with ZSM-5 catalyst. The catalyst was synthesized with various moles of TPAOH/Al2O3: 1; 2.5; 5; 10; and 20 to determine the effect of TPAOH as a Structure Directing Agent (SDA) on the catalyst structure. The catalyst was characterized by XRD and pyridine-FTIR. The XRD results show a typical peak of ZSM-5 which indicates ZSM-5 crystals have formed. The results of acidity test using pyridine-FTIR showed that all catalyst samples had Lewis and Brønsted acid sides. The catalytic activity test was carried out with the deoxygenation reaction of kemiri Sunan oil. The conversion result is influenced by the number of acid catalyst sites. ZSM-5 (1 TPA) which produced the highest conversion, 41.28%, also had the largest acid site compared to other variations, which was 0.28 mmol/g. The selectivity of long chain hydrocarbons (C11-C18) or the highest yield of diesel is 98.32% obtained using ZSM-5 (2.5 TPA) catalyst. All catalysts have diesel yields above 80%, this shows that all catalysts produced in this study have the potential to be used as catalysts in the deoxygenation reaction of kemiri Sunan oil.
