Abstract

Catalytic cracking dan hydroprocessing merupakan dua proses yang digunakan untuk mengubah minyak nabati menjadi biofuel, gabungan dari kedua proses tersebut dinamakan reaksi hydrocracking. Minyak bintaro yang bersifat non-edibleoil serta memiliki kadar minyak cukup banyak yakni sebesar 35-50% dapat direkomendasikan sebagai salah satu sumber minyak nabati yang dapat diolah menjadi biogasoil. Penambahan logam nikel (Ni) dan tembaga (Cu) ialah untuk memperoleh yield yang lebih baik daripada menggunakan satu jenis katalis. Preparasi katalis dilakukan dengan menggunakan metode incipient wetness impregnation. Variabel loading support HZSM-5 yang digunakan sebesar 5% dan 10%, serta ratio logam Ni-Cu yaitu 1:1. Katalis Ni-Cu/HZSM-5 dianalisa menggunakan BET, EDX, dan XRD untuk mengetahui karakteristik katalis. Selanjutnya proses hydrocracking dilakukan dengan mencampurkan 2 gram katalis Ni- Cu/HZSM-5 dan 250 ml minyak bintaro ke dalam reaktor batch berpengaduk pada suhu reaksi 375 ̊C selama 2 jam. Produk cair (biofuel) yang dihasilkan dari proses hydrocracking dianalisa menggunakan GC-MS untuk mengetahui komposisi hidrokarbon. Rute reaksi yang mendominasi dalam penelitian ini ialah reaksi dekarbinolasi dan dekarboksilasi. Hal itu terlihat dari komposisi hidrokarbon terbanyak dari produk biogsoil yang dihasilkan ialah C15 dan C17. Hasil dari penelitian diperoleh Ni-Cu/HZSM-5 dengan loading 5% dan ratio logam 1:1 optimum digunakan pada proses hydrocracking minyak bintaro untuk menghasilkan biogasoil dengan yield sebesar 82,7%.

Abstract

Studies on hydrocracking of nyamplung oil into biofuel have been studied using the HZSM-5 catalyst. The HZSM-5 catalyst was modified into HZSM-5 mesopore and impregnated using transition metals namely Cobalt, Nickel and Cuprum with a metal loading of 5% and a metal ratio ratio of 1:1:1. The resulting catalyst was then characterized using X-Ray Difraction (XRD), Brunauer Emmet Teller (BET), and Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX). The hydrocracking process was carried out in a batch reactor by adding 0.5 grams of catalyst and a volume of Nyamplung oil of 15 mL. The temperaturs used vary from 250, 300, and 350 oC with a hydrogen gas pressure of 20 bar, and a reaction time of 2 hours. The resulting biofuel product is analyzed using Gas Chromatography Mass Spectrometry (GC-MS). The resulting biofuel product has a compound composition of n-paraffin with an area % of 26.72%, cycloparaffin 3.34%, olefin 0.33%, aromatic compounds 15.83% and polycyclic aromatics 12.56%, with a conversion of 72.1% in temperatur 350 oC. Biofuel from nyamplung oil can be used as an alternative fuel to reduce dependence on fossil fuels through the hydrocracking process.

Abstract

Desilication/alkaline treatment and metal impregnation were used to create the HZSM-5 catalyst supported by Co-Ni. These catalysts' isotherm patterns combined type I and type IV isotherms. This isotherm pattern showed a hysteresis loop at comparatively higher pressures. The pore size distribution of the mesoporous HZSM-5 catalysts was situated between 6 and 12 nm in size. Its use in the hydrocracking of Reutealis trisperma (Blanco) airy shaw oil (RTO) to produce biofuel was investigated. The results of the catalytic test showed that the hydrocarbon makeup of the biofuel was comparable to that of fuel. In comparison to HZSM-5, the mesoporous Co-Ni/HZSM-5 catalyst enhanced n-paraffin by 46.32 area% and aromatic by 34.18 area% in the hydrocracking of RTO.
