Abstract

Biofuel from vegetable oil becomes one of the most suitable and logical alternatives to replace fossil fuel. The research focused on various metal ratio Zinc/Molybdenum/HZSM-5 (Zn-Mo/HZSM-5) catalyst to produce liquid hydrocarbon via catalytic hydrocracking of Ceiba penandra oil. The catalytic hydrocracking process has been applied in this study to crack Ceiba pentandra oil into a gasoil range hydrocarbon using Zn-Mo/HZSM-5 as a catalyst. The effect of various reaction temperature on the catalytic hydrocracking of Ceiba pentandra oil were studied. The Zn-Mo/HZSM-5 catalyst with metal ratio was prepared by incipient wetness impregnation method. This process used slurry pressure batch reactor with a mechanical stirrer. A series of experiments were carried out in the temperature range from 300-400 oC for 2 h at pressure between 10-15 bar. The conversion and selectivity were estimated. The liquid hydrocarbon product were identified to gasoline, kerosene, and gas oil. The results show that the use of Zn-Mo/HZSM-5 can produce gas oil as the most component in the product. Overall, the highest conversion and selectivity of gas oil range hydrocarbon was obtained when the ZnMo/HZSM-5 metal ratio was Zn(2.86 wt.%)-Mo(5.32 wt.%)/HZSM-5 and the name is Zn-Mo/HZSM-5_102. The highest conversion was obtained at 63.31 % and n-paraffin (gas oil range) selectivity was obtained at 90.75 % at a temperature of 400 oC. Ceiba pentandra oil can be recommended as the source of inedible vegetable oil to produce gasoil as an environmentally friendly transportation fuel.

Abstract

In this study, hydrocracking of coconut oil over Ni-Fe/HZSM-5 catalyst was carried out in a batch reactor under different reaction temperature. Coconut oil is proposed as one of the potential feedstock for biofuel production. The Ni-Fe/HZSM-5 catalyst was prepared by incipient wetness impregnation method. The characterization of Ni-Fe/HZSM-5 catalyst by X-Ray Diffraction (XRD), Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDAX), and Brunauer-Emmett-Teller (BET). The chemical composition of biofuel was analyzed by Gas-Chromatography-Mass Spectrometry (GC-MS). The results from the GC-MS analysis showed that the hydrocracking reaction over 10 % (Ni-Fe)/HZSM-5 catalyst at temperature of 375 oC obtained the highest hydrocarbon content (contained 49.4% n-paraffin, 26.93 % isoparaffin, 3.58 % olefin) and the highest yield of bio-gasoil 38.6 % in the biofuel liquid hydrocarbon. Pentadecane (n-C15) and heptadecane (n-C17) were the most abundant hydrocarbon compounds in biofuel liquid hydrocarbon. Decarboxylation and/or decarbonylation was the dominant reaction pathways in this process. Based on the result, the reaction temperature had a significant effect on the distribution of biofuel composition and yield of biofuel from coconut oil.
