Abstract |
ABSTRACT: In this study, the catalytic performance of bimetallic NiW modified ZSM-5 catalysts for hydrocracking conversion of crude palm oil (CPO) is presented. Crystalline ZSM-5 zeolites with precisely controlled SiO2/Al2O3 ratios (SARs) of 30, 50, 70 and 100 were successfully synthesized from kaolin via the hydrothermal method. To enhance their catalytic activity, as-prepared zeolites were modified with Ni, W and NiW by the impregnation technique. The catalysts were characterized by various techniques. The total amount of Ni and W in the catalysts was determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES) technique, and found to be in the range of 3.08-3.16 and 5.88-6.39 wt.%, respectively. These NiW-ZSM-5 catalysts showed good activity for the production of biofuels and their catalytic activity decreased in the order NiW-ZSM-5>Ni-ZSM-5>W-ZSM-5>ZSM-5. The incorporation of NiW improved the production of both hydrogenation and dehydrogenation hydrocarbon compounds. Moreover, the different SARs in ZSM-5 zeolites also affected the catalytic activity and NiW-ZSM-5 with SAR of 50 gave an excellent conversion (96.20 %). Additionally, the types of the obtained hydrocarbon products were identified as gasoline (C5-C10), kerosene (C9-C11) and diesel (C10-C20) by simulated distillation gas chromatography-flame ionization detector (SimDis GC-FID) and gas chromatography-mass spectrometry (GC-MS). |
