Abstract

In the research, catalyst activity of Al-MCM-41 with different ratios of Al/Si are compared by observing catalyst samples that successfully synthesized. The ratio 30 of Al/Si was selected for impregnation process with Co to obtain the formation of 5.0% Co/Al-MCM-41, 7.5% Co/Al-MCM-41, 10% Co/Al-MCM-41, 15% Co/Al-MCM-41 and15% Co/Al-MCM-41. Through experiments, 10% Co/Al-MCM-41 sample was advisable to added with B. for evaluation of metal dispersion on carrier surface. Liquid fuel products were obtained by using . 10% Co-0.6% B/Al-MCM-41 catalyst. Hydropolymerization of ethylene under low temperature (190°C) and normal pressure (1atm) was clearly accelerated by 10% Co-0.6% B/Al-MCM-41. This would be a positive sign for fuel industry to convert ethylene, CO and H₂into valuable products.
