Abstract

Liquid fuel, a mixture of ethylene’s liquid oligomer, from ethylene was successfully carried out by oligomerization of ethylene in the presence of Co/Al-SBA-15. The mesoporous Co/Al-SBA-15 catalyst was prepared through impregnation of varies amount of Co (5, 7.5, 10, and 15 wt.%) into Al-SBA-15. The conversion of ethylene was performed at atmospheric pressure and 190°C in the presence of CO and H₂, and 08 hour/day. Through all of Co impregnated proportion on Al-SBA-15 (5, 7.5, 10 and 15 wt.%), the GC-MS result showed the liquid hydrocarbon were obtained as naptha (15.37÷30.53%), gasoline (10.65÷21.17%), kerosene (1.49÷20.50%) and diesel (3.21÷3.69%) fraction. The highest conversion of ethylene into liquid fuel was found in the presence of 7.5%Co/Al-SBA-15, with the yield of 20%. Byproducts was also obtained during the conversion, e.g. 3,4,5-methylnonane, 2,3 dimethylnonane, 3-methylheptane, and 4-ethylheptane, which was approximately 30% of total product volume.
