Synthesis and characterization of Co-B/Al-SBA-15 for ethylene hydropolymerization

In this paper, 0.6%B-10%Co/Al-SBA-15 was used as catalyst for hydropolymerization of ethylene at low temperature and medium pressure. Remarkable performance was shown in process that Ethylene, CO and H2 were transformed into liquid fuel. Especially, liquid fuel occupied a large proportion of products. For productivity and characteristic evaluation purposes, three ratios of Si/Al (20; 40 and 60) were selected for research on Al-SBA-15. Al-SBA-15 with ratio of Si/Al= 40 was found to be the most suitable sample for continuous impregnation of Co with four ratios 5.0%Co/Al-SBA-15, 7.5%Co/Al-SBA-15, 10%Co/Al-SBA-15, 15%Co/Al-SBA-15 respectively. For catalyst advancement,  B was added to 10%Co/Al-SBA-15 with a ratio of 0.6%.  As experiment result, 10%Co-0.6%B/Al-SBA-15 is the most satisfactory sample catalyst in the research that should be used as catalyst for hydropolymerization process of Ethylene.
