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

Abstract

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.
