Ru助剂对Co/SiO2/HZSM-5催化剂合成航空燃油类烃的影响
Ru modified Co/SiO2/HZSM-5 catalysts for jet fuel-range hydrocarbons synthesis
摘要
Abstract
Selective synthesis of jet fuel-range hydrocarbons ( C8~18 ) was investigated in a fixed-bed reactor over Ru modified cobalt-based catalysts, supported on mesoporous SiO2 and microporous HZSM-5. The effect of Ru adding amount ( 1% ~4%) and the textual and structural properties of the catalysts on Fischer-Tropsch synthesis ( FTS ) performance were studied. The results showed that the tailor-made Ru-Co/SiO2/HZSM-5 catalysts maintained both meso-and micro-pores. Co dispersion and reducibility at 150~750℃ were enhanced with the increase of Ru amount, which resulted in the increase of CO conversion. In the same time, the yield of iso-paraffins was enhanced due to the existence of microporous structure of HZSM-5 . Thus CO conversion of 62. 8% and yield of jet fuel-range hydrocarbons ( C8~18 ) of 37. 7 %, including 10. 9% of iso-paraffins, were achieved over 1% Ru modified Co/SiO2/HZSM-5. The FTS product distribution shifted to low-carbon hydrocarbons when Ru amount was higher than 2% due to the increased CO hydrogenation rate and CH4 selectivity.关键词
