The effect of operation conditions on aromatization property of the tin-modified HZSM-5 catalyst

75 ~ 120 ℃ Of FCC light gasoline fraction was used as raw material,different preparation methods on aromatization property of the tin-modified HZSM-5 catalyst were researched in a small fixed bed reactor,and the effects of reaction temperature and reaction pressure on the aromatization process were studied.The results showed that the stability of HCl-Sn/HZSM-5 catalyst was the best.The best reaction condition is as follows liquid hourly space velocity(LHSV) is 1.0 h-1,the reaction temperature was 550 ℃,reaction pressure is 0.3 MPa.Under optimum reaction condition,the total content of aromatics was 92.88%,olefins and alkanes conversion rates were 93.93% and 89.97%,respectively.
