| Abstract: | HZSM-5 zelolites with different Si/Al ratios(25,38,50),nano-scale HZSM-5,and the modified HZSM-5 were used in the synthesis of ethylbenzene by the alkylation of benzene with ethanol.And the activity,selectivity and desulphurization effect of the zeolites were studied.The results show that the lower the Si/Al ratio the higher the activity,and the better the desulphurization effect.The nano-scale HZSM-5 and B-HZSM-5 have higher activity,selectivity and longer operation life. |
