| Abstract: | A shape-selective catalyst based on LaZSM5 zeolite with additions of MgO and Al2O3 is prepared for the alkylation of toluene ethylene, resulting into the obvious increase of para-methyl ethylbenzene selectivity. The additions of dilute gases and reaction products into the feed toluene affect obviously the reaction performance. Burning off the carbon using conventional method can regenerate the deactivated catalyst. |
