【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.更多还原
