Abstract
An aluminosilicate molecular sieve catalyst, its preparation and application thereof are provided. The catalyst shows a desorption curve having three peaks P1, P2 and P3 in its NH-TPD pattern. The desorption temperatures corresponding to the summits of the three peaks P1, P2 and P3 are respectively in a range of 180-220° C., 250-290° C. and 370-410° C. The catalyst shows a higher activity, selectivity and stability when used for producing alkylaromatic hydrocarbons by gas-phase alkylation of aromatics with olefins.
