HIGHLY ACTIVE AND STABLE IMMOBILIZED ALUMINIUM CHLORIDE CATALYST FOR ALKYLATION OF BENZENE WITH 1- DODECENE

摘要

An AlCl_3 catalyst immobilized on gamma-Al_2O_3 with meso-and macro-pore bimodal structure was prepared and studied in the alkylation of benzene with 1-dodecene in a suspension bed reactor.The catalyst exhibited high activity,selectivity and stability during 1000 h running,with a 1-dodecene conversion of more than 95%,monoalkylbenzene selectivity of 92%,and 2-phenyldodecane(2-Ph)selectivity of nearly 42%.
