ALKYLATION OF COKING BENZENE WITH ETHANOL OVER NANOSCALE HZSM-5 ZEOLITES: EFFECT OF CALCINATION ON CATALYTIC STABILITY

摘要

Calcination after hydrothermal treatment obviously weakens the acidity and enlarges the pore size of the nanoscale HZSM-5 zeolites, therefore, improves their catalytic stability during the gas-phase alkylation of coking benzene with ethanol.
