Abstract

This work deals with the dealumination of zeolite beta under different conditions to optimize its catalytic performance The dealumination was carried out either using oxalic or tartaric acid solution of different pH values or steaming up to 500 °C The dealuminated zeolite samples were characterized using Xray diffraction N2physisorption ICP 27Al NMR and NH3TPD Their catalytic activities were studied for acylation reaction of 2methoxy naphthalene or naphthalene with acetic anhydride and esterification of benzyl alcohol with hexanoic acid Among the dealuminated samples examined those treated with oxalic acid or tartaric acid at pH 2 showed high activity The high activity can be correlated with the relative increase in the amount of strong acid sites and with the enhanced accessibility of the reactants to the active sites which are caused by removal of extraframework Al species on the acid treatments
