Abstract

The physicochemical properties of catalysts synthesized from zeolites of the BEA and MWW framework types using pseudoboehmite as a binder and their catalytic activity in benzene alkylation with propylene in the gas-phase and liquid-phase modes have been studied. It has been found that the MWW-based catalyst is characterized by stronger acidity in terms of both amount and strength of acid sites; however, the catalytic activity of this sample is inferior to that of zeolite BEA. The observed effect is attributed to the higher accessibility of acid sites in the three-dimensional system of zeolite BEA. With respect to some parameters, such as cumene selectivity and on-stream stability, zeolite MWW is superior to zeolite BEA; the difference is attributed to the structural features of these zeolites.
