AbstractMCM-49 zeolite was alkali-treated with NaOH solutions under mild and severe conditions. The samples before and after alkali-treatment were both used as catalysts in liquid alkylation reaction of benzene with ethylene. XRD, XRF, TPD, TPO, IR, SEM, (29)Si NMR, N(2) adsorption and desorption techniques were employed to characterize the samples. The mildly alkali-treated samples exhibited higher catalytic stability than the parent HMCM-49, as the amorphous particles on the MCM-49 crystal surface were cleaned and the diffusion of the reactant and product was enhanced. The severe alkali-treatment condition resulted in the selective extraction of silicon atoms and the introduction of extra mesopores. The catalytic stability of the catalysts that had been severely alkali-treated was not as good as that of mildly treated ones, but was still better than that of the parent HMCM-49 catalyst if the alkali-treatment conditions were not too severe.
