| Abstract: | Four kinds of dealuminated Y zeolite catalysts were prepared by various dealumination methods. Their physicochemical properties were characterized by NH 3 TPD, nitrogen adsorption at low temperature and XRD, and reactivities of alkylation of benzene with 1 dodecene were investigated over these catalysts. It was found that the catalytic activity, selectivity and stability in this reaction are influenced substantially by both acidity and pore structure of the catalysts. |
