摘　　要：用不同脱铝方法制备了 4种脱铝 Y沸石催化剂 ,并利用 NH3-TPD、低温 N2 吸附以及 XRD技术对其物化性质进行了测定 ,并考察了其在苯与 1 -十二烯烷基化反应中的催化性能 ,揭示了脱铝 Y沸石的酸量。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.
