沸石的改性是提高沸石择形催化性能的重要手段.因此,沸石的改性及改质剂作用机理的研究,受到人们的关注.本文采用浸渍法制得了非骨架含硼的催化剂,在沸石合成中引入硼得到了骨架含硼的催化剂,用高温硼酸水溶液处理制得了脱铝沸石中含硼的催化剂.用XRD,IR,TPD等对它们进行了表征.研究了硼在沸石中所处的状况及其对择形催化反应性能的影响.采用的探针反应为甲苯/乙醇烷基化反应.对于骨架含硼
Zeolite modification is an important means to improve zeolite shape-selective catalytic performance.Therefore, the modification of zeolite and the research on mechanism of modifier attract people’s attention.In this paper, non-framework boron-containing catalyst was prepared by impregnation method, The boron-containing catalyst was obtained by introducing boron into the zeolite, and the catalyst containing boron in the dealuminated zeolite was obtained by treating with boric acid in high temperature.The catalysts were characterized by XRD, IR, TPD and so on.The boron in zeolite And its effect on the shape-selective catalytic reaction.The probe reaction used was toluene / ethanol alkylation reaction.For the skeleton containing boron
