在经ＳｉＣｌ４化学液相沉积的ＨＺＳＭ５沸石催化剂上进行了甲苯歧化、Ｃ６烷烃异构体催化裂解和邻二甲苯异构化反应．随着ＳｉＯ２沉积量增加，沸石内表面性质变化不大，而孔径逐渐缩小，甲苯歧化和邻二甲苯异构化反应的对二甲苯选择性提高，Ｃ６烷烃异构体中支链烃３甲基戊烷和２，２二甲基丁烷的裂解反应转化率下降．实验结果表明，化学液相沉积是改善沸石催化剂对反应物和产物择形性能的一种有效方法． Toluene disproportionation, catalytic cracking of C6 alkane isomers and o-xylene isomerization were carried out on HZSM5 zeolite catalyst deposited by chemical liquid deposition of SiCl4. With the increase of SiO2 deposition, the inner surface properties of the zeolites did not change much, but the pore size gradually decreased. The selectivity of p-xylene for toluene disproportionation and ortho-xylene isomerization was increased. In the C6 alkane isomers, The conversion of pentane and 2,2-dimethylbutane decreases. The experimental results show that chemical liquid deposition is an effective method to improve the shape selectivity of reactants and products by zeolite catalysts.
