摘要
采用综合改性法对 HZSM- 5沸石进行改性处理 ,在脉冲 -在线装置对改性催化剂进行了评价 .试验表明 ,经水热处理与稀土改性相结合所得的 HZSM- 5沸石对 C1 2 烷烃的裂化有着良好的催化性能 .
ZSM 5 zeolite catalysts are increasingly used in catalytic cracking process due to domestic demands for gasoline octane number. The catalytic performances of nanomter ZSM 5 zeolites used as additive catalysts have been investigated in micro pulse reactor combined with a GC. By combination hydrothermal of treatment and La 2O 3 modification, an excellent catalyst can be made, which shows that ZSM 5 zeolites have great advantages in improving the gasoline octane number, and in the catalytic cracking process.
