摘要
在对HZSM-5作高温水蒸气处理的基础上,以Sb_2O改性,全面考察改性前后分子筛催化剂的表面性能,二甲苯异构化反应及其对甲苯乙醇乙基化反应的活性和对位选择性的影响。
After treated with high temperature steam HZSM-5 was modified with antimony. A thorough investigation was made for surface properties of the molecular sieve catalysts before and after modification , isomerization of xylene and its influences on activity of ethanol ethylation and para-position selectivity.
