摘要

分别考察了异丙醇、异丁醇和异戊醇对2.0% La/HZSM-5催化乙醇脱水制乙烯反应的影响，结合NH3-TPD、BET、TG等催化剂表征结果，对杂醇的影响机理进行了深入分析。研究表明，所考察的3种杂醇在2.0% La/HZSM-5作用下均能发生脱水反应生成诸多易聚合的烯烃类产物，对其催化乙醇脱水的性能产生了明显的影响；而且随着加入杂醇的碳原子数的增加，催化剂的积炭情况逐渐加重，催化性能也有明显下降的趋势。2.0%La/HZSM-5与HZSM-5原粉相比，具有较大的比表面、孔容和表面酸量，拥有强度更强的弱酸中心和强度较弱的强酸中心，催化含杂醇的乙醇脱水制乙烯反应时其催化性能和抗积炭能力得到了明显提升。

Abstract

The effects of isopropanol

isobutyl alcohol and isoamyl alcohol on the ethanol dehydration to ethylene catalyzed by 2.0% La/HZSM-5 were investigated.With the characterization of NH3-TPD

BET and TG

the reaction mechanism was analyzed.The three fusel alcohols can result in dehydration

and produce olefin products that are easily polymerized.These products have significant effects on the performance of the catalyst.The coke on the catalyst is aggravated as the number of carbon atoms in the fusel increases

so that the catalytic performance is worse.Compared with HZSM-5

2.0%La/HZSM-5 has larger surface area and pore volume

more surface acid

stronger weak acid centers

and weaker strong acid centers

presenting better catalytic performance.
