摘要
采用NH3-TPD、XRF、烷基化反应等手段研究了铵离子交换对β沸石酸性的影响。结果表明,随着交换度的增加,β沸石产生了更多的酸中心,对苯和丙烯烷基化反应的催化活性提高。
The effects of ammonium exchange on the acidity of zeolite β were investigated using NH3-TPD, XRF and alkylation reaction. The results showed that the acidity of zeolite β increased with the ion exchanged degree of ammonium. The result of the alkylation reaction of benzene with propene indicated that the convention of benzene after treatment was higher than that before treatment.
