用载铂HY沸石作催化剂进行了间二甲苯异构化反应,与未载铂的HY沸石比较、其对二甲苯的选择性有明显提高.经NH_3 TPD法证实载铂后总酸度、酸强度降低,说明载铂HY的酸性和择形度有利于对二甲苯的生成,研究了该反应的脉冲反应动力学.
The meta-xylene isomerization reaction was carried out using platinum HY zeolite as catalyst, and the selectivity to p-xylene was obviously improved compared with that of HY zeolite without platinum. The total acidity, acid strength Reduce, indicating that the acidity and shape selectivity of platinum HY is conducive to the generation of p-xylene, the reaction pulse reaction kinetics.
