正己烷在Cu改性ZSM-5上的芳构化反应

本文研究了正己烷在Cu改性ZSM-5上的芳构化反应。发现引入适量的Cu可提高芳构化反应的选择性和芳烃收率，考察了催化性能与酸性的关系。Cu的引入使ZSM－5沸石的L酸量增加，B酸量减少，芳构化性能增强。提出了B酸和L酸中心的协同效应对芳构化反应的促进作用。

Aromatization of n-Hexane over Ni-Modified ZSM-5

The aromatization of n-hexane over Cu-modified ZSM-5 was studied. It was found that the selectivity to aromatization and the yield of aromatics have increased by adding some amount of Cu into ZSM-5. The investigation of the relationship of the catalytic function with the acidic properties of the catalyst was made. It appeared that Bronsted acidity decreased, and Lewis acidity increased by introducing Ni into the catalyst, which is likely to be responsible for the increase of aromatization activity. It was proposed that the good effect for n-hexane aromatization was attributed to the cooperation functions of both Bronsted and Lewis acids.
