摘要

芳烃是一种重要的化合物，在燃料中存在芳烃可以提高辛烷值。从理论和工业的角度来看，轻烷烃转化为高价值芳烃是至关重要的。ZSM-5等沸石在轻烷烃的芳构化过程中起着重要作用。本文重点研究了甲烷、乙烷、丙烷、丁烷等轻烷烃及其异构体的芳构化机理。此外，还研究了影响轻烷烃芳构化的因素，包括金属类型、结晶度、酸度、空速、沸石预处理、轻烃共投料和操作因素，如温度等，以确定沸石与金属的体系如何有助于实现高转化率的芳构化。

Effective factors on performance of zeolite based metal catalysts in light hydrocarbon aromatization

Abstract Aromatic hydrocarbons are essential compounds, that the presence of which in fuels can improve the octane number. The conversion of the light alkanes to high value aromatics is vital from theoretical and industrial standpoints. Zeolites such as ZSM-5 play an essential role in the aromatization of light alkanes. This paper highlights the mechanism of aromatization of light alkanes such as methane, ethane, propane, butane, and its isomers. Furthermore, effective factors on the aromatization of light alkanes including metal type, crystallinity, acidity, space velocity, pretreatment of zeolites, co-feeding of light hydrocarbon, and operating factors such as temperature have been investigated to determine how a system of zeolite with metals can be useful to reach aromatization with high conversion.
