【摘要】 随着人们对汽油质量的要求越来越高,烷烃异构化越来越受到重视,尤其是长链烷烃异构化,因此研究高性能的异构化催化剂具有非常重要的意义。本文综述了一类用于长链烷烃异构化的新型催化剂-钨基催化剂的研究进展,介绍了此类催化剂的制备、异构化反应,简要介绍了其反应机理。并分析了此类催化剂今后的发展趋向和应用前景。更多还原

【Abstract】 As one of the main routes to produce high-octane gasoline blending components in the crude oil refining industry,alkanes isomerization has drawn much attention throughout the world because it can greatly improve the gasoline quality.For alkanes isomerization,one of the key issues is to develop catalysts with higher activity and higher stability,which has been widely pursued due to its importance both in academic research and in industrial utilization.The latest progress and the potential trend of the tungsten-based catalysts were summarized.Preparation of tungsten-based catalysts and the reactive mechanism were reviewed in this paper.Finally,the developing prospect of tungsten-based catalysts was predicted.更多还原
