Abstract: Advance in straight-run gasoline isomerization catalysts and the use in China are introduced in this paper. At present,straight-run gasoline isomerization catalysts are focused on metal catalysts loaded on porous carrier,especially bifunctional catalysts loaded on molecular sieves. The most suitable catalyst carrier,the balance between loaded metal and carrier acid center,and the use of common metals instead of noble metals are the hot topics of research. The application of straight-run gasoline isomerization catalysts in refineries shows a diversified situation. A variety of different catalysts with their own characteristics are used by different refineries.

Key words: straight run gasoline, isomerization, catalyst

摘要: 主要介绍了直馏汽油异构改质催化剂的研究进展以及在国内的工业使用情况。目前,直馏汽油异构催化剂主要集中在多孔材料负载金属的催化剂上,尤其集中在分子筛负载金属的双功能催化剂的研发及应用上。如何选择最合适的催化剂载体,使负载金属与载体酸中心之间更匹配以促进异构反应的进行,如何对比表面积较大的多孔性材料进行改性以及以普通金属代替贵金属是当今比较热点的问题。直馏汽油异构改质催化剂的工业应用也呈现出多元化的局面,有多种不同的催化剂同时应用于不同的生产厂家,并彰显出各自的特色。
