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
