| 摘要 |
The invention is a composition that is suitable for reducing sulfur species from products produced by petroleum refining processes, especially gasoline products produced by fluidized catalytic cracking (FCC) processes. The composition comprises zeolite, yttrium, and at least one element selected from the group consisting of magnesium and manganese. The yttrium and the element are present (i) as cations exchanged onto the zeolite, and optionally (ii) in pores of the catalyst matrix. The zeolite is preferably a zeolite Y. |
