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 zinc, magnesium and manganese, wherein the yttrium and element are present as cations. The yttrium and zinc are preferably present as cations that have been exchanged onto the zeolite. The zeolite is preferably a zeolite Y.
