US Classification:

502150, 502167, 502172, 502255, 502260, 208216 R, 208217

Abstract:

A method for hydrodesulfurizing FCC naphtha is described. More particularly, a Co/Mo metal hydrogenation component is loaded on a silica or modified silica support in the presence of organic ligand and sulfided to produce a catalyst which is then used for hydrodesulfurizing FCC naphtha. The silica support has a defined pore size distribution which minimizes olefin saturation.

US Classification:

208113, 502 66, 502 64, 502232, 502240, 502243

Abstract:

In a method of forming a shaped body, a mixture is formed comprising a particulate silica-rich material, water and a potassium base or basic salt, wherein the total solids content of the mixture is from about 20 to about 90 weight percent. The mixture is extruded into extrudates and the extrudates are dried and heated to a temperature of from about 300 C. to about 800 C. to form the shaped body.

Abstract:

This invention relates to the composition and synthesis of an Extra Mesoporous Y (or “EMY”) zeolite and its use in the catalytic conversion of organic compounds. In particular, this invention relates to a Y-type framework zeolite possessing a high large mesopore pore volume to small mesopore pore volume ratio. The novel zeolite obtained provides beneficial structural features for use in petroleum refining and petrochemical processes.

Abstract:

This invention relates to a catalyst and method for hydrodesulfurizing naphtha. More particularly, a Co/Mo metal hydrogenation component is loaded on a high temperature alumina support in the presence of a dispersion aid to produce a catalyst that is then used for hydrodesulrurizing naphtha. The high temperature alumina support has a defined surface area that minimizes olefin saturation.
