Abstract
A gel composition substantially contained within the pores of a solid material is disclosed for use as a catalyst or as a catalyst support in dehydrogenation and dehydrocyclization processes.
Claims13
A method of dehydrogenation a hydrocarbon comprising contacting in a dehydrogenation process reactor a hydrocarbon feed and a gel composition comprising a gel that is substantially localized within the pores of a solid material selected from the group consisting of alumina, silica, titania, zirconia, carbon, molecular sieves, porous minerals, montmorillonite clay, aluminosilicate clays, carbides, nitrides, phosphates, and sulfides;
- wherein the hydrocarbon is a C2 to C10 hydrocarbon.
A method of dehydrogenating a hydrocarbon comprising contacting in a dehydrogenation process reactor a hydrocarbon feed and a composition of matter comprising (a) a solid material having pores, and (b) a gel;
- wherein the gel is substantially localized within the pores of the solid material;
- wherein the gel comprises at least one catalytically active element, and optionally comprises chromium when the catalytically active element is other than chromium;
- and
- wherein the hydrocarbon is a C2 to C10 hydrocarbon.
The method of claim wherein said catalytically active element is chromium and said solid material having pores is alumina.
