Abstract
The invention relates to use of a catalyst comprising particles of nickel dispersed in a porous silica matrix for catalyzing a methanation reaction. There is also described a method for methanation of a feedstock at least comprising gases carbon monoxide and hydrogen, said method comprising contacting the feedstock with the catalyst.
Claims17
A method for methanation of a feedstock comprising carbon monoxide and hydrogen, said method comprising contacting the feedstock with a catalyst comprising particles of nickel dispersed in a porous silica matrix, said catalyst comprising about 20 wt % to about 63 wt % metallic nickel, and said catalyst having pores which extend continuously from an outside surface of the silica matrix to an outside surface of the nickel, wherein the active nickel surface area in said catalyst is about 50 m2/g to 160 m2/g Ni.
A method for reducing the carbon monoxide content of a gas mixture comprising carbon monoxide and hydrogen, said method comprising exposing the gas mixture to a catalyst comprising particles of nickel dispersed in a porous silica matrix, said catalyst comprising about 20 wt % to about 63 wt % metallic nickel, and said catalyst having pores which extend continuously from an outside surface of the silica matrix to an outside surface of the nickel, wherein the active nickel surface area in said catalyst is about 50 m2/g to 160 m2/g Ni.
A method for reducing the carbon monoxide content of a gas, said method comprising adding hydrogen to said gas to form a gas mixture and exposing the gas mixture to a catalyst comprising particles of nickel dispersed in a porous silica matrix, said catalyst comprising about 20 wt % to about 63 wt % metallic nickel, and said catalyst having pores which extend continuously from an outside surface of the silica matrix to an outside surface of the nickel, wherein the active nickel surface area in said catalyst is about 50 m2/g to 160 m2/g Ni.
