Abstract
A method is provided to promote, stabilize and strengthen metal catalysts used in the fluidized bed process for methanol synthesis which comprises the dipping of such catalysts into an alcoholic solution of metal alkoxide salt. The resulting improved catalyst is characterized by high density, low loss on attrition, and improved stability and catalytic activity.
Claims27
A composition comprising a catalytically active metal, metal oxide, metal salt or a mixture thereof which catalyzes a chemical reaction to produce methanol in the presence of gaseous carbon monoxide, hydrogen and carbon dioxide;
- a solid carrier comprising a catalytically inert metal oxide or a mixture of catalytically inert metal oxides;
- and a catalytically inert metal alkoxide coating wherein said alkoxide contains 1-10 carbon atoms.
In a method for preparing a catalytic composition comprising a catalytically active metal, metal oxide, metal salt or a mixture thereof which catalyzes a chemical reaction to produce methanol in the presence of gaseous carbon monoxide, hydrogen and carbon dioxide;
- and a solid carrier comprising a catalytically inert metal oxide or a mixture of catalytically inert metal oxides;
- the improvement comprising immersing said catalytic composition in a solution containing an inert metal alkoxide, drying said catalytic composition, immersing said catalytic composition in water, and heating said catalytic composition at a temperature from about 100.degree. F. to 600.degree. F.
A catalytic composition comprising a catalytically active material selected from the group consisting of a metal, metal oxide, a metal salt or a mixture thereof which catalyzes a chemical reaction to produce methanol in the presence of gaseous carbon monoxide, hydrogen and carbon dioxide;
- and a solid carrier comprising a catalytically inert material selected from the group consisting of a metal oxide or a mixture of catalytically inert metal oxides;
- wherein a portion of said solid carrier is provided by immersing particles comprising said catalytically active material and inert material into a solution containing a metal alkoxide, removing said particles from said solution, drying said particles, immersing said particles in water, removing said particles from said water and subjecting said particles to a temperature of about 100.degree.
