Claims
- 1. A reforming catalyst comprising a solid porous alumina support containing platinum and iridium or platinum, iridium and copper, said catalyst being prepared by the process of applying to said support a dimethylsulfoxide solution containing soluble compounds of the metals, selected from the group consisting of metal salt, metal acid, metal ammine and metal ammine halide, drying the resulting solids and calcining.
- 2. The catalyst of claim 1 wherein the solid porous support is eta-alumina.
- 3. The catalyst of claim 1 wherein the solid porous support is alpha monohydrate alumina.
- 4. The catalyst of claim 1 wherein the porous support is a mixture of alumina and an aluminosilicate.
- 5. The catalyst of claim 1 wherein the metals are platinum and iridium.
- 6. The catalyst of claim 1 wherein the metals are platinum, iridium and copper.
- 7. The catalyst of claim 1 wherein said compounds of the metals are joined with the solid porous support by dissolving said compounds of the metals in dimethylsulfoxide, mixing the dimethylsulfoxide solution with the solid porous support, heating the resulting slurry, recovering the solids therefrom, drying the solids and calcining.
- 8. The catalyst of claim 7 wherein the recovered solids are washed first in dimethylsulfoxide and then in water prior to said drying and calcining.
- 9. A process for the preparation of the catalyst of claim 1 comprising mixing the solid porous support with a solution of the said soluble metal compounds in dimethylsulfoxide, subjecting the resulting slurry to refluxing, separating the solids from the slurry, drying the solids and calcining.
- 10. The process of claim 9 wherein the soluble metal salts are chloroplatinic acid and iridium chloride.
- 11. The process of claim 9 wherein the soluble metal salts are chloroplatinic, acid, iridium chloride and copper chloride.
