Patent ID: 7560047

Claim:
A method of preparing a synthetic gas containing hydrogen and carbon monoxide by autothermal reforming reaction of gasoline with a structured catalyst, said method comprising the steps of: providing a reaction temperature the range of from 600 to 1000° C.; providing a space velocity in the range of from 1,000 to 50,000 hr −1 ; providing a molar ratio of a reactant water and gasoline in the range of H 2 O:C=0.1 to 5; providing a molar ratio of a reactant oxygen and gasoline in the range of O/C=0.1 to 3; and reacting the reactants in the presence of said structured catalyst which is prepared by a method comprising the steps of: 1) preparing an aqueous alumina solution having a pH value of 2 to 5; 2) adding 2 to 7 wt % of polyvinyl alcohol, 3 to 7 wt % of methyl cellulose, and 1 to 5 wt % of phosphoric acid to the aqueous alumina solution to form a mixture, wherein the weight percentages of the polyvinyl alcohol, the methyl cellulose, and the phosphoric acid are based on the weight of the solid content in the aqueous alumina solution, stirring and ball-milling said mixture to prepare an alumina slurry; 3) coating the alumina slurry on a ceramic honeycomb support to form an alumina coated support; 4) separately, ball-milling a gasoline reforming transition metal catalyst to form a powder; 5) preparing a reforming transition metal catalyst slurry from said powder; and 6) washcoating said alumina coated support with the reforming transition metal catalyst slurry to form said structured catalyst.
