Patent ID: 7547659

Claim:
A method of preparing a structured catalyst for reforming gasoline for fuel-cell powered vehicles, comprising the steps of: 1) preparing an aqueous alumina solution having a pH of from 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 with reference to the weight of the solid content in the aqueous alumina solution; 3) stirring and ball-milling said mixture to prepare an alumina slurry; 4) coating the alumina slurry on a ceramic honeycomb support to form a support having an alumina coating; 5) ball-milling of gasoline reforming transition metal catalyst powder to prepare a catalyst slurry; and 6) washcoating said support having an alumina coating with the catalyst slurry to form the structured catalyst.
