TECHNOLOGY FOCUS - METALLURGY - Preferred Catalyst Member: The catalyst member further comprises activity loss for the generation of hydrogen of less than or equal to 3 (preferably less than or equal to 2, especially less than or equal to 1) % for greater than or equal to 1000 minutes with an input stream comprising gasoline vapor at 250degreesC at a space velocity of 44500 hour-1, a stoichiometric oxygen/carbon ratio of 1.05:1, and at catalyst operating temperatures of 950 - 1050degreesC. The generation of the hydrogen is in an amount of greater than or equal to 21 mol.% for greater than or equal to 2400 minutes. The catalyst member comprises base metal (10 - 500 g/ft3) per cubic foot of the catalyst member. The catalyst member comprises rhodium (20 - 50 g/ft3) per cubic foot of the catalyst member.Preferred Method: In (M1), the base metal catalytic component comprises nickel, where rhodium was not added to the base metal catalytic component, and where nickel was not added to the rhodium catalytic material. Depositing the base metal catalytic component on the substrate further involves coating the substrate with a slurry comprising a nickel compound and support material to form a nickel coated substrate; drying the nickel coated substrate; and calcining the nickel coated substrate to form a layer of nickel catalytic material before depositing the rhodium catalytic material on it. Depositing the layer of rhodium catalytic material further involves coating the substrate with a slurry comprising a rhodium compound and a second support material to form a rhodium coated substrate; drying the rhodium coated substrate; and calcining the rhodium coated substrate to form the layer of rhodium catalytic material.

The base metal catalytic component comprises nickel and where rhodium was not added to the base metal catalytic layer during their formation. EXAMPLE - A dual-layered rhodium (Rh)/nickel (Ni) catalyst member was prepared by depositing nickel catalytic slurry (1.86 g) on cylindrical foamed zirconia-toughened alumina (ZTA) substrate having 20 pores per inch and a length and diameter each of 1 inch (2.54 cm). The coated substrate was then dried and calcined for 1 hour at 538degreesC. A nickel layer comprising nickel catalytic material (0.92 g) was thus deposited on the substrate. Then, rhodium catalytic slurry (2.2 g) was deposited on the substrate, which was again dried and calcined for 1 hour at 538degreesC, resulting in a rhodium layer of rhodium catalytic material (1.02 g) over the nickel layer, with the rhodium thus segregated from the nickel. The resulting Rh/Ni catalyst member (A1) comprised of rhodium (35 g/ft3) and nickel (32 g/ft3). (A1) was subjected to testing using gasoline vapor having a composition complying with California Air Resources Board (CARB) Phase II requirements, at 250degreesC, and a space velocity of 44500 hours, with a stoichiometric oxygen/carbon ratio of 1.05:1, and at catalyst operating temperatures of 950 - 1050degreesC. The effluent was tested to determine the content of hydrogen, carbon monoxide, methane, ethane, and ethylene. (A1) Produced hydrogen (22 mol.%) throughout the first 1200 minutes of the test with no substantial loss in activity, and produced hydrogen (more than 21 mol.%) even after about 2400 minutes.
