Abstract
A method for the partial oxidation of hydrocarbons is provided wherein an endothermic catalyst and an oxidation catalyst are positioned upon a short channel-length metallic substrate; the endothermic catalyst positioned under a surface layer of the oxidation catalyst positioned on the metallic substrate. A fuel-rich supply of hydrocarbons and oxygen is then passed over the substrate. The method includes providing an oxidation catalyst on at least a portion of a surface of the metallic substrate wherein a hydrocarbon is oxidized by an oxygen mass-transfer-limited reaction on the oxidation catalyst surface; and providing an endothermic catalyst on the metallic substrate below the oxidation catalyst surface whereby an endothermic reaction follows the oxygen mass-transfer-limited reaction below the oxidation catalyst surface.
