摘要: An improved process for the catalytic partial oxidation of hydrocarbons to produce hydrogen and carbon monoxide and less than ˜2% carbon dioxide is disclosed. The process further permits the reaction to be initiated at room temperature, and utilizes a metal catalyst deposited on a ceria-coated zirconia monolith support, which exhibits high conversions of hydrocarbons to synthesis gas (hydrogen and carbon monoxide).

摘要: Novel means for sealing reactors used in reaction processes are disclosed. A catalyst impregnated carrier material is provided in the gap between the monolith catalyst and the refractory lining of the reactor. The catalytic carriers are the same catalyst materials or have substantially similar catalytic activity as the catalytic monolith. Additionally, the catalytic material is applied as a thin catalytic film deposited on the refractory lining. These methods provide not only pressure drop to minimize reactant flow along the inner wall of refractory lining, but also additional active reaction zone. This sealing method is suitable for any types of reactions on catalytic monoliths, particularly syngas production by partial oxidation of methane to reduce methane and oxygen leakages.
