摘要： Deoxygenation catalyst for coal mine methane, its preparation method and application in catalytic deoxygenation of coal mine methane in oxygen-containing environment. The catalyst comprises a first composition serving as the active content and a second composition serving as the additive. The first composition consists of one or more platinum group noble metals selecting from the group consisting of Pd, Pt, Ru, Rh and Ir. The second composition consists of one or more alkaline metals or alkaline earth metals selected from the group consisting of Na2O, K2O, MgO, CaO, SrO and BaO; CeO2 and lanthanides rare earth metals such as Pr, Nd, Sm, Eu, Gd, etc.; and/or transition metals such as Y, Zr, La, etc.; and/or Al2O3 oxides complexes. Said catalyst can effectively eliminate the oscillatory behavior during catalytic combustion under oxyen-lean condition. When said catalyst is applied in the catalytic deoxygenation process of the present invention, 1 to 15% of oxygen in coal mine methane can be effectively removed and a percentage yield of methane which approximately equals to the theoretical percentage yield obtained under the assumption of complete conversion of methane and oxygen can be achieved.

摘要： Provided in the present invention is a catalyst for an ATR (autothermal reforming) process of hydrogen production, as well as the methods to prepare and use it. The catalyst comprises a precious metal of the platinum family (e.g., Pt, Pd, Ru, Rh, Ir) and combinations and mixtures thereof as the active component, an alkali metal oxide and/or alkaline metal oxide as the first additive, and a CeO2-based composite oxide as the second additive. The catalyst can be used in pellet form, or may be formed into a monolithic form with all the catalytic active components and additives loaded on a support with a regular structure, such as a ceramic honeycomb, a metal honeycomb, or a metal foam.
