    • The invention relates to a process for preparing a Pt/zeolite catalyst material, the material itself, and the use of the material in removing carbon monoxide from a gas. In a preferred embodiment, the invention relates to a process for preparing a Pt/zeolite catalyst material for the catalytic removal of CO in H.sub.2 -rich gas by means of selective CO oxidation and the use of such a catalyst material. The catalyst materials of the invention can be prepared by employing Pt(NH.sub.3).sub.4 Cl.sub.2.H.sub.2 O and a zeolite material. The resulting material can be used for the catalytic removal of CO from an H.sub.2 -rich outlet gas mixture from a methanol reforming reactor. The compositions and methods to produce catalytic materials result in products with high and prolonged catalyst activity. In particular, the methods and compositions of the invention can be used in removing CO from the hydrogen fed to fuel cells in electric vehicles having stored methanol fuel.
    • 本发明涉及一种制备Pt /沸石催化剂材料的方法,该材料本身以及该材料用于从气体中除去一氧化碳的用途。 在优选的实施方案中,本发明涉及一种用于通过选择性CO氧化和使用这种催化剂材料来催化除去富H2气体中的CO的Pt /沸石催化剂材料的方法。 本发明的催化剂材料可以通过使用Pt(NH 3)4 Cl 2·H 2 O和沸石材料来制备。 所得到的材料可用于从来自甲醇重整反应器的富H 2出口气体混合物中催化除去CO。 生产催化剂材料的组成和方法产生具有高和延长催化剂活性的产品。 特别地,本发明的方法和组合物可用于从储存有甲醇燃料的电动车辆中向供给燃料电池的氢气中除去CO。
