AMMONIA SYNTHESIS CATALYST AND ITS PRODUCTION METHOD |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide an ammonia synthesis catalyst having a high activity without any influence on purity of a gas of a raw material even at a low temperature and a low pressure and a method for producing an ammonia synthesis catalyst in which the ammonia synthesis catalyst can inexpensively be produced in a simple way. <P>SOLUTION: The ammonia synthesis catalyst by which ammonia is synthesized from a gas containing hydrogen and nitrogen comprises ruthenium supported on a carrier containing ceria and magnesium. The method for producing an ammonia synthesis catalyst comprises a step for producing an oxide precursor in which the oxide precursor is produced using a cerium compound containing solution and a magnesium compound containing solution, a step for supporting ruthenium in which the ruthenium is supported on the oxide precursor using a solution containing a ruthenium containing compound, and a step of heat treatment in which the oxide precursor is oxidized to form the oxide and substantially at the same time the ruthenium supported is metallized. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
