  • Iron-based water gas shift catalyst
    Patent number: 7964114
    Abstract: The present development is a catalyst for use in water gas shift processes, a method for making the catalyst and a method of using the catalyst. The catalyst is composed of iron oxide, copper oxide, zinc oxide, alumina, and optionally, potassium oxide, and is produced using a hydrothermal synthesis process. The catalyst demonstrates surprising activity for conversion of carbon monoxide under high to moderate temperature shift reaction conditions.
    Type: Grant
    Filed: December 17, 2007
    Date of Patent: June 21, 2011
    Assignee: Sud-Chemie Inc.
    Inventors: Chao Chen, Eshan Li, Yanxia Wang, Yeping Cai, Chandra Ratnasamy, Jeffery E. Riley, Xueqin J. Wang, Shizhong Zhao, Jürgen R. Ladebeck
