  • Catalyst for hydrohalogenation of hydrocarbons
    Patent number: 5183797
    Abstract: A process for hydrohalogenating methanol with a hydrogen halide using a catalyst having an initial zone of lower activity and subsequent zones of higher activity so that coke formation and pressure drop are decreased and catalyst life is increased while overall high catalyst activity is maintained. One example of such a process uses a low surface area amorphous alumina in an initial zone and then progressively higher surface area alumina in subsequent zones.
    Type: Grant
    Filed: November 7, 1991
    Date of Patent: February 2, 1993
    Assignee: The Dow Chemical Company
    Inventors: Michael T. Holbrook, Lawrence A. Hebert, Stephen W. Najmy, Ernest F. Stine, Jr., Reimer Hasche
