    Date of Patent: September 4, 2001
    Assignee: Degussa-Huels Aktiengesellschaft
    Inventors: Daniel Ostgard, Konrad Moebus, Monika Berweiler, Barbara Bender, Gernot Stein
  • Shaped, activated metal, fixed-bed catalyst
    Patent number: 6262307
    Abstract: A shaped, activated metal, fixed-bed catalyst with a pore volume of 0.05 to 1 ml/g and an outer activated layer consisting of a sintered, finely-divided, catalyst alloy and optionally promoters. The catalyst alloy has metallurgical phase domains, resulting from the method of preparation of the alloy, in which the largest phase by volume has a specific interface density of more than 0.5 &mgr;m−1.
