  • Process for producing a catalyst comprising a graphite containing carbon, a transitional metal and a modifying metal ion
    Patent number: 4250057
    Abstract: Catalyst for the synthesis of ammonia from hydrogen comprises (1) as support on graphite containing carbon having (a) a basal plane surface area of at least 100 m 2/G (b) a ratio of BET surface area to basal plane surface area of not more than 5:1 and (c) a ratio of basal plane surface area to edge surface area of at least 5:1 and (ii) as active component (a) 0.1 to 50% by weight of a transition metal and (b) 0.1 to 4 times by weight of (a) of a modifying metal or ion selected from the alkali or alkaline earth metals or ions. The modifying metal or ion is actively associated with the transition metal rather than the support.
    Type: Grant
    Filed: October 6, 1978
    Date of Patent: February 10, 1981
    Assignee: The British Petroleum Company Limited
    Inventors: Alan I. Foster, Peter G. James, John J. McCarroll, Stephen R. Tennison
