  • Process for carbon monoxide hydrogenation
    Patent number: 6765026
    Abstract: A process for the preparation of a catalyst useful for conducting carbon monoxide hydrogenation reactions, particularly Fischer-Tropsch reactions; the catalyst compositions, use of the catalyst compositions for conducting such reactions, and the products of these reactions. The steps of the process for producing the catalyst comprise impregnating a powder, or particulate refractory inorganic oxide solids, preferably silica, with a) a soluble compound or salt of a catalytic metal of the Iron Group, preferably cobalt, and b) a soluble compound, or salt, of a Group VIII noble metal, preferably platinum, suitably by sequential contact of the solids with a solution of (a) and a solution of (b), by sequential contact of the solids with a solution of (b) and a solution of (a), or by contact with a solution which contains both (a) and (b).
    Type: Grant
    Filed: February 28, 2003
    Date of Patent: July 20, 2004
    Assignee: ExxonMobil Research and Engineering Company
    Inventors: Alla Jurievna Krylova, Albert L'Vovich Lapidus, Maria Vadimovna Tsapkina
