  • Process for the manufacture of unsaturated hydrocarbons
    Patent number: 4564642
    Abstract: A process for the production of unsaturated hydrocarbons by the catalytic hydrogenation of carbon monoxide is disclosed wherein the reaction takes place in the presence of a catalyst containing an oxide of a first metal selected from the transition metals of Group IV and a second metal selected from Group VIII of the periodic table. The reaction takes place at a reaction temperature of between about 250.degree. C. and 350.degree. C. and a reaction pressure of between about 10 and 30 bar.
    Type: Grant
    Filed: November 13, 1981

    Assignee: Ruhrchemie Aktiengesellschaft
    Inventors: Bernd Bussemeier, Carl D. Frohning, Gerhardt Horn, Werner Kluy
  • Process for the production of unsaturated hydro-carbons
    Patent number: 4455395
    Abstract: In a process for the production of unsaturated hydrocarbons comprising catalytic conversion of a feed gas comprising carbon oxides and hydrogen, the improvement which comprises carrying out said conversion at a temperature of 250.degree. to 350.degree. C. and under a pressure of 10 to 30 bars, said catalyst comprising at least one difficultly reducible oxide of the transition metals of Groups V and/or VII of the Periodic Table combined with at least one metal of Group 8 of the Periodic Table.

  • Process for preparing unsaturated hydrocarbons
    Patent number: 4423156
    Abstract: The conventional process for the preparation of unsaturated hydrocarbons comprises catalytic hydrogenation of carbon oxides at 220.degree. to 500.degree. C. and pressures of up to 30 bars. It has been found that, by carrying out the foregoing reaction in the presence of at least one low molecular weight aliphatic alcohol, the yield of olefins and the catalyst life are substantially and surprisingly improved.
