  • Process for the preparation of hydrocarbons
    Patent number: 4640766
    Abstract: C.sub.4.sup.- hydrocarbons are converted into syngas with a H.sub.2 /CO molar ratio between 0.25 and 2.25 by reforming at a pressure above 10 bar in the presence of specified amounts of carbon dioxide and steam followed by conversion of the syngas into C.sub.5.sup.+ hydrocarbons over a cobalt-containing catalyst or a catalyst combination comprising a cobalt-containing catalyst and having CO-shift activity.
    Type: Grant
    Filed: April 19, 1985
    Date of Patent: February 3, 1987
    Assignee: Shell Oil Company
    Inventors: Martin F. M. Post, Swan T. Sie, Ernst J. R. Sudholter
  • Process for the preparation of hydrocarbons from a mixture of CO and H.sub. 2
    Patent number: 4628133
    Abstract: A two-step process is disclosed wherein C.sub.9.sup.+ hydrocarbons are prepared from C.sub.4.sup.- hydrocarbons by steam reforming followed by Fischer-Tropsch synthesis over a special cobalt-containing catalyst. Yields of C.sub.9.sup.+ hydrocarbons are increased by recycling a gaseous fraction comprising unconverted H.sub.2 and CO as well as C.sub.8.sup.- hydrocarbon by-products and steam to the steam reformer.
    Type: Grant
    Filed: September 23, 1985
    Date of Patent: December 9, 1986
    Assignee: Shell Oil Company
    Inventors: Johannes K. Minderhoud, Martin F. M. Post, Swan T. Sie, Ernst J. R. Sudholter
  • Process comprising reforming, synthesis, and hydrocracking
    Patent number: 4587008
    Abstract: A two-step process is disclosed wherein C.sub.9.sup.+ hydrocarbons are prepared from C.sub.4.sup.- hydrocarbons by steam reforming followed by Fischer-Tropsch synthesis over a special cobalt-containing catalyst. Yields of C.sub.9.sup.+ hydrocarbons are increased by recycling a gaseous fraction comprising unconverted H.sub.2 and CO as well as C.sub.8.sup.- hydrocarbon by-products and steam to the steam reformer.
    Type: Grant
    Filed: October 30, 1984
    Date of Patent: May 6, 1986
    Assignee: Shell Oil Company
    Inventors: Johannes K. Minderhoud, Martin F. M. Post, Swan T. Sie, Ernst J. R. Sudholter
  • Process for the preparation of hydrocarbons
    Patent number: 4579985
    Abstract: C.sub.5.sup.+ hydrocarbons are prepared from C.sub.4.sup.- hydrocarbons by a two-stage process comprising steam reforming followed by Fischer-Tropsch synthesis over a special cobalt-containing catalyst; a gaseous fraction comprising unconverted H.sub.2 and CO as well as C.sub.4.sup.- hydrocarbons and CO.sub.2 formed as by-products is separated from the synthesized product and recycled to the steam reformer.
