  • Patent number: 8329765
    Abstract: Process for converting synthesis gas to hydrocarbons in a slurry reactor in the presence of a Fischer-Tropsch catalyst comprising cobalt and zinc oxide. The process is carried out by a) activating the Fischer-Tropsch catalyst with a reducing gas consisting of hydrogen and an inert gas at a temperature between 330 and 400° C., and b) contacting the activated Fischer-Tropsch catalyst from step a) with synthesis gas in the slurry reactor in order to convert the synthesis gas into hydrocarbons.
    Type: Grant

  • Publication number: 20090298958
    Abstract: The present invention relates to a process for converting synthesis gas to hydrocarbons, in particular to hydrocarbons in the C5-C60 range particularly suitable for use as liquid motor fuels, in a slurry reactor in the presence of a Fischer-Tropsch catalyst comprising cobalt and zinc oxide wherein the Fischer-Tropsch catalyst is activated with a reducing gas consisting of hydrogen and an inert gas at 330 to 400° C. prior to contact with synthesis gas in the slurry reactor.

  • Patent number: 7071238
    Abstract: Process for the conversion of synthesis gas to hydrocarbons, at least a portion of which are liquid at ambient temperature and pressure, by contacting the synthesis gas at an elevated temperature and pressure with a suspension comprising a particulate Fischer-Tropsch catalyst suspended in a liquid medium, in a reactor system comprising at least one high shear mixing zone and a reactor vessel. The process comprises passing the suspension and synthesis gas through the high shear mixing zone(s) where the synthesis gas is broken down into gas bubbles and/or irregularly shaped gas voids; discharging suspension having gas bubbles and/or irregularly shaped gas voids dispersed therein from the high shear mixing zone(s) into the reactor vessel; and introducing a liquid coolant into the reactor system.
