  • Patent number: 7533700
    Abstract: A hydrocarbon fuel composition which is suitable for sue in a fuel cell apparatus and an internal combustion engine comprises at least one saturated aliphatic hydrocarbon having 4 to 12 carbon atoms, and is characterised by an olefin content of less than 20% by volume, an aromatics content of less than 42% by volume, a final boiling point (fop) of less than 215° C., and a sulphur content of less than 20 ppm.
    Type: Grant
    Filed: July 13, 2006
    Date of Patent: May 19, 2009
    Assignee: BP Oil International Limited
    Inventors: Graham Butler, Stephen David Cook, Michael Graham Hodges, Graham Walter Ketley, Gregory James Lang
  • Patent number: 6822007
    Abstract: Apparatus suitable for the conversion of synthesis gas to liquid hydrocarbon products, comprising a plurality of injector-mixing nozzles, a tank reactor, a gas recycle line having a first end and a second end and a slurry recycle line having a first end and a second end. The plurality of injector-mixing nozzles is arranged at or near the top of the tank reactor, each injector mixing nozzle having a first inlet for a suspension of a catalyst in a liquid medium, at least one second inlet for synthesis gas and an outlet positioned within the tank reactor for discharging a mixture of synthesis gas and the suspension from the injector-mixing nozzles in a downwards direction into the tank reactor. The tank reactor has a first outlet for discharging a product suspension at or near the bottom thereof and a second outlet for a gaseous recycle stream at or near the top thereof.

  • Publication number: 20040132839
    Abstract: A process for the conversion of synthesis gas into higher hydrocarbon products in a system comprising a high shear mixing zone and a post mixing zone wherein the process comprises: a) passing a suspension of catalyst in a liquid medium through the high shear mixing zone where the suspension is mixed with synthesis gas; b) discharging a mixture of synthesis gas and suspension from the high shear mixing zone into the post mixing zone; c) converting at least a portion of the synthesis gas to higher hydrocarbons in the post mixing zone to form a product suspensi n comprising catalyst suspended in the liquid medium and the higher hydrocarbons; d) separating a gaseous stream comprising uncoverted synthesis gas from the product suspension; e) recycling the separated gaseous stream to the high shear mixing zone; and f) recycling at least a portion of the product suspension to the high shear mixing zone.

  • Publication number: 20030212150
    Abstract: A process for the conversion of synthesis gas into higher hydrocarbon products in a system comprising a high shear mixing zone and a post mixing zone wherein the process comprises: a) passing a suspension of catalyst in a liquid medium through the high shear mixing zone where the suspension is mixed with synthesis gas; b) discharging a mixture of synthesis gas and suspension from the high shear mixing zone into the post mixing zone; c) converting at least a portion of the synthesis gas to higher hydrocarbons in the post mixing zone to form a product suspension comprising catalyst suspended in the liquid medium and the higher hydrocarbons; d) separating a gaseous stream comprising uncoverted synthesis gas from the product suspension; e) recycling the separated gaseous stream to the high shear mixing zone; and f) recycling at least a portion of the product suspension to the high shear mixing zone.
