Patent number: 7351750Abstract: Natural gas is reacted with steam for generating carbon monoxide and hydrogen in a first catalytic reactor. The resulting gas mixture is used to perform Fischer-Tropsch synthesis in a second catalytic reactor. After performing Fischer-Tropsch synthesis, the remaining hydrogen is separated from a hydrocarbon-rich stream using a hydrogen-permeable membrane, and the hydrocarbon-rich stream is returned to be subjected to steam reforming. Preferable, the hydrogen-rich stream is supplied to a combustion channel for providing heat for the endothermic steam-reforming reaction. The overall process converts natural gas to longer-chain hydrocarbons and can provide a carbon conversion of more than 80%.Type: GrantFiled: February 25, 2004Date of Patent: April 1, 2008Assignee: CompactGTL PLCInventor: Michael Joseph Bowe

Publication number: 20080033068Abstract: A process for producing oxygenated products from a Fischer-Tropsch derived olefinic feedstock, includes reacting the feedstock, in a hydroformylation reaction stage, with carbon monoxide and hydrogen at an elevated reaction temperature and at a superatmospheric reaction pressure in the presence of a hydroformylation catalyst system. The catalyst system comprises a mixture, combination or complex of a transition metal, T, where T is selected from the transition metals of Group VIII of the Periodic Table of Elements; carbon monoxide, CO; hydrogen, H2; as a primary ligand, a monodentate phosphorus ligand; and as a secondary ligand, a bidentate phosphorus ligand which confers resistance on the catalyst system to poisoning arising from the presence of undesired components in the Fischer-Tropsch derived feedstock.Type: ApplicationFiled: November 17, 2004Publication date: February 7, 2008Applicant: SASOL TECHNOLOGY (PROPRIETARY) LIMITEDInventors: Petrus Wilhelmus Nicolaas Maria Van Leeuwen, Edyta B.
