    摘要: A method of treating off-gas from a Fischer-Tropsch reaction comprises recovering the off-gas and hydrogenating a portion of the olefins present in the off-gas and converting a portion of the carbon monoxide present in the off-gas to carbon dioxide or methane. The treated off-gas is then fed to a hydrogen manufacturing unit such as a steam reformer to form hydrogen that can be used elsewhere in the process.

    摘要: A process for the synthesis of hydrocarbons in a three phase reactor comprising the steps of: (i) introducing synthesis gas into the reactor; (ii) causing the synthesis gas to be contacted with a Fischer-Tropsch catalyst; and (iii) removing products from the reactor, wherein step (i) comprises introducing some or all of the synthesis gas into the reactor at or near the bottom of the reactor; and step (ii) comprises contacting the synthesis gas with a catalyst structure immobilised within the reactor, wherein the catalyst structure comprises one or more porous catalyst elements fixable within the reactor, each of said porous catalyst elements being at least 1 cm3, preferably at least 10 cm3, in size and wherein the open volume within each porous catalyst element is at least 60% (with reference to the volume of the porous catalyst elements) and each porous catalyst element includes a Fischer-Tropsch catalyst material.

    摘要: A method of treating off-gas from a Fischer-Tropsch reaction is disclosed, the method comprising the steps of: (i) recovering the off-gas from a Fischer-Tropsch reaction, and (ii) hydrogenating a portion of the olefins present in said off-gas. In preferred embodiments the hydrogenated off-gas is used as a feed for a hydrogen manufacturing unit based on steam reforming. Carbon monoxide can be oxidised or methanated. A CuO/ZnO based catalyst can be used to hydrogenate the olefins. The present invention allows Fischer-Tropsch off-gas (containing unconverted syngas, olefins, C1-C4 hydrocarbons and inerts) to be recycled which is more efficient than using it as fuel.
