Abstract: The invention relates to a method of manufacturing hydrocarbons by operating a Fischer-Tropsch reactor comprising a fixed bed of reduced Fischer-Tropsch catalyst that comprises cobalt as catalytically active metal. Further, the present invention relates to a mixture of hydrocarbons obtainable by said Fischer-Tropsch reaction.

Abstract: The invention pertains to a method for processing a Fischer-Tropsch off-gas wherein Fischer-Tropsch off-gas is contacted with a wash fluid in a scrubber, and wherein the wash fluid is recycled in a closed loop with a dedicated scrubber, stripper and splitter. The wash fluid preferably is kerosene or LDF. The C3+ hydrocarbons that are recovered from the off-gas are, together with other Fischer-Tropsch product, subjected to hydrocracking or hydrocracking/hydroisomerization. Additionally, hydrogen is recovered from the off-gas.

Abstract: Paraffins and waxes are produced from a gaseous feed stream comprising hydrogen and carbon monoxide in a Fischer-Tropsch reactor using a fixed bed of reduced Fischer-Tropsch catalyst having cobalt as catalytically active metal. A nitrogen-containing compound is added to the gaseous feed stream in a concentration of up to 10 ppmV and the mixture if fed to the reactor to obtain paraffins having from 5 to 300 carbon atoms. The product is subjected to a hydrogenation step, to obtain a hydrogenated fraction comprising 5 to 300 carbon atoms. The hydrogenated product is separated into C5-C9, C10-C17, and C18-300 fractions. The C18-C300 fraction is separated to obtain one or more first light waxes having a congealing point in the range of 30 to 75° C. and a second heavy wax having a congealing point in the range of 75 to 120° C.
