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.

Claim (Index 1):
A method for manufacturing hydrocarbons by operating a Fischer-Tropsch reactor comprising a fixed bed of reduced Fischer-Tropsch catalyst that comprises cobalt as catalytically active metal, said method comprising the steps of:\n a) supplying a gaseous feed stream comprising carbon monoxide and hydrogen to the reactor; b) converting carbon monoxide and hydrogen supplied with the gaseous feed stream to the reactor into hydrocarbons at an initial reaction temperature; c) obtaining an initial hydrocarbon stream from the Fischer-Tropsch reactor; d) optionally, determining the concentration of hydrocarbons having a chain length of at least 41 carbons (C41+) in the initial hydrocarbon stream obtained in step c), being the initial C41+ concentration; e) adding to the gaseous feed stream a nitrogen-containing compound other than molecular nitrogen such that the nitrogen-containing compound is present in the gaseous feed stream in a concentration of up to 10 ppmV; f) obtaining, during and/or after addition of the nitrogen-containing compound, a further hydrocarbon stream from the Fischer-Tropsch reactor having a second C41+ concentration which is less than the initial C41+ concentration; and wherein the second C41+ concentration is at least 5% less than the initial C41+ fraction.
