Abstract:
The invention relates to a method for start-up and operation of a Fischer-Tropsch reactor comprising the steps of: providing a reactor with a fixed bed of Fischer-Tropsch catalyst precursor that comprises cobalt as catalytically active metal; supplying an initial hydrogen containing gaseous feed stream to the reactor, at a reduction temperature and pressure; supplying a further gaseous feed stream comprising carbon monoxide and hydrogen to the reactor; converting carbon monoxide and hydrogen supplied with the second gaseous feed stream to the reactor into hydrocarbons at a reaction temperature, wherein the reaction temperature is set at a value of at least 200° C. and hydrocarbons are produced.

Claim (Index 13):
A method according to  claim 1 , wherein at the start of step b) the hydrogen containing gaseous feed stream comprises substantially no nitrogen containing compound and preferably the nitrogen containing compound is added to the hydrogen containing gaseous feed stream after the start of step b) preferably the nitrogen containing compound is added to the hydrogen containing gaseous feed stream such that the nitrogen content increases over time till preferably 20 vol % based on the total feed stream.
