The invention relates to a method for start-up of a Fischer-Tropsch reactor comprising the following steps:
(a) providing a reactor with a fixed bed of Fischer-Tropsch catalyst that comprises cobalt as catalytically active metal, the fixed bed comprising an upstream part and a downstream part, wherein the catalyst in the upstream part of the fixed bed is in a non-reduced state and the catalyst in the downstream part of the fixed bed is in a reduced state;
(b) supplying a gaseous feed stream comprising carbon monoxide and hydrogen to the reactor and converting carbon monoxide and hydrogen supplied with the gaseous feed stream to the reactor into hydrocarbons at a reaction temperature and at a set reactor productivity, wherein the reaction temperature is initially at least 200 °C, and maintaining the set reactor productivity by adjusting the reaction temperature. |
