    摘要： The present invention generally relates to a Fischer-Tropsch process, in particular a Fischer-Tropsch process for converting a feed comprising a mixture of hydrogen and carbon monoxide gases, preferably in the form of a synthesis gas mixture, to hydrocarbons by contacting a cobalt-containing Fischer-Tropsch synthesis catalyst with a mixture of hydrogen and carbon monoxide in a reactor at a pressure of 4.0 MPa absolute or greater, wherein the process is initiated by a start-up procedure comprising the steps of: i) providing a feed comprising a mixture of hydrogen and carbon monoxide gases, preferably in the form of a synthesis gas mixture, to a reactor containing a cobalt-containing Fischer-Tropsch synthesis catalyst, wherein the pressure inside the reactor is 3.5 MPa absolute or below; and ii) maintaining the feed to the reactor, removing a product stream comprising hydrocarbons and maintaining the pressure inside the reactor at 3.5 MPa absolute or below for at least 15 hours, preferably for at least 50 hours.
