Abstract:
1. A method for optimizing the operation of a reaction section synthesizing hydrocarbons from a feed comprising synthesis gas, which is operated in the presence of a catalyst comprising cobalt, said method comprising synthesizing said hydrocarbons, in a three-phase reactor in which catalyst is suspended in an essentially inert liquid phase and in a reactive gas phase comprising the feed: a) determining the theoretical partial pressure of CO in the reaction section; b) adjusting the partial pressure of CO determined in step a) to a value of 4 bar or higher by at least one of 1, 2 or 3: 1) increasing the total pressure in said reaction section; 2) increasing the concentration of CO in the feed by employing one and/or the other of 2.1) or 2.2): 3) reducing the degree of CO conversion; c) determining a new value for the theoretical partial pressure of CO in the reaction section to ensure that the theoretical partial pressure reaches a value of 4 bar or higher.
