Abstract:
1. A process for the production of liquid hydrocarbons by the Fischer-Tropsch process comprising a) for generating a synthesis gas essentially comprising carbon monoxide and hydrogen, b) Fischer-Tropsch synthesis from a supply comprising at least a portion of the synthesis gas, to produce an effluent comprising synthesized liquid hydrocarbons and at least one gaseous effluent, c) condensing the gaseous effluent obtained during b), d) separating the effluent condensed during c) to obtain a gaseous effluent enriched in carbon monoxide and hydrogen, an aqueous phase and liquid hydrocarbons, and e) recycling at least a portion of the enriched gaseous effluent obtained during d) to the Fischer-Tropsch synthesis b), wherein: 1) two molar ratio of concentrations, A 2) comparing ratios A 3) adjusting the concentrations of hydrogen and/or carbon monoxide in the synthesis gas to keep the difference between the two ratios A
