摘要
A process for the production of liquid hydrocarbons by the Fischer-Tropsch process comprises a step a) for generating a synthesis gas, a step b) for Fischer-Tropsch synthesis, a step c) for condensing the gaseous effluent obtained during step b), a step d) for separating the effluent condensed during step c) to obtain a gaseous effluent enriched in carbon monoxide and hydrogen, and a step e) for recycling at least a portion of the enriched gaseous effluent obtained during step d) to the Fischer-Tropsch synthesis step b), characterized in that:1) two molar ratio of concentrations, A1 and A2, are determined between the hydrogen and the carbon monoxide (H2/Co), A1 being the value of said ratio in the supply to the synthesis step b), and A2 being the value of said ratio in any one of the gaseous effluents obtained during steps b) to e);2) comparing ratios A1 and A2; and3) adjusting the concentrations of hydrogen and/or carbon monoxide in the synthesis gas to keep the difference between the two ratios A1 and A2 substantially constant.展开▼
