摘要： The invention concerns a method for temporarily interrupting a Fischer-Tropsch reaction implemented on a feedstock comprising at least carbon monoxide and hydrogen, in a three-phase bed reaction zone comprising a liquid phase, a gas phase and solid catalyst particles maintained in suspension, said method including the following steps: a) interrupting the reaction and b) restarting said reaction, while maintaining the solid catalyst particles in suspension in the reaction zone, a) during step of interrupting the reaction, stopping the supply of feedstock, and establishing in the reaction zone, an inhibiting gas blanket comprising less than 1 vol. %. of hydrogen and at least 5 vol. % of at least one inhibiting agent selected among the group consisting of carbon monoxide and water, and b) during the step of restarting the reaction, establishing, in the reaction zone, an activating gas blanket having a hydrogen content of at least 20 vol. % and restarting the supply of feedstock.

摘要： The inventive method for producing liquid hydrocarbons by Fischer-Tropsch involves a stage (a) for generating a syngas, a stage (b) for carrying out a Fischer-Tropsch synthesis, a stage (c) for condensing a gas flow obtained at the stage (b), a stage (d) for separating the flow condensed at the stage (c), thereby obtaining a gas flow enriched in hydrocarbons and hydrogen and a stage (e) for recycling at least a part of the enriched gas flow obtained at the stage (d) towards the Fischer-Tropsch synthesis stage (b). Said method is characterised in that it consists 1) in determining two molar ratios A1 and A2 between hydrogen and carbon monoxide (H2/CO), wherein A1 is the value of said ratio in the supply of the synthesis stage (b) and A2 is the value of said ration in any of different gas flows obtained at the stages from (b) to (e), 2) in comparing the A1 and A2 ratios and 3) in adjusting the hydrogen and/or carbon monoxide concentration in the syngas in such a way that a substentially constant deviation between two A1 and A2 ratios is maintained.

摘要： The invention relates to a catalyst which can be applied to a method for converting synthesis gas, said catalyst comprising: a) a support made of a solid solution containing at least one first aluminate element with a mixed spinel structure of formula MxM'(1-X)AI2O4/AI2O3.SiO2, x ranging from 0 to 1 being excluded, or a simple spinel structure of formula MAI2O4/AI2O3 SiO2, wherein the support is calcinated in an at least partially oxidizing atmosphere at a temperature ranging from 850 °C to 900 °C, b) an active phase which is deposited on the support which contains one or several metals of group VIII, selected from amongst cobalt, nickel, ruthenium or iron. The catalyst is used in a fixed bed or in a suspension in a triphasic reactor for the synthesis of hydrocarbons from a CO, H2mixture.

摘要： The invention relates to a method for optimising the operation of a reaction section for the synthesis of hydrocarbons from a stock containing a synthesis gas, the method being carried out in the presence of a cobalt-containing catalyst. The method includes the following steps: a) determining a theoretical molar ratio PH20:PH2 in the reaction section; b) optionally adjusting the ratio PH20:PH2 determined in step a) to a value strictly lower than 1; c) determining the new value of the theoretical molar ratio PH20:PH2 in the reaction section; and repeating steps a) to c) until the ratio PH20:PH2 between the water and hydrogen partial pressures has a value strictly lower than 1.1.
