  • Patent number: 10576444
    Abstract: A method for charging a catalyst into a reactor (40) comprising a separation loop (21), comprising the following steps: a) filling the reactor (40) with a solvent S1; b) filling the separation loop (21) with said solvent S1; c) causing said solvent S1 to move in the synthesis reactor (40) and the separation loop (21); d) heating the reactor (40) to a temperature of 100° C. or less; e) injecting an inert gas into the bottom of the reactor (40); f) mixing said catalyst with a solvent S2 in a vessel (30) in order to obtain a liquid/solid mixture; g) increasing the pressure in the vessel (30) then sending the liquid/solid mixture to the reactor (40); h) withdrawing said solvent S1 and/or S2.

  • Patent number: 9387456
    Abstract: Reactor for Fischer-Tropsch reaction which is carried out in a three-phase system essentially consisting of a reacting gaseous phase, a reacted liquid phase and a solid catalytic phase, wherein the solid catalytic phase consists of packed or structured bodies of catalytic material encaged within at least one honeycomb monolithic structure with a high thermal conductivity.

  • Patent number: 9290699
    Abstract: The present invention concerns a process for the synthesis of hydrocarbons from a feed comprising synthesis gas, in which a solid catalyst comprising cobalt is used in a three-phase reaction section operated such that said catalyst is maintained in suspension in a liquid phase by movement of a gas phase from the bottom to the top of said reaction section, said process comprising an external loop for separating waxes, characterized in that: 1) the theoretical ratio PH2O:PH2 in the external loop for separating waxes is determined using the following calculation: PH2O:PH2 theoretical=Cv/(R1?Rft×Cv) where Cv=(COinlet?COdegas)/COinlet R1=H2 inlet/COinlet Rft=(H2 inlet?H2 degas)/(COinlet?COdegas) 2) if the theoretical ratio PH2O:PH2 determined in step 1) has a value of Rthreshold or higher, the temperature in the degassing means for the external loop for separating waxes is reduced, 3) steps 1) to 2) are repeated until the theoretical ratio PH2O:PH2 has a value strictly less than Rthreshold, where Rthreshold

  • Patent number: 9090832
    Abstract: The invention relates to a process for synthesising hydrocarbons starting from a feedstock containing synthesis gas. In the process a solid Fischer-Tropsch catalyst is employed in a three-phase reaction section operated so that the catalyst is maintained in suspension in a liquid phase by the circulation of a gaseous phase from the bottom to the top of the reaction section. The process utilizes conditions to control and maintain the homogeneity of the concentration of catalyst particles in the reaction section.
