A method for charging a catalyst into a reactor () comprising a separation loop (), comprising the following steps:

Loading a catalyst into a bubble column for Fischer-Topsch synthesis

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.

Reactor for exothermic or endothermic catalytic reactions

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:

Process for synthesizing hydrocarbons from synthesis gas with control of the temperature of the external loop

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.

Injection of additive into a unit for synthesising hydrocarbons starting from synthesis gas enabling a homogenous concentration of catalyst to be controlled and maintained

The device described in the present invention can separate fine solid particles in suspension in a viscous liquid, withdrawing a clear liquid from the top of the device, and a dense liquid charged with solid particles is withdrawn from the bottom. The invention also concerns the application of this device to the separation of catalyst particles in a liquid phase Fischer-Tropsch synthesis process.
