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

A process for the hydrotreatment of a feed obtained from renewable sources in which the total stream of feed F is divided into a number of different part-streams of feed F1 to Fn equal to the number of catalytic zones n, where n is 1 to 10. The mass flow rate of hydrogen sent to the first catalytic zone represents more than 80% by weight of the total mass flow rate of hydrogen used. The effluent from the reactor outlet undergoes at least one separation step. A portion of the liquid fraction is recycled to the catalytic zones in a manner such that the local recycle ratio for each of the beds is 2 or less, and the local dilution ratio over each of the beds is less than 4.

Process for the hydrotreatment of renewable materials, with an optimized gas recycle

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.
