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

A process for producing jet fuel comprising the following steps:

Process for producing jet fuel from a hydrocarbon synthesis product stream

The present invention concerns an integrated process for the production of liquid hydrocarbons starting from a feed containing at least one fraction of biomass and optionally at least one fraction of another feed, said process comprising at least one pre-treatment step, a gasification step, a step for conditioning synthesis gas, a water scrubbing step, a step for eliminating acid gases, a final purification step, and a catalytic Fischer-Tropsch synthesis reaction step.

Process for the conversion of a feed containing biomass for the production of hydrocarbons, by Fischer-Tropsch synthesis

A process in which the paraffinic effluent derived from a Fischer-Tropsch synthesis unit is separated to obtain a heavy C+ fraction, said heavy fraction then being hydrogenated in the presence of a hydrogenation catalyst at a temperature in the rangeC to&#xb0; C, at a total pressure in the rangetoMPa, at an hourly space velocity in the rangeto, and at a hydrogen flow rate corresponding to a hydrogen/hydrocarbons volume ratio in the rangetoNI/I/h, the liquid hydrogenated effluent then being brought into contact with a hydroisomerization/hydrocracking catalyst, with no prior separation step, the hydroisomerized/hydrocracked effluent then being distilled to obtain middle distillates and possibly oil bases.
