Abstract:
1. A process for converting a synthesis gas into liquid hydrocarbons in at least two reactors arranged in series and ending with a last reactor, said reactors containing at least one solid catalyst in suspension in a liquid phase, and wherein said reactors are essentially perfectly mixed, said process comprising feeding the last reactor at least in part with at least a portion of at least one of the gaseous fractions collected at an outlet of at least one other reactor, feeding at least one reactor with a flow of catalyst suspension obtained directly from another reactor, separating at least in part, at least one flow of catalyst suspension obtained from a reactor so as to obtain a liquid product essentially free of catalyst and a catalyst suspension enhriched in catalyst, and recycling the enriched catalyst suspension to at least one said reactor, wherein the gas Péclet number is less than 0.18, and the diameter of the reactors is greater than 6 meters.
