Abstract:
A process for the production of hydrocarbons from synthesis gas which comprises:a) continuously feeding to the bottom of a reactor for Fischer-Tropsch reactions, containing the catalyst dispersed in the liquid phase, a synthesis gas essentially consisting of hydrogen and carbon monoxide in molar ratios H.sub.2 /CO ranging from 1 to 3;b) continuously discharging from the head of the reactor, the Fischer-Tropsch reaction product essentially consisting of a hydrocarbon liquid phase containing the catalyst, in suspension;c) feeding the suspension to at least a first hydrocyclone to obtain a concentrated bottom product, recycled to the synthesis reactor, and a partially separated product containing from 0.5 to 15% by volume of solid particles;d) feeding the partially separated product to at least a second hydrocyclone to obtain a second concentrated bottom product, recycled at least partially to the first hydrocyclone, and a stream of liquid substantially without solid particles.
