Abstract:
A process for the production of hydrocarbons from synthesis gas which comprises:a) feeding continuously to the bottom of a reactor for Fischer-Tropsch reactions, containing a catalyst comprising supported cobalt, 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 reactor the Fischer-Tropsch reaction product essentially consisting of a hydrocarbon liquid phase containing the catalyst, in suspension;c) feeding the Fischer-Tropsch reaction product, together with a hydrogen stream, to a hydrocracking reactor operating at a temperature ranging from 200 to 500.degree. C.;d) discharging a vapour phase essentially consisting of light hydrocarbons from the head of the hydrocracking reactor and from the bottom a suspension containing heavier products, which is recycled to the Fischer-Tropsch reactor;e) cooling and condensing the vapour phase leaving the hydrocracking reactor,wherein the catalyst is catalytically active for both the Fischer-Tropsch reactions and hydrocracking reactions.
