Process for the preparation of hydrocarbons from synthesis gas

摘要

Process for the production of hydrocarbons from synthesis gas which comprises: a) feeding to a reactor for Fischer-Tropsch reactions, containing a catalyst based on supported cobalt, a synthesis gas in molar ratios H2/CO ranging from 1 to 3; b) discharging from the reactor a hydrocarbon liquid phase containing the catalyst, in suspension; c) feeding the suspension to a hydrocracking reactor operating at a temperature ranging from 200 to 500 DEG C; d) discharging a vapour phase 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. <IMAGE>
