PROCESS FOR THE PRODUCTION OF HYDROCARBONS FROM SYNTHESIS GAS WHICH COMPRISES: a) FEEDING TO THE BOTTOM OF A REACTOR FOR FISCHER-TROPSCH REACTIONS A SYNTHESIS GAS WITH MOLAR RATIOS H2/CO RANGING FROM 1 TO 3; b) DISCHARGING FROM THE HEAD OF THE REACTOR A HYDROCARBON LIQUID PHASE CONTAINING THE CATALYST, IN SUSPENSION; c) FEEDING THE SUSPENSION TO AT LEAST A FIRST HYDROCYCLONE TO OBTAIN A PARTIALLY SEPARATED PRODUCT CONTAINING FROM 0.5 TO 15BY VOLUME OF SOLID PARTICLES; d) FEEDING THE PARTIALLY SEPARATED PRODUCT TO AT LEAST A SECOND HYDROCYCLONE TO OBTAIN A STREAM OF LIQUID SUBSTANTIALLY WITHOUT SOLID PARTICLES. e) MOST ULLUSTRATIVE DRAWING
