Process for producing liquid hydrocarbons from a heavy feedstock such as biomass, carbon, lignite, or heavy petroleum residue comprising: A partial oxidation b) of the heavy feedstock, producing a synthesis gas SG1, with an H2/CO ratio <1; A vapor reforming c) of a light feedstock that comprises hydrocarbons having at most 4 carbon atoms, for the production of a synthesis gas SG2 with an H2/CO ratio >3; A Fischer-Tropsch conversion into liquid hydrocarbons of a synthesis gas SG, mixture of at least a portion of SG1 and at least a portion of SG2, in proportions such that SG has an H2/CO ratio of between 1.2 and 2.5. The light feedstock comprises hydrocarbons that have less than 10 carbon atoms C1-C10 that are obtained from a pretreatment of the heavy feedstock and/or are produced in the Fischer-Tropsch stage and/or during a downstream hydrocracking.
