摘要
The invention relates to a method for synthesizing linear paraffinic hydrocarbons from a feed including carbon monoxide and dihydrogen in the presence of a catalyst including a mesoporous oxide matrix and a mass percentage of cobalt of between 0.5 and 60%, expressed in wt.% of metal relative to the total weight of said catalyst, said catalyst being prepared according to a preparation method including at least the steps of: a) mixing in an aqueous or hydro-organic solvent at least one molecular precursor including cobalt and at least one colloidal precursor of said mesoporous oxide matrix including at least one element X selected from the group consisting of silicon, aluminum, titanium, zirconium, cerium and mixtures thereof, said molecular precursor including cobalt being made soluble in said aqueous or hydro-organic solvent; b) atomizing the mixture obtained in step a) to result in the formation of spherical droplets; c) drying said spherical droplets to obtain solid particles at a temperature of between 10 and 300°C; d) activating said solid particles via reductive treatment so as to form cobalt nanoparticles having a valence state of 0.
