PROCESS FOR THE SYNTHESIS OF HYDROCARBONS FROM SYNTHESIS GAS IN THE PRESENCE OF A CATALYST BASED ON COBALT TRAPPED IN A MESOPOROUS OXIDE MATRIX AND OBTAINED FROM AT LEAST ONE MONOMERIC PRECURSOR

摘要

A process for the synthesis of linear paraffinic hydrocarbons from a feed of carbon monoxide and dihydrogen in the presence of a catalyst of a mesoporous oxide matrix and a content by weight of the element cobalt of 0.5% to 60%, wherein the catalyst is prepared bya) mixing, in an aqueous or hydro-organic solvent, a molecular precursor containing cobalt and a molecular precursor of the mesoporous oxide matrix containing element X of silicon, aluminium, titanium, zirconium and or cerium;b) aerosol spray drying the mixture to form spherical liquid droplets;c) drying to obtain solid particles at a temperature of 10° C. to 300° C.;d) activation by a reduction treatment to form nanoparticles of cobalt with an oxidation state of 0.
