The catalyst according to the invention is obtained by bringing into contact: a. At least one complex of formula MLn in which M is a metal chosen from iron, ruthenium, nickel, rhodium and molybdenum, n is the number of ligands around the metal M and L is an ionic or covalent ligand; b. At least one activator of formula M'Rm in which M' is a metal chosen from aluminium, lithium, sodium, magnesium and zinc, m is the valency of the metal M' and R is chosen from a hydrogen atom and hydrocarbon radicals, the molar ratio b/a being between 0.3 and 20; and c. At least one compound chosen from conjugated dienes, phosphines, amines, arsines and phosphites, the molar ratio c/a being between 1 and 20. Its preparation is performed by bringing the components a, b and c into contact in at least one essentially anhydrous aromatic solvent and at least partially under an inert gas atmosphere. The catalyst can be applied to the manufacture of hydrocarbons and of aliphatic oxygen compounds by a reaction between carbon monoxide and hydrogen in a molar ratio CO/H2 or between 0.2 and 2, at a pressure of between 5 and 400 bars, at a temperature of between 160 DEG C and 300 DEG C, the residence time of the reaction mixture being between 0.1 and 150 seconds. |
