As catalysts for the process, metals such as Fe, Ni, Co, Cr, Mo, W, and Ru are used in the form of a colloidal suspension in an inert liquid such as a high boiling hydrocarbon oil: the suspension is obtained by decomposing the corresponding carbonyl in the liquid at raised temperature. CO is passed at 25°-120° over the metal and the gaseous carbonyl passed into the liquid and decomposed therein at the synthesis temperature of 175°-230°. It is then ready for passage of the synthesis gas therethrough.
