Patent ID: 8476182

Claim:
A process to obtaining a catalyst suitable for direct coal liquefaction characterized in that the following steps are carried out: a) Preparation of the metal-thiourea coordination compounds by adding an aqueous solution of a precursor salt of one or more transition metals selected from molybdenum, iron, nickel, or cobalt to a thiourea solution, at room temperature that can be selected from the interval between 290 and 307 K, and where the addition of the precursor salt to the thiourea is carried out at a flow of 0.5 to 1 mL/min; b) Impregnation of a carbonaceous material, thermally stabilized at temperatures between 973 and 1473 K, used as support of the catalyst under vacuum and sonicated; and c) Catalyst activation by thermal treatment at selected temperatures between 420 and 460 K and atmospheric pressure.
