Process of preparing Catalysts useful in the direct liquefaction of Coal and The Catalyst thus obtained

摘要

? The present Invention relates to a method for obtaining Catalysts of Transition Metals supported on a Carbonaceous material impregnated with a solution of the complex Path of metaltiourea, obtained from the precursor Salts. The formation of sulfide on the surface of the substrate is carried out by the thermal decomposition of the complex.A process for obtaining a catalyst useful for the direct liquefaction of Coal, characterized in that it comprises the following steps: a) preparation of the Coordination compounds metaltiourea from adding an aqueous solution of a Salt of one or several metal precursor Transition to a solution of Tiou00farea,At room temperature, which can be selected from the range between 290 and 310 K, in which the addition of Salt Precursor to thiourea is performed at a flow rate of 0.5 to 1 ml / l min; (b) Impregnation of thermally stabilized Carbonaceous material used as Catalyst Support under Vacuum and in the presence of ultrasonic agitation; and (c) Activation of The Catalyst by thermal treatment and at Atmospheric Pressure.The process for obtaining a catalyst useful for the direct liquefaction of Coal of claim 1 wherein In Step (a) preparation of the Coordination compounds metaltiourea, metal: The molar ratio of thiourea is within the range of 1: 2 and 1: 5.
