processo de preparação de catalisadores úteis na liquefação direta de carvão e o catalisador assim obtido

摘要

A method to obtain a catalyst of transition metals supported on a carbonaceous material, via impregnation, with a solution of metal-thiourea complex, obtained from precursor salts. The formation of the sulfur on the surface of the support occurs through the thermal decomposition of the complex. The obtained catalysts are applicable toward the direct liquefaction of coal.
