Abstract: Mezcla catalítica que se obtiene de un catalizador metálico en polvo con un material solido (que aquí se denomina ôcoadyuvante de reaccionö) que tiene buenas propiedades de filtrado, no interfiere con la reaccion, no interfiere con el reciclaje del catalizador de retorno hacia la reaccion, no interfiere con la refinacion ni con la recuperacion del metal desde el catalizador una vez que este está agotado, y no se separará del catalizador durante la preparacion de dicha mezcla catalítica, la reaccion química ni la separacion de dicha mezcla catalítica del medio de reaccion, mientras que la proporcion del coadyuvante de reaccion al catalizador varía dentro del rango entre 0,05 y 20 sobre una base en peso. La mezcla catalítica se puede utilizar para la transformacion catalítica de compuestos.

Abstract: Se hidrogenan nitrocompuestos con un catalizador de Ni activado que se dopa durante la activacion y/o después de la misma con uno o más elementos de la lista: Mg, Ca, Ba, Ti, Zr, Ce, Nb, Cr, Mo, W, Mn, Re, Fe, Co, Ir, Ni, Cu, Ag, Au, Rh, Ru y Bi mientras que antes de la activacion la aleacion de Ni/Al puede no contener, pero preferentemente puede contener uno o más elementos dopantes de la lista de Ti, Ce, V, Cr, Mo, W, Mn, Re, Fe, Ru, Co, Rh, Ir, Pd, Pt y Bi. Si antes de la activacion la aleacion de Ni/Al contiene uno o más de los elementos dopantes apropiados para la aleacion mencionados anteriormente, el catalizador que se obtiene como resultado se puede dopar luego con uno o más de los elementos de la lista Mg, Ca, Ba, Ti, Zr, Ce, V, Nb, Cr, Mo, W, Mn, Re, Fe, Ru, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au y Bi por adsorcion sobre la superficie del catalizador.

Abstract: A shaped Raney metal fixed bed catalyst is obtained by homogenizing a mixture of powders consisting of catalyst alloy, a binder, a moistening agent and optionally an additive, shaping to form a molded catalyst precursor which is calcined below 850 deg C to form sintered catalyst precursor and activating. The final catalyst is washed and doped with rhenium. A mixture of powders consisting of catalyst alloy, a binder, a moistening agent and optionally an additive selected from shaping aid, lubricant, plasticizer, pore producer, is homogenized. The catalyst alloy consist of at least one Raney metal as catalytically active metal, a leachable alloy component and optionally a promoter. The homogenized product is shaped to form a molded catalyst precursor which is calcined below 850 deg C to form sintered catalyst precursor and activated by leaching the leachable alloy component with alkali. An activated outer layer of thickness 0.05-1 mm, is formed. The final catalyst is washed and doped with rhenium by introducing into a perrhenic acid solution of sufficient pH for preset time to fix all rhenium on the catalyst. An Independent claim is also included for the production of fixed bed catalyst.
