    Abstract: Procedimiento para el hidrogenado de un compuesto orgánico que presenta al menos un grupo carbonilo, en el que se pone en contacto el compuesto orgánico, en presencia de hidrógeno, con un cuerpo moldeado que es obtenible según un procedimiento en el que (i) se pone a disposición un material oxídico desecado y calcinado, que presenta material soporte y componente activo, que comprende óxido de cobre, óxido de cinc y óxido de aluminio, (ii) se añade al material oxídico polvo metálico pulverulento o cemento pulverulento, o una mezcla de los mismos, empleándose polvo de cobre y polvo de cemento con una distribución de tamaños de grano en la que al menos un 45 % de partículas de cobre o cemento poseen tamaños de grano en el intervalo de 10 a 100 m, y (iii) se moldea la mezcla resultante de (ii) para dar un cuerpo moldeado.

    Abstract: A process for producing catalysts that contain pacified copper and zinc oxide and/or aluminum oxide, comprises: (i) Precipitating a mixture of catalyst precursors which are dissolved in a solvent or in a sludge, using precipitating agents that contain anions. (ii) The mixture is washed and dried to form a solid catalyst precursor in powder or granulate form. (iii) The precursors are calcined until the anion content is 0.1-2.5wt%. (iv) The calcined precursors are then shaped and reduced and pacified, to form the catalyst. (v) Precipitation tales place by the addition of carbonates, and in the precipitation of zinc and aluminum salts the Zn:Al ration is 3:1-1:3, and the alkali carbonate solution has a pH of 5-12 and a temperature of 20-100 degrees C. (vi) The precipitate is separated and washed to remove the alkali ions. (vii) After drying, calcining takes place at 250-800 degrees C.

    Abstract: Copper-containing catalysts for low-temperature conversion at temperatures of from 150 to 300 DEG C and at from 10 to 40 bar which additionally contain aluminium, and zinc, if desired in the form of the compounds or oxides, and are prepared by joint precipitation, the copper-containing catalysts containing potassium and having a BET surface area matched to the potassium content, the potassium content being set to from 0.1 to 3.0% by weight at a BET surface area of from 30 to 160 m /g, and their use for the production of hydrogen and carbon dioxide from carbon monoxide and water.
