    • In one embodiment,the invention relates to a formed copper chromite catalyst prepared from a blend comprising from about 20 to about 80% by weight of copper chromite and from about 20 to about 80% by weight of at least one extrudable inorganic binder material wherein the catalyst has a surface area of from about 20 to about 225 m.sup.2 /g, and the total pore volume of the pores in said catalyst having a diameter of up to about 95,000 .ANG. is between about 0.35 to about 1 cc/g. In another embodiment, the invention relates to a process for preparing the formed copper chromite catalyst of the invention, and the process comprises(A) preparing a blend comprising from about 20 to about 80% by weight of copper chromite, from about 20 to about 80% by weight of at least one extrudable inorganic binder material, from about 1 to about 10% by weight, based on the weight of the binder, of a peptizing agent, and sufficient water to form an extrudable blend;(B) extruding the blend to form an extrudate; and(C) calcining the extrudate.The invention also relates to a process for hydrogenating aldehydes, ketones, carboxylic acids and carboxylic acid esters with catalysts of the type described.
    • 在一个实施方案中,本发明涉及由共混物制备的形成的亚铬酸铜催化剂,其包含约20至约80重量%的亚铬酸铜和约20至约80重量%的至少一种可挤出无机粘合剂材料,其中 催化剂具有约20至约225m 2 / g的表面积,并且所述催化剂中具有高达约95,000安瓿的直径的孔的总孔体积为约0.35至约1cc / g。 在另一个实施方案中,本发明涉及一种制备本发明的形成的亚铬酸铜催化剂的方法,该方法包括(A)制备共混物,其包含约20至约80重量%的亚铬酸铜,约20至约 80重量%的至少一种可挤出无机粘合剂材料,约1至约10重量%,基于粘合剂的重量,胶溶剂和足够的水以形成可挤出的共混物; (B)挤出共混物以形成挤出物; 和(C)煅烧挤出物。 本发明还涉及用所述类型的催化剂氢化醛,酮,羧酸和羧酸酯的方法。
