    • A reduced or partially reduced nickel-molybdenum catalyst prepared by a process having the steps of 1) reacting nickel carbonate and molybdenum oxide precursors to form nickel molybdate and 2) treating the nickel molybdate under reducing conditions to form the reduced or partially reduced nickel-molybdenum catalyst. There is also a process for making the catalyst. There is also a process for using the catalyst in the hydrogenation of an oxo aldehyde, thereby forming an oxo alcohol of high selectivity. There is also a process for forming an oxo alcohol from the hydroformylation/hydrogenation of an olefinic feedstream. There is also a process for forming an oxo alcohol by contacting formates, dimers, trimers, and organic acids with hydrogen in the presence of a reduced or partially reduced nickel-molybdenum catalyst. The foregoing processes are also useful with a catalyst having the general formula YxZ wherein Y is nickel and/or cobalt and Z is molybdenum and/or tungsten; and wherein x ranges between about 0.25 to about 4.0. There are also reduced or partially reduced catalysts of the general formula NixMo or YxZ wherein x ranges between about 0.25 to about 4.0 and wherein oxide precursors of the catalysts are substantially free of ammonium groups.
    • 通过具有以下步骤的方法制备的还原或部分还原的镍 - 钼催化剂:具有以下步骤:1)使碳酸镍和氧化钼前体反应形成钼酸镍,和2)在还原条件下处理钼酸镍以形成还原或部分还原的镍 - 钼 催化剂。 还有一种制备催化剂的方法。 还有一种使用催化剂加氢羰基醛的方法,从而形成高选择性的羰基合成醇。 还有从烯烃进料流的加氢甲酰化/氢化形成羰基合成醇的方法。 还有一种通过在还原或部分还原的镍 - 钼催化剂存在下使甲酸盐,二聚体,三聚体和有机酸与氢接触来形成羰基合成醇的方法。 上述方法对于具有通式Y x Z Z的催化剂也是有用的,其中Y是镍和/或钴,Z是钼和/或钨; 并且其中x在约0.25至约4.0之间。 还有还原或部分还原的通式为Ni x Mo或Y x Z z的催化剂,其中x在约0.25至约4.0之间,其中催化剂的氧化物前体是 基本上不含铵基团。
