Abstract
In a process for the catalytic hydrogenation of a carbonyl compound or a mixture of two or more carbonyl compounds in the presence of catalyst tablets which comprise an inorganic, TiO2-containing support and, as active component, copper or a mixture of copper with at least one metal selected from the group consisting of zinc, aluminum, cerium, nobel metals and metals of transition group VIII and whose copper surface area is not more than 10 m2/g, the diameter d and/or the height h of the tablets is less than 3 mm.
Claims5
A process for the catalytic hydrogenation of an aliphatic hydroxyaldehyde or a mixture of two or more of these aldehydes in the presence of catalyst tablets which comprise an inorganic, TiO2-containing support and, as active component, copper or a mixture of copper with at least one metal selected from the group consisting of zinc, aluminum, cerium, nobel metals and metals of transition group VIII and whose copper surface area is not more than 10 m2/g, metallic copper powder being added to the catalyst material prior to tabletting, wherein the diameter d and/or the height h of the tablets is in each case 1.5 mm.
A catalyst tablet which comprises an inorganic, TiO2-containing support and, as active component, copper or a mixture of copper with at least one metal selected from the group consisting of zinc, aluminum, cerium, nobel metals and metals of transition group VIII and whose copper surface area is not more than 10 m2/g, metallic copper powder being added to the catalyst material prior to tabletting, wherein the diameter d and/or the height h of the tablet is in each case 1.5 mm.
