The invention relates to methods for producing supported catalysts, comprising: providing a metal foam element A made of nickel; applying an aluminum-containing powder MP to metal foam element A, such that metal foam element AX is obtained; thermally treating metal foam element AX in order to form an alloy between metal foam element A and the aluminum-containing powder MP, such that metal foam element B is obtained; oxidatively treating metal foam element B, such that metal foam element C is obtained; and applying a catalytically active layer, comprising at least one carrier oxide and at least one catalytically active component, to at least one part of the surface of metal foam element C, such that a supported catalyst is obtained. The invention also relates to the supported catalysts obtained according to the method, and to the use thereof in chemical transformations.

Metal foam supported catalyst and method for the production thereof

The present invention relates to a method for producing supported catalysts, comprising: providing a metal foam element A, which consists of metallic cobalt, an alloy of nickel and cobalt, or an arrangement of layers of nickel and cobalt, lying one over the other; applying an aluminum-containing powder MP to metal foam element A in order to obtain metal foam element AX; thermally treating metal foam element AX to achieve alloy formation between metal foam element A and aluminum-containing powder MP, in order to obtain metal foam element B; oxidatively treating metal foam element B, in order to obtain metal foam element C; and applying a catalytically active layer, comprising at least one support oxide and at least one catalytically active component, to at least part of the surface of metal foam element C, in order to obtain a supported catalyst. The present invention further relates to the supported catalysts that can be obtained using the method and to the use of said supported catalysts in chemical transformations.

The present invention relates to a process for producing alcohols by hydrogenation of C4 to C20 aldehydes. The process according to the invention is performed in two consecutive hydrogenation stages, wherein the first hydrogenation stage employs an activated metal catalyst based on a nickel metal foam and the second stage employs a supported catalyst containing a catalytically active component from the group consisting of nickel, copper, chromium and mixtures thereof.

Process for the hydrogenation of aldehydes in at least two hydrogenation stages

The present invention relates to processes for producing metal foam bodies, in which metal-containing powders that may comprise aluminium and chromium or molybdenum are applied to metal foam bodies that may comprise nickel, cobalt, copper and iron and then treated thermally, wherein the highest temperature in the thermal treatment of the metal foam bodies is in the range from 680 to 715° C., and wherein the total duration of the thermal treatment within the temperature range from 680 to 715° C. is between 5 and 240 seconds. Following this method of thermal treatment can achieve alloy formation at the contact surface between metal foam body and metal-containing powder, but simultaneously leave unalloyed regions within the metal foam. The present invention further comprises processes comprising the treatment of the alloyed metal foam bodies with basic solution. The present invention further comprises the metal foam bodies obtainable by these processes, which find use, for example, as support and structure components and in catalyst technology.
