Abstract

A catalytic reactor for industrial-scale hydrogenation processes is described. The catalytic reactor contains a catalytic fixed bed that comprises a support structure and a catalyst. During operation of the reaction in the catalytic reactor, the fixed bed is filled with reaction medium to at least 85% by volume. A very high contact area of the catalyst with the reaction medium is at the same time provided. The support structure is formed from material webs having a thickness of 5 to 25 μm, with a crosslinking density of at least 3 mm−3 present. The support structure consists of metals selected from elements of groups 8, 6 and 11 of the periodic table of the elements and mixtures thereof.
