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.
Claims20
A catalytic reactor, comprising a catalytic fixed bed having a volume of 0.5 to 100 m3, a support structure and a catalyst, wherein, during a reaction, the catalytic fixed bed is filled with a reaction medium to at least 85% by volume and the contact area of the catalyst with the reaction medium is at least 2000 m2 per m3 volume of the catalytic fixed bed;
- and wherein:
- a) 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;
- b) 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;
- c) the support structure is catalytically inert to hydrogenation reactions under the reaction conditions prevailing in the catalytic reactor and serves as a support body for a catalyst that is applied to the support structure in the form of a catalytically active coating.
