Abstract:
1. A fixed-bed reactor for carrying out reactions of fluid reaction mixtures in the presence of a heterogeneous particulate catalyst having a structured packing which forms interstices in the reactor interior, in which the reactor has first and second part regions which are arranged in alternation and which differ by the specific surface area of the structured packing in such a manner that in the first part regions the quotient of the hydraulic diameter for the gas stream through the structured packing and the equivalent diameter of the catalyst particles is in the range from 2 to 20, the catalyst particles being introduced into the interstices, distributed and discharged loose under the action of gravity and in the second part regions the quotient of the hydraulic diameter for the gas stream through the structured packing and the equivalent diameter of the catalyst particles is less than 1 and no catalyst particles are introduced into the second part regions.
