FESTBETTREAKTOREN MIT KURZEM KATALYSATORBETT IN STROEMUNGSRICHTUNG

摘要

Reactors are described for the continuous reaction of gaseous substances on fixed-bed catalysts, involving continuous temperature control with the aid of a heat transfer medium. These reactors are characterised by the catalyst bed (3) being configured in the form of one or more regular-shape sheet-like layers having a thickness of 0.01 - 50 cm, the surface of the catalyst layers being bounded by a gas-permeable layer and said surface on the starting material inflow side (1a) and/or on the product outflow side (1b) facing, at a distance of from 0.1 to 10 cm, a wall which has a similarly regular shape and which separates the space for the substances to be reacted or the reacted substances, respectively, from the heat transfer medium space. The reactors are further characterised by the substances to be reacted being guided in such a way that they flow through the catalyst bed (3) in a direction which is approximately or entirely perpendicular to the sheet-like catalyst layers.
