Abstract
In a reactor ( ) which has a bundle of catalyst tubes ( ) and in which a heat transfer medium is circulated through the space surrounding the catalyst tubes, with the ring lines ( ) at both ends of the reactor with openings ( ) through the wall for introduction or removal of a heat transfer medium by means of one or more pumps, where the heat transfer medium is introduced into the lower ring line ( ) and is returned via the upper ring line ( ) to the pump(s) and the heat transfer medium or a substream of the heat transfer medium may, if desired, be passed over one or more external heat exchangers, and with deflecting plates ( ) which alternately leave free an open cross section in the middle of the reactor and at the edge of the reactor, the lower ring line ( ) is divided by means of a horizontal dividing wall ( ) into two regions between which material can pass via preferably uniformly distributed openings ( ) having a regulatable open cross section.
