Abstract: A reactor for testing catalyst systems which has a plurality of catalyst tubes ( 2 ) which are arranged parallel to one another in the interior space of the reactor and whose ends are welded into tube plates and also has caps ( 3 ) at each end of the reactor which each bound a cap space ( 4 ), with a fluid reaction medium ( 5 ) being fed via one cap space ( 4 ) into the catalyst tubes ( 2 ), flowing through the catalyst tubes ( 2 ) and being discharged via the other cap space ( 4 ), and is also provided with a heat exchange medium circuit in which the heat exchange medium ( 6 ) is fed in at one end of the reactor, flows through the intermediate space between the catalyst tubes ( 2 ) and flows out at the other end of the reactor, wherein the catalyst tubes ( 2 ) are arranged in two or more catalyst tube regions ( 7 ) which are thermally separate from one another, is proposed.

Abstract: The invention relates to a pump ( 1 ) having a pump guide tube ( 13 ) for the transport of a heat-exchange medium ( 6 ) for a reactor having a bundle of catalyst tubes ( 2 ), where the pump ( 1 ) has a casing ( 14 ) which surrounds the pump guide tube ( 13 ), having an aperture ( 15 ) in the lower part of the casing ( 14 ) via which the heat-exchange medium ( 6 ) discharged from the lower region of the reactor by means of the pump ( 1 ) flows into the casing ( 14 ), flows upward in the region between the inner wall of the casing ( 14 ) and the outer wall of the pump guide tube ( 13 ), if desired via a heat exchanger ( 18 ), flows into the interior of the pump guide tube ( 13 ) via an aperture ( 16 ) in the upper region of the pump guide tube ( 13 ), flows through the pump guide tube ( 13 ) from top to bottom and flows via an aperture ( 17 ) in the lower region of the pump guide tube ( 13 ) into the reactor, into the upper region of the interspace between the catalyst tubes ( 2 ).
