    Abstract: Preparation of chlorine involves passing hydrogen chloride and gas stream comprising molecular oxygen in a reactor (1) having parallel catalyst tubes (2) charged with fixed-bed catalyst and at least one deflector plate (6) perpendicular to the reactor. The plates leave passages on opposite sides of the reactor free next to its interior wall. A liquid heat transfer medium circulates between tubes.

    Abstract: Method for preparing (meth)acrolein and/or (meth)acrylic acid by partial gas-phase oxidation of 3-4C precursors in presence of a heterogeneous, particulate catalyst (A). Method for preparing (meth)acrolein and/or (meth)acrylic acid by partial gas-phase oxidation of 3-4C precursors in presence of a heterogeneous, particulate catalyst (A). Oxidation is done in a reactor having 2 or more vertical thermal plates (1), arranged in parallel and with gaps (2) between them, where (2) contain the catalyst and the gaseous reaction mixture is supplied to (2). The new feature is that the method is monitored, controlled and/or regulated through one or more temperature measurements, taken in one or more (2), at one or more measuring sites, distributed over the height of each (2). An independent claim is also included for a method of incorporating temperature-measuring devices into a reactor, on the same side of the reactor as the feed line for supplying gaseous reaction mixture.

    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.
