Abstract
The catalytic reactor has a catalyst member in the form of a stage of different orientations from one another and with flow-guiding elements which form crossing subflow ducts and which have a catalyst thereon. The flow-guiding elements are at an angle of inclination W of at least 10.degree. to the main flow direction and form partly open flow-crossing places between the subflows. The height H of a stage corresponds to a displacement factor H/HO of at least 1/2 where HO=Dctg W and D equals the diameter (or width) of the catalyst member. Satisfactory homogenization of the catalytic reaction and satisfactory heat removal via the heat-conductive rector wall are therefor achieved. The selectivity of the chemical reaction is improved and slip substantially obviated.
Claims21
A reactor for heterogeneous reactions comprising
- a heat conductive wall defining a chamber;
- at least one inlet for introducing a flowable medium into said chamber;
- at least one outlet for removing flowable medium from said chamber;
- conveyor means for conveying a medium through said inlet into said chamber;
- and
- a catalyst member in said chamber for effecting a heterogeneous reaction therein, said catalyst member having at least two consecutively disposed stages, each said stage having a plurality of flow guiding elements disposed in parallel to a main flow direction of the flowable medium through said chamber with said elements of one of said stages being angularly disposed relative to said elements of the other of said stages relative to said main flow direction, each said stage having a preset height (H), add a preset diameter (D) with each said flow guiding element defining subflow ducts disposed in crossing relation to the subflow ducts of an adjacent guiding element at an angle of inclination (W) of at least 10.degree. relative to said main flow direction and with partly open flow-crossing places between facing subflow ducts, each stage having a displacement factor H/HO of at least 1/2 wherein HO is equal to D ctg W.
