Abstract
A process for producing a compact catalytic reactor, in which reaction spaces or heat-transfer spaces are formed by stacking at least partially structured plates alternately one on top of the other, a catalyst is introduced into the reaction spaces, and the plates are provided with a layer of solder at least in the edge region, but not in the region provided with catalyst material, and, after stacking them one on top of the other, are soldered to form a reactor. In addition, the plates may be provided with a bent-up edge region a for easy positioning and for increasing the leak tightness. Finally, an unstructured intermediate plate may also be respectively provided between the structured plates.
Claims10
A process for producing a compact catalytic reactor, said process comprising:
- forming respective reaction spaces and heat-transfer spaces, by stacking at least partially structured plates alternately one on top of the other;
- introducing catalyst material into the reaction spaces;
- providing a layer of solder at least in an edge region of the plates, but not in regions provided with catalyst material;
- and
- applying heat and pressure to the plates such that said layer of solder bonds the plates to form a catalytic reactor.
