Abstract
A process for producing a catalyst element including fixing a ceramic sheet to a jig or mold having a predetermined configuration, and thereafter, impregnating the ceramic sheet with a catalyst solution, drying and calcining to allow a catalyst element to retain the predetermined configuration or the catalyst element to be fixed in the mold. The catalyst element may be produced by fixing the ceramic sheet to a metallic thin plate, followed by processing into a predetermined configuration.

A process for producing a catalyst element comprising:
- (a) fixing a ceramic sheet including an organic binder to a jig having a configuration, and
- (b) thereafter, impregnating said ceramic sheet with a slurry consisting essentially of a catalyst support, a liquid, and a catalyst solution consisting essentially of a catalyst and a solvent, and
- (c) drying and calcining the impregnated sheet resulting from step (b) to produce a catalyst element retaining the configuration.
A process for producing a catalyst element comprising:
- (a) fixing a ceramic sheet including an organic binder to a mold having a configuration, and
- (b) thereafter, impregnating said ceramic sheet with a slurry consisting essentially of a catalyst support, a liquid, and a catalyst solution consisting essentially of a catalyst and a solvent, and
- (c) drying and heat-treating the impregnated sheet resulting from step (b) to produce a catalyst element retaining the configuration as well as to fix said catalyst in said mold.
