Abstract
Method for fabricating a filter or catalytic reactor for hot exhaust gases, which includes a filter bed made from a frangible material such as steel wool or the like. The latter is confined and formed into a quasi-rigid body by application of an initial outer hardenable surface of a rigidizing material. Thereafter the preformed bed in an unconfined state, is treated to provide it with a uniform coating to a desired thickness in anticipation of being fitted into an appropriately shaped casing.

Method for fabricating a reactor unit having a thermally stable, reactant coated, gas permeable reactor element which includes the steps of:
- initially confining a mass of a fibrous metallic reactor media within a constricting and shaping means,
- depositing a hardenable layer of a base material to surfaces of the confined reactor media in sufficient amount to form a cohesive, quasi-rigid mass which will retain a configuration equivalent to the shaping means subsequent to said layer, of base material becoming dried, and said quasi-rigid media mass being released from the confining means,
- removing the confining and shaping means from about the coated fibrous mass, and applying an external layer of reactant material on to said base layer to a desired thickness thereby producing a reactor element,
- installing said reactor element within a reactor casing.
