A supporting matrix for catalytically active compounds, for use, for example, in catalysts for the catalytic cracking of nitrogen oxides, is constructed of a metal core (1), an intermediate layer (3) of vitreous enamel bonded onto this core, and a porous ceramic cover coating (5) applied to the vitreous enamel intermediate layer. The supporting matrix is made by dipping the metal core into a vitreous enamel slip followed by firing at 800.degree. to 900.degree. C. The enameled metal core is then fired in a second firing to form the ceramic cover coating which represents the actual support for the catalytically active compounds.

Storage material for heat transfer

Apparatus and method for cleaning the heat exchanging surfaces of the heat transfer plates of rotary regenerative heat exchangers comprising low to medium pressure gas and/or steam operated nozzles of the injection type having injection tubes for moving by suction ambient heat exchanging gas or air into the interspaces between the heat transfer plates. The nozzles may be designed as supersonic nozzles, especially Laval nozzles.
