CARRIER MATRIX FOR COLLECTING CATALYTICALLY ACTIVE COMPOUNDS AND PRODUCTION PROCESS

摘要

A carrier matrix intended to catalytically active compounds, for example catalysts used for the catalytic cracking of nitric oxydes is comprised of a metal support (1), an intermediate enamel layer (3) adhering to said support and a coating layer (5) of porous ceramic applied to the intermediate enamel layer. The production of said support matrix is carried out by tempering the metal support in an enamel suspension and by firing between 800 and 900 C. The metal enamelled support is then tempered in a ceramic suspension and is subjected to a new firing in order to obtain the coating ceramic layer which forms the support layer for the catalytic action compounds.
