Abstract

The catalytic compositions comprise a catalytically active material which is homogeneously interspersed throughout a monolithic structure of ceramic composition. The composition is shaped into a unitary monolith which is employed as the catalyst structure. In the method the active material or materials are admixed with a ceramic material, which can be either active or inactive, in finely divided form and then shaped into the monolithic structure. The catalytic compositions are used with reactants in a combustion process.
