Abstract
Multicomponent CoO-CeO2(SrO)-Pd(Pt) catalysts on ceramic monoliths of a honeycomb structure (synthetic cordierite) were shown to be efficient for the deep oxidation of methane. Based on the results of the studying the effect of Al2O3 as a second carrier-substrate, the content of CoO, modifying/promoting additives of strontium and cerium oxides, palladium, platinum on catalyst activities, it was found that a 4,9%CoO-4,9%CeO2-0,1%Pd/cordierite specimen is optimal for use in catalytic heat generators. The catalyst of this composition, with increased mechanical strength, thermal resistance and resistance to carbonization, provides CO free oxidation of methane in the stoichiometric mixture with oxygen.
