Abstract
The thermal shock resistance of monolithic catalysts is improved by pre-coating a ceramic monolithic carrier, before the application of catalytic components, with an organic filling material which can be melted and burned out and which comprises a dispersion of very fine solid particles, by heating the carrier above the melting point of the filling material, then applying the catalytic components and then burning out the filling material.
