Abstract: A process for applying a highly crystalline form of silica, for example Silicalite, to a supporting structure, with a small thermal mass, such as a screen or a metal surface is described. A slurry of finely-divided high silica zeolite and a silicone or polytetrafluoroethylene binder is coated onto the support structure. Optionally, a noble catalyst is applied to the high silica zeolite either before or after the high silica zeolite is coated onto the support structure. The support structures coated according to this process can be used to catalyze flameless combustion of hydrogen or hydrocarbon gases with suitable amounts of air or oxygen if a noble metal catalyst is applied, or as an adsorbent structure in the absence of the metal catalyst.
