Abstract:
A catalytic converter comprising a monolith, a structure for immobilizing the monolith, and a casing, wherein the structure for immobilizing the monolith is a microporous molding wherein said microporous molding comprises60-95% by weight of finely divided metal oxide, 0.5-10% by weight of inorganic fibers which do not represent a health risk, 0-35% by weight of opacifiers, 0-10% by weight of organic fibers, and 0-30% by weight of refractory material which expands at a temperature above 300Â° C., said microporous molding which, prior to installation in said catalytic converter has a density of 100-240 kg/m3, without taking into account the refractory material, and has a compression to at least 96% of its original thickness when subjected to a pressure of 1 bar for a period of 5 minutes, and wherein after said compression recovers to more than 70% of its initial value by one minute after removal of compressing pressure.
