3815 11 00 to 3815 19 90 · Supported catalysts
These are catalysts of a widely used type which are deposited on a support, generally by impregnation, coprecipitation or mixing. They usually consist either of one or more active substances deposited on a support or of mixtures with a basis of active substances. The active substances are usually very finely divided metals, metallic oxides or other metallic compounds. The metals most commonly used are those belonging to group VIII of the periodic table (especially cobalt, nickel, palladium and platinum) and molybdenum, chromium, copper and zinc. The support generally consists of alumina, silica gel, fossil meal, whether or not activated, ceramic materials, etc.
They are used in industrial processes for the production of organic and inorganic compounds and in petroleum refining (for example, in ammonia synthesis, hydrogenation of fats, hydrogenation of olefins).
This category of catalysts also includes the following products:
1. certain preparations, based on compounds of transition metals, the function of which is to facilitate oxidation, and consequently elimination in the form of carbon dioxide in the course of combustion, of carbon residues (as in boilers and burners);
2. ‘post-combustion’ catalysts intended to be introduced into the exhaust systems of motor vehicles in order to reduce the polluting effect of the exhaust gases by converting the carbon monoxide into carbon dioxide and by converting other toxic products (for example, heterocyclic compounds) resulting from the combustion of petrol.
