Beschreibung:In the field of heterogeneous catalysis, it is convenient to distinguish, in a perfectly unjustified and oversimplified way, between metal catalysts, and the other catalysts. The first are easy to define : they are those in which a reduced metal is the active phase. It is thus easy to circumscribe, by exclusion, the other class namely the "non-metals". We have adopted this definition for the sake of our colleagues working on catalysis by metals, and to avoid a lengthy title like "sm' face properties and catalysts by transition metal oxides, sulfides, carbides, nitriles, etc. Defined in this manner, non-metal catalysts represented, in 1980, 84 wt. % of the industrial heterogeneous catalysts. To be more specific, this proportion corresponds to catalysts which, under the working conditions in the industrial plant contain their catalytically active metallic elements in a non-reduced state. It should however be recalled that most metal catalysts are supported on oxides, which, often, represent over 90% (sometimes 99.4% in the case of the platinum reforming catalysts) of the total weight
