  • Shell catalyst, in particular for oxidation of methanol to formaldehyde, and also method for production thereof
    Patent number: 7803972
    Abstract: The invention relates to a coated catalyst, especially for oxidation of methanol to formaldehyde, which, on an inert, preferably essentially nonporous, support body, has at least one coating which comprises, before the removal of the organic fractions of components b) and c): (a) oxides, or precursor compounds convertible to the corresponding oxides, of molybdenum and iron, where the molar ratio of Mo:Fe is between 1:1 and 5:1, and optionally further metallic components or metal oxide components or precursor compounds convertible to the corresponding oxides, (b) at least one organic binder, preferably an aqueous dispersion of copolymers, especially selected from vinyl acetate/vinyl laurate, vinyl acetate/ethylene, vinyl acetate/acrylate, vinyl acetate/maleate, styrene/acrylate or mixtures thereof, and (c) at least one further component selected from the group consisting of SiO2 sol or precursors thereof, Al2O3 sol or precursors thereof, ZrO2 sol or precursors thereof, TiO2 sol or precursors thereof, waterglas
