FIELD: chemistry.
SUBSTANCE: present invention relates to a carrier with a catalytic coating, production method thereof, use thereof in processes with heterogeneous catalysts, as well as a reactor containing the said catalyst layer. Described is a carrier with a catalytic coating, having at least one porous and cavity-containing catalyst layer, where the cavity consists of random voids with size greater than 5 mcm in at least two dimensions or with cross-sectional area of at least 10 mcm2. Described is a method of producing the said carrier, comprising a) preparing a carrier substrate, b) if needed, depositing an adhesion improving layer, c) spraying a suspension with at least 30% content of solid substance containing a catalytically active substance with average diameter of at least 5 mcm and/or precursor thereof and, if needed, an additional component of a catalytically active layer, and d) if needed, repeating step c) once or more. Described is a rector with a surface intended for coating, having at least one carrier with a catalytic coating described above. Described is use of the carrier in a method for catalytic oxidation of aliphatic compounds, in a method for oxidation of xylene and/or naphthalene to phthalic acid, in a method for oxidative coupling of acetic acid and ethane to form vinyl acetate using oxygen, in a method for catalytic hydrogenation of organic compounds and in a method for converting synthetic gas.
EFFECT: catalytic coatings are characterised by high adhesion strength of layers, having stability, negligible tolerance on layer thickness and mass-transfer resistance and can be universally used in multiple catalyst systems.
