METHOD OF PREPARATION OF THE CATALYST Russian patent published in 2018 - IPC B01J37/03 B01J23/38 B01J21/04 B01J21/06 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of preparation of catalysts which can be used in processes of oxidative conversion of hydrocarbons and selective oxidation of oxygen-containing organic compounds, hydrogenation of carbon oxides and unsaturated carbon-carbon and carbon-heteroatomic bonds in organic substrates, hydrocracking of hydrocarbons. Catalyst is prepared by hydrolytic precipitation of oxides of platinum, ruthenium or rhodium on a carrier, placing the carrier in a metastable aqueous solution containing a chlorine-containing salt or complex of platinum, ruthenium or rhodium and a hydrolyzing agent at a temperature below 100 °C, which promote the acceleration of the hydrolysis of a salt or a complex of platinum, ruthenium or rhodium and the quantitative fixation of metal oxides on a carrier, followed by recovery of the carrier with applied platinum, ruthenium or rhodium oxides from the solution, air drying and reduction processes.

EFFECT: technical result consists in obtaining of a catalyst with a high dispersion of the active component particles.
