CATALYST FOR OXIDIZATION OF THE VANADIUM OXIDE PARTICLES IN THE GASEOUS PHASE WITH THE CERTAIN SIZE DISTRIBUTION Russian patent published in 2008 - IPC B01J23/22 B01J21/06 B01J27/198 B01J23/16 B01J23/04 B01J37/02 C07C51/265 C07C51/31

Abstract RU 2314867 C2

FIELD: chemical industry; non-ferrous metallurgy industry; other industries; methods of production of the catalyst for oxidization of the vanadium oxide particles in the gaseous phase with the definite size distribution.

SUBSTANCE: the invention is pertaining to the method of production of the catalyst for oxidization in the gaseous phase of the vanadium oxide particles with the definite size distribution. The invention describes the method of production of the catalyst for oxidization in the gaseous phase, at which on the fluidized inert carrier they deposit the suspension of TiO₂ and V₂O₅ particles, in which, at least, 90 volumetric % of the particles of V₂O₅ have the diameter of 20 microns or less and, at least, 95 volumetric % of the particles of V₂O₅ have the diameter of 30 microns or less. The technical result of the invention is that the certain particle-size distribution allows to achieve the high efficiency of the coating.

EFFECT: the invention allows to achieve the high efficiency of the coating.
