METHOD OF PRODUCING CATALYTIC MATERIALS BY 3D PRINTING METHOD Russian patent published in 2020 - IPC B01J35/02 B01J37/00 B29C64/00 

FIELD: chemistry.

SUBSTANCE: invention relates to production of catalysts by three-dimensional printing (3D printing). Disclosed is a method of producing catalytic materials by 3D printing based on ceramic powders and/or finely dispersed nanostructured powders with crystallite size close to X-ray amorphous crystalline structure of less than 5 nm, and production thereof involves the following steps: 1) preliminary computer simulation of hydrodynamic characteristics of catalyst layer for various versions of granules/pellets geometry and preset: geometry of reactor unit, reaction conditions - pressure, temperature, composition and speed of reaction flow; 2) selection of optimal version of size, shape and internal spatial structure of pore channels-pores of granules/pellets; 3) 3D design of optimized granules/pellets for 3D printing implementation; 4) 3D printing of optimized granules/pellets using one of the known methods.

EFFECT: invention enables to obtain catalytic materials by 3D printing method, having high catalytic activity due to complex branched geometry of channels-pores, high ratio of surface area to volume.
