METHOD FOR MANUFACTURING HIGHLY POROUS MATERIAL Russian patent published in 2023 - IPC B01J37/08 B01J37/06 B01J38/64 B01J25/02 B01J35/10 

FIELD: chemistry.

SUBSTANCE: production of porous catalysts used in industry in chemical reactors, as well as in batteries. The present invention relates to a process for the manufacture of a catalyst in the form of a highly porous plate, characterized by the preparation of a nickel-aluminum alloy by gradually heating a mixture of nickel and aluminum powders in a melting crucible to a temperature of 1,100°C, obtaining from a nickel-aluminum alloy powder from rapidly quenched particles on a rotating water-cooled drum, crushing the specified powder in a crusher to a fine powder and subsequent leaching of aluminum, in which the fine powder is mixed with an alkali metal salt, the resulting mixture is pressed into plates, the plates are sintered at a temperature 1000°C, after cooling, the alkali metal salt is removed by treating the plate with a 5% hydrochloric acid solution, the plates are washed and dried, while the activation of the resulting plates by leaching aluminum with a sodium hydroxide solution is carried out immediately before using the plate, and the nickel-aluminum alloy is prepared from a mixture of powders, containing 60 wt.% Al and 40 wt.% Ni, or from a mixture of powders containing 50 wt.% Al and 45 wt.% Ni, the rest is an activator, which is used as the following or several of the following metals: chromium, cobalt, palladium, ruthenium.

EFFECT: increasing the efficiency of using a catalyst in the form of a highly porous plate in chemical reactors and accumulators.
