CATALYTIC ELEMENT OF A REGULAR CELLULAR STRUCTURE FOR HETEROGENEOUS REACTIONS

摘要

FIELD: organic synthesis. ;SUBSTANCE: invention relates to catalytic elements of a regular cellular structure for heterogeneous reactions, for example, for the processes of cleaning waste gases of enterprises, selective reduction of nitrogen and oxygen oxides, ozone decomposition, the process of dehydrogenation of lower alkanes, alkenes, arylalkanes in a stationary catalyst layer in order to obtain the corresponding alkenes, alkadienes, aryl alkenes. A catalytic element is described for heterogeneous reactions involving deep oxidation of hydrocarbons, carbon monoxide, made in the form of a block of a regular honeycomb structure with rectangular honeycomb channels made of a catalytically active mass including an active component, aluminum oxide. As a precursor of aluminum oxide, a mixture of an aluminum compound with the formula Al2O3·nH2O, where 0.3≤n≤1.5, obtained by rapid partial dehydration of hydrargillite and aluminum oxide powder in a ratio of 20-80 wt. %, Al2O3·nH2O, where 0.3≤n≤1.5 and 80-20, wt. %, aluminum oxide powder, while the channel walls have open transport pores with a size of 50-500 nm in an amount of 35-70% of the total pore volume, as an active component includes a metal or a metal compound selected from the group: manganese, chromium, copper, iron or a mixture of them. ;EFFECT: development of catalytic elements for heterogeneous reactions in the form of blocks of a regular cellular structure from a catalytically active mass with high thermal stability, mechanical strength while maintaining high activity and the development of a simple method for their production, which makes it possible to significantly expand the use of block cellular catalysts in various chemical processes. ;20 cl, 2 tbl, 3 dwg, 5 ex
