METHOD OF MANUFACTURING A BLOCK REGENERATIVE PRODUCT Russian patent published in 2020 - IPC B01J20/32 B01J20/06 B29C53/24 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to production of block regenerative products based on alkali metal oxide compounds applied on a porous substrate and intended for regenerative cartridges. Disclosed is a method of producing a block regenerative product involving treatment of an initial regenerative product in the form of a tape containing reinforcing material impregnated with an active component in form of an alkali metal superoxide, preferably potassium or sodium, by acting on it with forming corrugating tool in mold with subsequent thermal stabilization. Initial regenerative product is preliminarily cut into preforms of predominantly rectangular shape, folding the preforms into a stack and subjecting the stack of preforms to molding by means of a sealing action with a forming corrugating tool at specific pressure of 10.0 to 60.0 MPa and subsequent holding under pressure for 0.15 to 5 minutes to produce corrugated plates, after which unit is assembled from corrugated plates by superimposing them on each other, wherein the plates, either even or odd, during laying are oriented so that longitudinal corrugations of the projection in the "view from above" intersect with each other, and fixing the plates of the block by applying an inert gas-permeable shell on its side surface.

EFFECT: invention simplifies the technology of producing a regenerative product in the form of profiled plates for channel units.
