DEVICE FOR COLLECTION OF GASEOUS FLUID MEDIUM FOR RADIAL REACTOR Russian patent published in 2019 - IPC B01J8/12 B01J19/24 

FIELD: various technological processes.

SUBSTANCE: invention relates to device for collection of gaseous fluid medium for installations operating on movable layer with radial circulation of raw material, as well as a reactor with a radial layer containing such a device, and a method for catalytic conversion of hydrocarbon material using such a reactor. Device comprises a vertical cylindrical grid which is permeable for gaseous fluid medium and particle-impermeable catalyst, and a vertical cylindrical pipe which is permeable for gaseous fluid medium and a catalyst-impermeable catalyst and which is fixed on the mesh and is concentric with respect to the mesh. At that, pipe contains one or several zones permeable for gaseous fluid medium, and multiple zones of restricted permeability for gaseous fluid medium in comparison with zone permeable for gaseous fluid medium, wherein each zone of limited permeability has less porosity than the permeable zone, wherein the porosity of the zone is defined as the ratio between the total permeable area of the zone and the total unfolded area of the zone.

EFFECT: invention provides a pure head loss exceeding loss of pressure of gaseous fluid medium along its path in catalytic layer and uniform distribution of raw material, as well as reduced blocking of catalyst on grid.
