MULTILAYER CATALYTIC REACTOR WITH MIXING DEVICE Russian patent published in 2021 - IPC B01J8/04 

FIELD: mixing.

SUBSTANCE: invention relates to a multilayer catalytic reactor having a cylindrical shape and containing a mixing device mounted between two catalytic layers in the reactor, wherein the above-mentioned mixing device has an annular outer rim, which corresponds an inner reactor wall, and the mixing device contains: collecting means located in a collector section for collecting fluid from a catalytic layer located upstream; mixing means located in a mixing section for mixing collected fluid containing guide blades and guide ramps; and draining means located in a drain section for draining a fluid mixture to a catalytic layer located downstream; the collector section, the mixing section and the drain section are located outside a central part of an annular cross-section of the reactor. In the claimed solution, a method for mixing is disclosed using such a mixing device in catalytic reactors.

EFFECT: invention allows for providing highly effective mixing and redistributing when occupying the minimum volume of the reactor and creating a limited pressure loss.
