MULTILAYERED CATALYTIC REACTOR Russian patent published in 2022 - IPC B01J8/04 

FIELD: chemistry.

SUBSTANCE: invention relates to multilayered catalytic converters (reactors). The multilayered catalytic reactor contains: a group of catalytic layers (4, 5, 6), through which sequential passage of technological gas is provided, from first catalytic layer (4) to last catalytic layer (6) of the specified group; intermediate heat exchanger (7) located between first catalytic layer (4) and second catalytic layer (5) of the specified group, and made for heat isolation from technological gas coming out from the first layer, before it comes into the second layer. At the same time, last catalytic layer (6) of the specified group is adiabatic and is made of fine catalyst particles, a size of which does not exceed 2 mm, and each of catalytic layers (4, 5, 6) contains one gas distributor and at least one gas collector, located so that the technological gas stream passes through the catalytic layer in a radial or axial-radial direction. Moreover, only last catalytic layer (6) of the specified group is made of a catalyst consisting of fine particles, and the other catalytic layer(s) is (are) made of a catalyst consisting of larger particles.

EFFECT: improvement of the operation efficiency and yield of a conversion process product, while minimizing reactor pressure drop.
