CATALYTIC REACTION UNIT AND REACTION DISTILLATION COLUMN Russian patent published in 2024 - IPC B01D3/14 B01D3/24 B01J8/04 

FIELD: chemical engineering.

SUBSTANCE: invention relates to a catalytic reaction unit comprising a plurality of catalyst stack layers arranged vertically, each layer being respectively filled with solid catalyst (10), and an inclined surface located on the top of the corresponding solid catalyst (10) between adjacent layers of the catalyst stack; an auxiliary liquid phase supply unit, which is located above the uppermost layer of the catalyst stack, so that liquid phase feed can be introduced into the layer of the catalyst stack, and the liquid phase feed is directed by an inclined surface to sequentially enter each layer from top to bottom; an auxiliary gas phase supply unit, which is located between the layer of the catalyst package of the upper layer and the inclined surface of the next layer, while the gas-phase supply of each layer enters the layer from bottom to top, and gas-phase channel (13), which is relatively isolated from the auxiliary gas phase supply unit, with In this case, the gas-phase product formed after the reaction of gas-phase feed and liquid-phase feed in the layer of the catalyst package enters directly into gas-phase channel (13). The invention also concerns reaction distillation column (1).

EFFECT: improved efficiency of conversion of chemicals and selectivity for the target product.
