Title:
CATALYTIC REACTION UNIT AND REACTIVE DISTILLATION COLUMN
Document Type and Number:
WIPO Patent Application WO/2022/083688
Kind Code:
A1
Abstract:
A catalytic reaction unit, comprising: a plurality of catalyst bed layers arranged vertically, each of the catalyst bed layers being filled with a solid catalyst (10), respectively, and an inclined surface on the upper part of the corresponding solid catalyst (10) being arranged between adjacent catalyst bed layers; a liquid phase feeding subunit, which is arranged above the topmost catalyst bed layer, so that liquid phase feed can be introduced into the catalyst bed layer, and the liquid phase feed is guided by the inclined surface to sequentially enter each catalyst bed layer from top to bottom; a gas phase feeding subunit, which is arranged between the catalyst bed layer of an upper layer and the inclined surface of the next layer, the gas phase feed of each layer entering the catalyst bed layer in an upward manner; and a gas phase channel (13), which is relatively isolated from the gas phase feeding subunit, a gas phase product generated after the gas-phase feed and the liquid phase feed react in the catalyst bed layer directly entering the gas phase channel (13). A reactive distillation column (1), in which the catalytic reaction unit is used, and the reactive distillation column (1) has a multilayer plate tower structure.
