Catalytic reaction unit and reactive distillation column

Abstract

A catalytic reaction unit has a plurality of catalyst bed layers arranged vertically, each of the catalyst bed layers being filled with a solid catalyst, and an inclined surface on the upper part of the corresponding solid catalyst arranged between adjacent catalyst bed layers; a liquid phase feeding subunit arranged above the topmost 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 arranged between the catalyst bed layer of an upper layer and the inclined surface of the next layer, and a gas phase channel relatively isolated from the gas phase feeding subunit. The gas phase product generated after the gas-phase feed and the liquid phase feed react in the catalyst bed layer directly enters the gas phase channel.
