Abstract

Disclosed is a catalytic distillation tower reaction zone structure, and a reaction zone consists of a catalyst tray and a separation tower tray in alternating arrangement, and the catalyst tray is partitioned into down-flow zones, a catalyst filling zone and a vapor phase channel by a plurality of vertical baffles; and the catalyst filling zone is composed of a horizontal baffle positioned at the bottom part, a horizontal support plate on the horizontal baffle at the bottom part, and a semi-enclosed space between the plurality of vertical baffles and part of tower walls; the two down-flow zones are formed between part of vertical baffles and near tower walls, and the vapor phase channel is formed between the rest part of vertical baffles and near tower walls or between the vertical baffles. The catalyst is filled in the semi-enclosed space enclosed by the vertical baffles, part of tower walls and the support plate, the space between the baffle at the bottom part and the support plate is communicated with the separation tower tray on a catalyst bed through the down-flow zones, and is communicated with the catalyst bed through an opening or a gap of the support plate.

Description

technical field

[0001] The invention relates to a reaction section structure of a catalytic distillation tower capable of carrying out catalytic reaction and distillation separation at the same time, that is, the loading mode of the catalyst in the catalytic distillation tower. Background technique

[0002] Catalytic distillation technology is a chemical technology that simultaneously carries out the catalytic reaction process and the product separation process in a catalytic distillation tower, and realizes the separation of products and reactants while the reaction is in progress. It has the advantages of less equipment, low investment, simplified process, and energy It has the advantages of low consumption, high reaction conversion rate, ability to break the chemical equilibrium limit, high efficiency of reaction heat utilization, and convenient operation and control.

[0003] The catalytic distillation column generally includes three parts: the upper rectification sectio...
