Catalytic combustion reactor

Abstract

The invention discloses a catalytic combustion reactor. The catalytic combustion reactor comprises a reaction container, a feeding pipe, a fan component, a filling mechanism and a heat conduction mechanism. The reaction container is provided with an exhaust port. The bottom end of the feeding pipe extends into the reaction container, the top end of the feeding pipe extends out of the reaction container, and a first opening for introducing methanol, a second opening for introducing hydrogen and a third opening for introducing air are respectively formed at different positions of the feeding pipe. Fan blades of the fan component are arranged in the container and are used for introducing gas into the reaction container along the feeding pipe. The filling mechanism is used for filling a catalyst for catalyzing methanol combustion. The heat conduction mechanism is in heat conduction connection with the filling mechanism. The heat conduction mechanism is internally used for bearing and circulating a heat carrier and heating the heat carrier. A gas circuit in the reaction container sequentially passes through the bottom end of the feeding pipe, the filling mechanism and the exhaust port.The catalytic combustion reactor can conveniently recycle hydrogen-containing waste gas so as to save energy.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to catalytic combustion reactors. Background technique [0002] The methanol cracking hydrogen production process is as follows: Methanol is preheated by the vaporizer, then vaporized by the superheater and then enters the cracking reactor. temperature. The cracking reactor is filled with a cracking catalyst for catalytic steam methanol cracking. Under the action of the cracking catalyst, catalytic cracking reaction and catalytic conversion reaction occur simultaneously to obtain reformed gas mainly containing hydrogen and carbon dioxide (and a small amount of carbon monoxide and methane). [0003] Obviously, directly discharging the tail gas of the cracking reactor not only causes pollution, but also causes waste. Therefore, how to utilize this part of residual raw material conveniently is of great significance. Contents of the invention [0004] In order to overcome the defi...
