Abstract

The invention discloses a device for producing hydrogen with solid fuel chemical chains. The device comprises a fuel reactor (1), a steam reactor (2), an air reactor (3), a first cyclone separator (5) and a second cyclone separator (6), a first solid fuel feed port (1C) in the middle of the fuel reactor (1) is connected with a feed bin (4), an oxygen carrier inlet (1E) is communicated with an outlet in the bottom of the first cyclone separator (5), and a first solid product outlet (1A) is communicated with the top of the steam reactor (2); the bottom of the steam reactor (2) is provided with a steam inlet (2C), the top of the steam reactor (2) is provided with a gas product outlet (2B), the gas product outlet (2B) is communicated with the second cyclone separator (6), and a second solid product outlet (2A) is communicated with the bottom of the air reactor (3); the bottom of the air reactor (3) is provided with an air inlet (3A), and a product outlet (3B) is communicated with an inlet of the first cyclone separator (5). The device has the advantages that pure oxygen is not needed in the hydrogen production process, the operation cost is low, and the reaction speed is high.

Description

technical field [0001] The invention belongs to a solid fuel gasification method, in particular to a device and application for solid fuel chemical chain hydrogen production. Background technique [0002] Production of high-concentration CO by traditional gasification technology 2 and H 2 , need to go through O 2 -H 2 O gasification, water gas shift, gas separation and purification steps to obtain the product gas, the process requires pure oxygen, long process, high investment cost, low hydrogen production efficiency, high production cost. [0003] Chemical chain conversion refers to the transfer of oxygen from the oxygen supply reactor to the fuel in the oxygen production reactor by means of the action of the oxygen carrier, so as to realize the isolation of the oxygen-gaining atmosphere and the oxygen-losing atmosphere, reflecting the advantages of separation; on the other hand , the oxygen carrier can carry a certain amount of heat, which acts as a heat carrier and ha...
