Abstract

The invention discloses a device for realizing hydrogen production and carbon dioxide separation simultaneously through the chain type circulation reaction. The device comprises a fuel reactor, a hydrogen production reactor, an air reactor, a gas-solid separator, a partition board, a first dipleg, vertical return pipes and a second dipleg, wherein the fuel reactor is fixedly connected to the upper part of the air reactor; the hydrogen production reactor is fixedly connected to the lower part of the air reactor; the gas-solid separator is fixedly connected to the upper part of the air reactor; the air reactor and the fuel reactor are communicated through the first dipleg; the fuel reactor and the hydrogen production reactor are communicated through the vertical return pipes; and the bottom of the hydrogen production reactor and the bottom of the air reactor are communicated through the second dipleg and an entrainment hole. The device effectively solves the problem of gas mixing among the three reactors, is high in integration level, simple in structure and high in heat transfer and use efficiency, and upsizing is easy to realize. The invention further discloses a working method of the device. With the adoption of the method, hydrogen production and carbon dioxide separation can be realized simultaneously through the chain type circulation reaction with high efficiency and low energy consumption.

Description

technical field [0001] The invention relates to the technical fields of energy conversion and environmental protection, in particular to a device for producing hydrogen through a chain cycle reaction and synergistically separating carbon dioxide and a working method thereof. technical background [0002] Hydrogen energy is an efficient and clean energy with the characteristics of no pollution, storability, and high combustion calorific value. It also has the function of adjusting and compensating for other primary energy sources. In the energy system, it is expected to become the main terminal energy that is equally important and complementary to electricity, and is recognized as one of the most potential energy carriers in the future. At present, hydrogen energy is mainly obtained from fossil fuels such as coal, oil, and natural gas. Hydrogen production technologies mainly include coal gasification hydrogen production, natural gas reforming hydrogen production, and water el...
