Device and working method for chain cycle reaction hydrogen production and co-separation of carbon dioxide

Abstract

The invention discloses a device for synergistically separating carbon dioxide by chain cycle reaction for hydrogen production, comprising a fuel reactor, a hydrogen production reactor, an air reactor, a gas-solid separator, a partition plate, a first material leg, and a return riser and the second dipleg; 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, and the gas-solid separator is fixedly connected to the upper part of the air reactor; the air reactor and fuel react The reactor is connected through the first material leg; the fuel reactor is connected with the hydrogen production reactor through the return riser; the bottom of the hydrogen production reactor is connected with the bottom of the air reactor through the second material leg and the entrainment hole. The device effectively solves gas channeling between triple reactors, has high integration, simple structure, high heat transfer and utilization efficiency, and is easy to realize large scale. The invention also discloses a working method of the device, which can produce hydrogen through a chain cycle reaction with high efficiency and low energy consumption and cooperate to separate carbon dioxide.

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...
