Abstract

The invention provides a solid fuel chemical-looping gasification hydrogen production system and method. The solid fuel chemical-looping gasification hydrogen production system is characterized by comprising an air reactor, wherein the air reactor is connected with a first gas-solid separation device; the first gas-solid separation device is connected with a fuel reactor; the fuel reactor is connected with a second gas-solid separation device; a gas outlet of the second gas-solid separation device is connected with a synthetic gas converter; the synthetic gas converter is connected with a CO2 adsorption unit; a discharge port of the CO2 adsorption unit is connected with an H2 processing unit; an outlet of the CO2 adsorption unit is connected with a third gas-solid separation device; a CaCO3 solid outlet of the third gas-solid separation device is connected with a calcining furnace; the calcining furnace is connected with a fourth gas-solid separation device; a gas outlet of the fourth gas-solid separation device is connected with a CO2 processing unit; a solid outlet of the fourth gas-solid separation device is connected with a CaO storage tank; and the CaO storage tank is connected with the CO2 adsorption unit. The system can implement near zero discharge of CO2 in the hydrogen production process, and thus, reduces the influence of greenhouse gas on the environment.

Description

technical field [0001] The invention relates to a solid fuel chemical loop gasification hydrogen production system and method, in particular to a hydrogen production system with CO 2 Captured solid fuel chemical loop gasification hydrogen production system and method. Background technique [0002] As a clean new energy source, hydrogen can not only be used as a fuel, but also an important chemical raw material. When hydrogen undergoes energy conversion, the product is water, which can realize zero discharge of pollutants in the true sense. There are many methods of hydrogen production in the published and authorized patents. The patent "coal and biomass co-supercritical water catalytic gasification hydrogen production device and method" discloses a coal and biomass co-supercritical water catalytic gasification Hydrogen device and method, the hydrogen content in the gas product increases, and the concentration of carbon dioxide in the gas product increases, and the carbon d...
