Description

technical field [0001] The invention relates to the technical field of hydrogen production, and more particularly, to a chain reaction hydrogen production system and a hydrogen production method based on a chain combustion reaction mechanism. Background technique [0002] CO 2 is the main greenhouse gas responsible for global warming, while traditional fossil fuel combustion produces CO 2 main source. At the same time, in order to reduce the damage to the human environment caused by pollutants generated in the process of energy use, people pay more and more attention to the development and utilization of renewable energy. As an ideal secondary energy, hydrogen energy is clean, non-polluting, and has a high calorific value. It is regarded as the energy with the most development potential in the future. Due to dwindling fossil energy resources and growing concerns about the environmental impact of global warming, the energy industry needs to find a new solution to overcome ...

AI Technical Summary

Problems solved by technology

The solid fuel hydrogen production process mainly includes raw material gasification, CO water vapor shift, pressure swing adsorption and waste heat recovery. Since the reversible reaction of CO water vapor shift is limited by thermodynamic equilibrium, the hydrogen production process generally has high energy consumption, low conversion rate and selectivity, and hydrogen Low purity, hydrogen needs subsequent product separation and purification

At present, cryogenic separation and pressure swing adsorption at home and abroad can convert the product H 2 Purified to more than 99%, but the process is complicated and the technical price is extremely expensive
