Description

Technical field[0001]The invention relates to the technical field of hydrogen production, and more specifically, to a chain reaction hydrogen production system and a hydrogen production method starting from a chain combustion reaction mechanism.Background technique[0002]CO2Are the main greenhouse gases that cause global warming, while traditional fossil fuel combustion produces CO2Main 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 are paying more and more attention to the development and utilization of renewable energy. As an ideal secondary energy source, hydrogen energy is clean, pollution-free, and has high combustion calorific value. It is regarded as the most promising energy source in the future. Due to the declining fossil energy resources and the increasing concern about the environmental impacts caused by global warming, the energy industry needs to find a new solution to ...

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
