Hydrogen production reactor device with gas replacement and efficient methane cracking carrier

Abstract

The invention discloses a hydrogen production reactor device with a gas replacement and efficient methane cracking carrier. The hydrogen production reactor device comprises a protection tube, a quartz tube, a diffuser, a supporting plate, an electric heater, a heat preservation layer, a nitrogen storage tank, a methane storage tank, a hydrogen storage tank, a spiral tube, a flow meter, a connecting base B, a carbon discharging mechanism, a connecting base A, a control circuit board and a catalyst which are installed together, wherein the methane cracking carrier is one of molten salt and fused salt. According to the invention, hydrogen is produced by gradually cracking methane, air in the hydrogen production reactor is replaced by gas, compared with a vacuum pump for pumping gas, the structure is simple, the equipment investment cost is reduced under the condition that the amount of carbon dioxide is reduced, the methane cracking carrier is selected as a molten alloy or a molten salt substance, and the methane cracking temperature can be reduced. Due to the catalytic activity of the methane cracking carrier, the hydrogen production rate of the cracked methane is better than that of the original liquid tin serving as a cracking carrier. The methane vent hole of the diffuser is designed to be a round hole, so that the gas inlet inhibition effect is avoided, the methane gas inlet rate is increased, and the productivity is improved.

Description

technical field [0001] The invention relates to the technical field of hydrogen production, in particular to a hydrogen production reactor device with gas replacement and high-efficiency methane cracking carrier. Background technique [0002] Due to the sharp increase in global energy demand, non-renewable energy sources such as fossil fuels are facing the danger of depletion, and the impact of fossil fuels on the environment cannot be ignored. Therefore, the development and utilization of new energy sources has become an increasingly urgent requirement. Among many new energy fuels, hydrogen, as an energy fuel, is considered as an ideal clean and high-energy fuel, and has attracted more and more attention. However, due to the high production cost of hydrogen, it is still difficult to use hydrogen energy in large quantities in life and production. Therefore, the research and development of more advanced new hydrogen production process technology is an important guarantee to...

AI Technical Summary

Problems solved by technology

However, due to the investment of vacuum pumps, the cost of equipment investment is increased; the use of liquid metal (tin or tin compounds) as the carrier for methane cracking is relatively expensive; the diffuser adopts a microporous structure, which has a certain inhibitory effect on the intake of methane

In summary, there is still room for improvement in the existing liquid metal pyrolysis methane hydrogen production reactor with catalytic function
