Hydrogen production device for low-temperature catalytic decomposition of ammonia gas

Abstract

The hydrogen production device comprises a gas inlet pipe, an outer shell, a heat preservation layer, an inner shell A, an outer layer heater, an inner shell B, an inner shell C, an inner layer heater, a power plug and an ammonia gas catalytic cracker, the outer shell is of a cylindrical structure, the gas inlet pipe is welded to the outer shell, the outer shell is filled with the heat preservation layer, and the outer shell is welded to the inner layer heater. The heat preservation layer is pearlite, the outer layer heater is fixed between the inner shell A and the inner shell B, and an airflow channel is formed between the inner shell B and the inner shell C; and the inner-layer heater is fixed between the inner shell C and the ammonia gas catalytic cracker. Compared with the prior art, the device has the advantages that the whole structure is compact, modular design is achieved, and the device is efficient, environmentally friendly and safe.

Description

technical field [0001] The invention relates to the field of new energy utilization, in particular to a hydrogen production device for low-temperature catalytic decomposition of ammonia gas. Background technique [0002] Hydrogen is the most human-friendly energy among all energy sources. It is clean, high energy density, easily accessible, renewable, and the more it is used, the cheaper it is. The product of direct combustion of hydrogen or power generation through fuel cells is water, which can achieve true zero carbon emissions and cause no pollution to the environment, so it is known as the ultimate energy source. [0003] As the largest carbon dioxide emitter, China faces many challenges on the road to carbon neutrality. The most important application scenarios of hydrogen energy in the future are in the field of transportation. Compared with fuel vehicles, hydrogen fuel electric vehicles and hydrogen diesel locomotives can achieve zero carbon emissions; It has inhere...

AI Technical Summary

Problems solved by technology

[0007]For hydrogen fuel electric vehicles and hydrogen internal combustion locomotives, the conventional practice is to directly refuel high-pressure hydrogen or liquid hydrogen at hydrogen refueling stations as fuel for cars or trucks , no matter from the aspect of driving on the road or parking in the parking lot, there are great potential safety hazards. Once the hydrogen leaks, it is very easy to cause an explosion accident
