Abstract

The invention discloses a hydrogen storage and release system and method for an organic liquid hydrogen storage medium and an industrial crude hydrogen source, and belongs to the technical field of organic liquid hydrogen storage. The system comprises a first gas purification device, a gas compression device, an organic liquid hydrogen storage medium hydrogenation device, an organic liquid hydrogen storage medium storage tank, a hydrogen-rich hydrogen storage medium storage tank, a hydrogen-rich hydrogen storage medium dehydrogenation device and a second gas purification device, an industrialcrude hydrogen source is introduced into the first gas purification device, is purified, then introduced into the gas compression device and is compressed, the compressed hydrogen source enters the organic liquid hydrogen storage medium hydrogenation device, is subjected to catalytic hydrogenation, is fed into a hydrogen-rich hydrogen storage medium storage tank, then is fed into the hydrogen-richhydrogen storage medium dehydrogenation device, and is subjected to dehydrogenation, and hydrogen obtained after passing through the hydrogen-rich hydrogen storage medium dehydrogenation device enters the second gas purification device and is purified again to obtain high-purity hydrogen. The high-purity hydrogen is obtained, and meanwhile, the problems of purification of an industrial crude hydrogen source and safe storage and transportation of hydrogen can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of organic liquid hydrogen storage, and in particular relates to a hydrogen storage and discharge system and method based on an organic liquid hydrogen storage medium and an industrial crude hydrogen source. Background technique [0002] Hydrogen is an environmentally attractive fuel and a viable energy carrier for connecting a range of energy forms to various end uses in the future. The mass energy density of hydrogen is 120kJ g -1 , is three times that of gasoline. It can be powered directly by combustion in an internal combustion engine, or it can efficiently power an electric motor through a fuel cell, and the only product in the process is water, so it does not cause environmental pollution or increase greenhouse gas emissions. The industrial sources of hydrogen are very extensive, and large-scale industrial hydrogen production has been going on for decades. In China, a strong chemical industry also ...
