Industrial crude hydrogen purification and hydrogen storage and release system and method based on organic liquid hydrogen storage medium

Abstract

The invention discloses an industrial crude hydrogen purification and hydrogen storage and release system and method for an organic liquid hydrogen storage medium, and belongs to the technical field of organic liquid hydrogen storage. The system comprises 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 dehydrogenation device and a hydrogen-rich hydrogen storage medium storage tank. The method comprises the steps of firstly, introducing an industrial crude hydrogen source into the gas compression device to compress the industrial crude hydrogen source, then introducing the compressed crude hydrogen source into the organic liquid hydrogen storage medium hydrogenation device to carry out catalytic hydrogenation, feeding a material subjected to catalytic hydrogenation into the hydrogen-rich hydrogen storage medium storage tank, feeding the material in the hydrogen-rich hydrogen storage medium storage tank into the hydrogen-rich hydrogen storage medium dehydrogenation device for dehydrogenation, and finally, discharging high-purity hydrogen from one outlet after passing through the hydrogen-rich hydrogen storage medium dehydrogenation device. Additional gas purification equipment is not needed, the purification problem of an impurity-containing industrial crude hydrogen source is solved, and high-purity hydrogen meeting the use standard can be output.

Description

technical field [0001] The invention belongs to the technical field of organic liquid hydrogen storage, and in particular relates to an industrial crude hydrogen purification and hydrogen storage and release system and method of an organic liquid hydrogen storage medium. 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 has ...
