Title:
METHOD FOR RECOVERING HYDROGEN FROM BIOMASS PYROLYSIS GAS
Document Type and Number:
WIPO Patent Application WO/2018/037481
Kind Code:
A1
Abstract:
The present invention provides a method for recovering hydrogen which not only is capable of efficiently recovering high concentration hydrogen gas by adsorbing and removing hydrocarbon gas such as carbon dioxide from biomass pyrolysis gas under a relatively low pressure but is also capable of storing the recovered high concentration hydrogen gas, preferably, in a cartridge type container that can be used as is as a hydrogen storing container for an apparatus equipped with a fuel cell. The method for recovering hydrogen includes a first purifying stage of purifying biomass pyrolysis gas and a second purifying stage of purifying the obtained purified gas under a pressure equal to or less than the pressure in the first purifying stage to recover gas that contains hydrogen, and further includes a hydrogen storing stage of feeding the gas containing hydrogen recovered in the second purifying stage into the predetermined container filled with a hydrogen storage alloy and storing high purity hydrogen.
