摘要： A hydrogen storage cartridge small and lightweight allows storage and discharge of hydrogen at low pressure and normal temperature. It also can effectively absorb the volume expansion accompanying atomization of a hydrogen storage alloy that occurs due to repeated storage and discharge of hydrogen, and therefore a hydrogen storage cartridge (A) is provided in which deformation due to repeated use, and in particular irregular deformation, extremely unlikely, also it can effectively avoid hydrogen storage irregularities of the hydrogen storage alloy. The hydrogen storage cartridge (A) is used for storage of hydrogen contained in biomass thermal decomposition gas, wherein the material of the hydrogen storage cartridge (A) is pure titanium, and the hydrogen storage cartridge (A) includes in the interior space (1), as a hydrogen storage alloy, at least one hydrogen storage alloy selected from the group comprising lanthanum mischmetal/nickel, titanium/iron, calcium/nickel, and lanthanum/nickel.

摘要： Provided is a hydrogen recovery method such that highly concentrated hydrogen gas can be obtained efficiently by adsorbing and removing hydrocarbon gas such as carbon dioxide, carbon monoxide, and methane, using a relatively low pressure, from pyrolysis gas obtained by heat treating biomass. The present invention is the method for recovering hydrogen from pyrolysis gas obtained by heat treating biomass, characterized by including: a first purifying step of adsorbing and removing gas that mainly includes carbon dioxide under pressure from the pyrolysis gas to purify the pyrolysis gas; and a second purifying step of further adsorbing and removing gas that includes carbon dioxide under pressure from purified gas obtained by the first purifying step at a pressure lower than the pressure in the first purifying step to purify the purified gas in order to recover hydrogen from the purified gas.

摘要： A method for recovering hydrogen which 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, and 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 includes a first purifying stare 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 container filled with a hydrogen storage alloy and storing high purity hydrogen.

摘要： A gasification apparatus can produce hydrogen-containing gas from biomass with high thermal efficiency at low costs without severe trouble caused by tar generated by pyrolyzing the biomass, while maximizing the gasification rate of the tar. The gasification apparatus includes a biomass pyrolyzing zone for heating biomass in a non-oxidizing atmosphere, and a gas reforming zone for heating the resulting pyrolyzed gas in the presence of steam. A plurality of preheated granules and/or lumps is moved from the gas reforming zone to the biomass pyrolyzing zone, the apparatus reforms the gas generated by pyrolyzing the biomass and pyrolyzes the biomass, using the heat of the granules and/or lumps. The biomass pyrolyzing zone and the gas reforming zone is provided in a single vessel, and at least one partitioning plate is provided between the biomass pyrolyzing zone and the gas reforming zone.
