Abstract:
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.

Claim (Index 10):
The method according to  claim 1 , wherein the pyrolysis gas encompasses gas obtained by steam-reforming the pyrolysis gas obtained by heat-treating the biomass.
