生物的物質の嫌気性発酵からのバイオガスの性質向上及び水素生成のための方法及び装置
Document Type and Number:
Japanese Patent JP6977972
Kind Code:
B2
Abstract:
Method and device for biogas upgrading and hydrogen production from anaerobic fermentation of biological material under production of energy rich gases selected among methane and hydrogen or a combination thereof. The method comprises addition of hydrogen gas to a fermentation step to enhance the methane: CO2 ratio in the raw biogas produced. At least part of the raw biogas is subjected to a step of sorption enhanced reforming without prior separation of CO2, using CaO as an absorbent to capture CO2 from the raw biogas as well as CO2 released in the reforming reaction. CaO is regenerated in an endothermic reaction using heat at least partially provided, directly or indirectly, by the bio-gas to be upgraded, thereby producing substantially pure hydrogen and substantially pure CO2.
