Description
Technical field
The present invention relates to waste utilization method and technology field, specially a kind of novel process that feces of livestock and poultry utilizes.
Background technique
Contain a large amount of organic matter in feces of livestock and poultry, these organic principles can produce based on methane by anaerobic fermentation
Fuel gas, methane is generally 60% in composition, while going back carbonated and a small amount of vapor, hydrogen sulfide, organic volatile
Object etc..It is using purification technique currently with most modes, such as pressure-variable adsorption, WATER-WASHING METHOD, amine washes method and embrane method Deng, according to state
Family's standard GB17820 natural gas and GB18047 compressed natural gas used as vehicle fuel standard purification are to pipe natural gas or natural gas used for automobile.
Summary of the invention
Technical problem solved by the invention is to provide a kind of novel process that feces of livestock and poultry utilizes, to solve above-mentioned back
The problems in scape technology.
Technical problem solved by the invention is realized using following technical scheme: a kind of novel work that feces of livestock and poultry utilizes
Skill, comprising the following steps:
Step (1): feces of livestock and poultry first passes through anaerobic fermentation, solid of the generated biogas by pre-processing, in raw material first
H in grain and the drop and biogas that condense out2S removing；
Step (2): enter decarburization psa unit after the biogas pressurization after desulfurization；Methane gas after purification enters steam methane
Reformation hydrogen production equipment,
Step (3): the discharge gas of Methane Steam Reforming equipment enters the pressure-swing absorption apparatus of special hydrogen purification,
Hydrogen purity is finally purified to 99.999%, then can be directly used for hydrogen energy automobile aerating by pressurization in hydrogenation stations.
The gas that shown Methane Steam Reforming equipment generates is 78% containing hydrogen volume score based on hydrogen,
Residual air body mainly based on carbon dioxide, contains a small amount of methane impurities simultaneously.
Be compared to open technology, there are following advantages by the present invention: the present invention by methane steam reforming technique to hydrogen,
