Anaerobic digestion techniques, which are widely used to convert biogas for organic waste, (is typically 50~70%CH4With 20
~40%CO2), this method also can produce renewable energy other than helping to reduce organic waste to environment bring risk,
And reduce greenhouse gas emission.If to the CO in biogas2It separated, stored and is utilized, not only can get biological methane, used
In the imbalance between supply and demand problem for alleviating natural gas, CO can also be realized2Negative emission.Bio-natural gas is prepared by raw material of biogas
Critical issue is how CO is separated from biogas2, while reducing the influence to environment.
Common methane purification method mainly includes washing, pressure-variable adsorption, chemical absorbing and UF membrane etc..In contrast,
