Process for solid-state methane fermentation of biomass materials and fermentation apparatus system therefor |
摘要 |
A process for producing a biogas by solid-state fermentation of a solid biomass material which comprises the steps of: (1) pelletizing the biomass material into pellets; (2) introducing the pellets into an acid fermentation zone; (3) subjecting the biomass material in the pellets to solid-state acid fermentation under facultative anaerobic conditions or under semi-aerobic conditions kept in an oxygen concentration of 0.01% to 5.0%; (4) densifying the pellets by compression to remove the oxygen from among the particles of the biomass material; (5) transferring the densified pellets into a methane fermentation zone; and (6) subjecting the biomass material in the densified pellets to methane fermentation in the methane fermentation zone under anaerobic conditions, and an apparatus system for producing a biogas by solid-state fermentation of a solid biomass material which comprises: an acid fermentation tank ( 7 ) having a means for pelletization ( 4 ) of the solid biomass material and an air inlet ( 25 ) with a movable valve; and a methane fermentation tank ( 11 ) having a pellet compressing means ( 12 ) connected to the acid fermentation tank ( 11 ) through a movable valve ( 9 ) for separation.
