| 摘要 |
The present invention refers to the field of green technology, with the production of biogas from plant biomass in reactors operated in a semi- continuous or continuous process. The present invention relates to a process for producing biogas comprising the steps of: (a) pretreatment of plant biomass by steam explosion; (b) hydrolysis of the material treated in step (a) by hydrolytic bacteria, with or without addition of cellulase enzymes, in conjunction or not with xylanase enzymes; and (c) anaerobic digestion of the material hydrolyzed in step (b); wherein steps (a), (b), and (c) are carried out in separate reactors and the product of step (c) is biogas. The present invention further relates to a system for carrying out the process for producing biogas of the present invention, which comprises: (i) first reactor for the pretreatment of plant biomass by steam explosion; (ii) second reactor for the hydrolysis of the material treated in step (i) by hydrolytic bacteria, with or without addition of cellulase enzymes, in conjunction or not with xylanase enzymes; and (iii) third reactor for anaerobic digestion of the material hydrolyzed in step (ii). |
