High concentrations of corn stover (60 g/L) as the main substrate, through the dark fermentation and anaerobic digestion two-phase fermentation production of hydrogen and methane gas. In the dark fermentation hydrogen production stage, and to strengthen the strains in the fermentation process is studied, CTAB and ammonium bicarbonate and so on several process parameters on the effect of fermentation to produce hydrogen. Results show that the strain BacillusspFS2011 addition amount of 10% (v/v), CTAB concentration of 30 mg/L and the carbonic acid hydrogen ammonia concentration is 1.2 g/L of the optimal conditions, with corn stalk maximum yield of hydrogen and hydrogen production rate were 79.8 + / - 1.5 mlH2 / g - straw and 3.78 + / - 0.2 ml/hg - straw. In the methane-producing phase, fermented liquid hydrogen as the substrate to generate methane production from methane. Cumulative methane yield and maximum production rate of methane and COD removal rate is respectively 227 + / - 2.5 mlCH4 / g - COD, 436...
xiangying eagle analysis technology co., LTD., is determined by gas chromatograph XingyingGC7990plus high concentrations of straw combined with dark fermentation and anaerobic digestion combined hydrogen and methane gas, the result satisfied.
高浓度玉米秸秆(60g/L)作为产氢底物,通过暗发酵及厌氧消化两阶段发酵生产氢气和甲烷气。在暗发酵产氢阶段,考察和研究了发酵过程中菌种强化、CTAB和碳酸氢铵等几个过程参数对发酵产氢的影响。结果表明在菌株BacillusspFS2011添加量为10%(v/v)、CTAB浓度为30mg/L以及碳酸氢氨浓度为1.2g/L的最优条件下,得到高浓度玉米秸秆最大的氢气产量以及最大产氢速率分别为79.8±1.5mlH2/g-秸秆以及3.78±0.2ml/hg-秸秆。在产甲烷阶段,将氢发酵的废液作为产甲烷的底物生成甲烷。累积甲烷产量、最大产甲烷速率以及COD去除率分别为227±2.5mlCH4/g-COD、436....
