Pilot tests of sequential dark and photo fermentation H₂ production were for the first time conducted in a 11 m³ reactor (3 m³ for dark and 8 m³ for photo compartments). A combined solar and light-emitting diode illumination system and a thermal controlling system was installed and tested. With dark fermentation unit maintained at pH 4.5 and 35 °C and photo fermentation unit at pH 7.0 and 30 °C, the overall biogas production rate using hydrolyzed corn stover as substrate reached 87.8 ± 3.8 m³/d with 68% H₂ content, contributed by dark unit at 7.5 m³-H₂/m³-d and by photo unit at 4.7 m³/m³-d. Large variation was noted for H₂ production rate in different compartments of the tested units, revealing the adverse effects of poor mixing, washout, and other inhomogeneity associated with large reactor operations.

连续黑暗和照片发酵H的中间试验₂的产量分别为用于在11米进行的第一次³反应器（3米³为暗和8米³用于光隔室）。安装并测试了组合式太阳能和发光二极管照明系统以及热控制系统。在黑暗发酵装置的pH值保持在4.5和35°C的情况下，光发酵装置的pH值在7.0和30°C的情况下，以水解玉米秸秆为底物且H ₂含量为68％的沼气的总生产率达到87.8±3.8 m ³ / d ，由7.5 m ³ -H ₂ / m ³ -d的暗单元和由4.7 m ^3的照相单元贡献/ m ³ -d。注意到在测试单元的不同隔室中H _2的生产率有很大的变化，揭示了不良混合，冲洗和其他与大反应器操作相关的不均匀性的不利影响。
