Pilot tests of sequential dark and photo fermentation H production were for the first time conducted in a 11 m reactor (3 m for dark and 8 m 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 m/d with 68% H content, contributed by dark unit at 7.5 m-H/m-d and by photo unit at 4.7 m/m-d. Large variation was noted for H 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.
首次在 11m 反应器（3m 用于黑暗发酵室，8m 用于光发酵室）中进行了序贯黑暗和光发酵制氢的初步试验。安装并测试了一个组合的太阳能和发光二极管照明系统和一个热控制系统。在黑暗发酵单元维持在 pH4.5 和 35°C 以及光发酵单元维持在 pH7.0 和 30°C 的条件下，使用水解玉米秸秆作为底物，整体沼气产生率达到 87.8±3.8m/d，其中 68%的 H 含量来自黑暗单元，产率为 7.5m-H/m-d，来自光单元的产率为 4.7m/m-d。在测试单元的不同隔室中，H 的产生率有很大的变化，这表明与大型反应器操作相关的混合不良、冲洗和其他非均相性会产生不利影响。
