Biohydrogen production in an anaerobic fluidized granular bed bioreactor was strongly dependent on temperature and effluent recycle rates. At 45 °C as the effluent recycle rate was increased from 1.3 to 3.5 L/min, the total H₂ output for the bioreactor increased from 10.6 to 43.2 L/h. Volumetric H(2) productivity also increased from 2.1 to 8.7 L H₂/L/h. At 70°C as the effluent recycle was increased from 1.3 to 3.5 L/min, the total H₂ output for the bioreactor increased from 13.8 to 73.8L/h. At 70 °C volumetric H(2) productivities increased from 2.8 to 14.8L H₂/L/h as the effluent recycle rate was increased from 1.3 to 3.5 L/min. At 45 °C % H₂ was 45% and reached 67% at 70 °C. Maximum hydrogen yields at 45 °C were 1.24 and 2.2 mol H₂/mol glucose at 70 °C.
在厌氧流化床生物反应器中，生物制氢强烈依赖于温度和出水回流率。在 45°C 时，当出水回流率从 1.3 L/min 增加到 3.5 L/min 时，生物反应器的总氢气产量从 10.6 L/h 增加到 43.2 L/h。体积氢气生产率也从 2.1 L H₂/L/h 增加到 8.7 L H₂/L/h。在 70°C 时，当出水回流率从 1.3 L/min 增加到 3.5 L/min 时，生物反应器的总氢气产量从 13.8 L/h 增加到 73.8 L/h。在 70°C 时，当出水回流率从 1.3 L/min 增加到 3.5 L/min 时，体积氢气生产率从 2.8 L H₂/L/h 增加到 14.8 L H₂/L/h。在 45°C 时，H₂的百分比为 45%，在 70°C 时达到 67%。在 45°C 时，最大的氢气产率为 1.24 和 2.2 mol H₂/mol 葡萄糖，在 70°C 时。
