The effect of the temperature (25 and 35 degrees C), the hydraulic retention time, HRT, (12 and 24 h) and initial substrate concentration on hydrogen production from Tequila vinasse was studied using a sequencing batch reactor. When 25 degrees C and 12-h HRT were applied, only insignificant biogas quantities were produced; however, using 24 h of HRT and temperatures of 25 and 35 degrees C, biogas containing hydrogen was produced. A maximum volumetric hydrogen production rate of 50.5 mL H(2) L(-1) h(-1) (48 mmol H(2) L(reactor)(-1) d(-1)) and an average hydrogen content in the biogas of 29.2+/-8.8% were obtained when the reactor was fed with 3 g COD L(-1), at 35 degrees C and 12-h HRT. Methane formation was observed when the longer HRT was applied. Results demonstrated the feasibility to produce hydrogen from this waste without a previous pre-treatment.
采用序批式反应器研究了温度（25 和 35°C）、水力停留时间（HRT）（12 和 24 h）和初始基质浓度对龙舌兰酒废渣产氢的影响。当应用 25°C 和 12 h 的 HRT 时，仅产生了少量的沼气；然而，当应用 24 h 的 HRT 和 25 和 35°C 的温度时，产生了含有氢气的沼气。当以 3 g COD L(-1)、35°C 和 12 h 的 HRT 进料时，最大体积产氢率为 50.5 mL H(2) L(-1) h(-1)（48 mmol H(2) L(reactor)(-1) d(-1)），沼气中氢气的平均含量为 29.2+/-8.8%。当应用较长的 HRT 时，观察到了甲烷的形成。结果表明，无需预先进行预处理即可从这种废物中生产氢气。
