Wheat straw was pretreated with either CaO or CaO to improve biohydrogen production. Both CaO and CaO pretreatments improved the biodegradability of the wheat straw. CaO pretreatment raised the H yield by between 48.8 and 163.9% at CaO contents ranging from 2 to 4%. The highest H yield [144 mL/g total solid (TS)] was obtained at 121 °C and 6% CaO. In addition, the highest H yield from wheat straw pretreated at the same temperature and dosage of CaO was 71.8 mL/g TS, which was higher than that of the control group (43.2 mL/g TS), with hot water (121 °C) treatment. Considering pretreatment costs and H production potential, CaO was a better pretreatment agent than CaO.
用氧化钙（CaO）对小麦秸秆进行预处理以提高生物制氢产量。氧化钙预处理均提高了小麦秸秆的生物降解性。在氧化钙含量为2%至4%的范围内，氧化钙预处理使氢气产量提高了48.8%至163.9%。在121°C和6%氧化钙的条件下获得了最高氢气产量[144毫升/克总固体（TS）]。此外，在相同温度和氧化钙用量下预处理的小麦秸秆的最高氢气产量为71.8毫升/克TS，高于对照组（43.2毫升/克TS）经热水（121°C）处理后的产量。考虑到预处理成本和产氢潜力，氧化钙是比氧化钙更好的预处理剂。
