This study investigated the use of calcined-lime mud from papermaking process (CLMP) pretreatment to improve fermentative hydrogen yields from corn-bran residue (CBR). CBR samples were pretreated with different concentrations (0-15 g/L) of CLMP at 55°C for 48 h, prior to the thermophilic fermentation with heat-treated anaerobic sludge inoculum. The maximum hydrogen yield (MHY) of 338.91 ml/g-VS was produced from the CBR pretreated with 10 g/L CLMP, with the corresponding lag-phase time of 8.24h. Hydrogen yield increments increased from 27.76% to 48.07%, compared to the control. The CLMP hydrolyzed more cellulose, which provided adequate substrates for hydrogen production.
本研究考察了造纸过程中煅烧石灰泥(CLMP)预处理对提高玉米秸秆残渣(CBR)发酵产氢的效果。将 CBR 样品在 55°C 下用不同浓度(0-15 g/L)的 CLMP 预处理 48 小时,然后用热处理的厌氧污泥接种物进行高温发酵。用 10 g/L CLMP 预处理的 CBR 的最大产氢量(MHY)为 338.91 ml/g-VS,相应的迟滞期为 8.24 h。与对照相比,氢产量增加了 27.76%至 48.07%。CLMP 水解了更多的纤维素,为产氢提供了充足的底物。
