    摘要:

    對三球懸鈴木（俗稱法國梧桐）落葉酸堿預處理及其同步糖化發(fā)酵產(chǎn)氫工藝進行實驗研究,，利用修正的岡珀茨模型（Gompertz model）對產(chǎn)氫曲線加以擬合,，以累積產(chǎn)氫量和產(chǎn)氫速率為考察指標，研究不同酸堿預處理方法（添加質(zhì)量分數(shù)為2%,、4%、6%,、8%的H2SO4和Ca(OH）2）對三球懸鈴木落葉光合生物產(chǎn)氫性能的影響規(guī)律,，優(yōu)化出最佳酸堿預處理工藝條件為：稀酸預處理后的落葉試樣的產(chǎn)氫性能優(yōu)于氫氧化鈣預處理后的落葉試樣，其中H2SO4質(zhì)量分數(shù)為4%時處理效果最佳,，發(fā)酵產(chǎn)氣中的氫氣最大體積分數(shù)達66.34%,，累積產(chǎn)氫量為369mL，最高產(chǎn)氫速率11.03mL/h,。稀酸處理液可以實現(xiàn)3次有效回收利用,。

    Abstract:

    This study mainly investigated the effect of acid and alkaline pretreatment on Platanus orientalis (known as the French phoenix) leaves, and also the simultaneous saccharification and photo-hydrogen production from the leaves were pretreated with acid and alkali of different concentrations. Taking cumulative hydrogen production and hydrogen production rate as assessment indicators, the photo-hydrogen production capabilities from leaves with different pretreatments were compared and the modified Gompertz equation was used to analyze hydrogen production process. The results showed that H2SO4 pretreatment could effectively improve the performance of photo-hydrogen production comparing with Ca(OH)2 pretreatment, and the 4% H2SO4 pretreatment was the best pretreatment. The maximum hydrogen concentration, the cumulative hydrogen production and the highest specific hydrogen production yield rate were 66.34%, 369mL, 11.03mL/h, respectively. The exploratory research was carried out about the dilute acid treatment liquid for recycling and reducing the cost of preprocessing.
