摘要
考察了葡萄糖、pH值、煤用量、Fe2+浓度交互作用下煤发酵产氢的最优培养条件.在Fe2+和pH值及葡萄糖单因素实验的基础上,应用极差分析原理,设计四因素交互作用实验.以葡萄糖、pH值、煤用量和Fe2+为响应因子,以产气量为响应值,采用响应面法处理实验数据.结果表明,在所选的因素水平范围内,葡萄糖和pH值对产气量影响显著,pH值和Fe2+之间交互作用显著,煤用量大小影响不太明显.实验证明,培养基中葡萄糖用量为6g/L,初始pH值为5.5,煤基质用量为50g/L,FeCl2·4H2O用量为10mg/L时,产氢效果最好,产氢率达24.26mL/g,为大规模工业化实验提供参考.
This paper intends to study the optimum culture condition of coal fermenting to produce hydrogen when interacted under the conditions of glucose,pH,dosage of coal and concentration of Fe^2＋.Based on the testing of which Fe^2＋,pH and glucose were used as single factors,by means of range analysis principle,a four-factor interactional experiment was designed and the data was collected by response surface method,in which glucose,pH,dosage of coal and concentration of Fe^2＋were the response factors and gas production was the response value.The results show that glucose and pH both have a notable impact on hydrogen production respectively,and the interaction between pH and Fe^2＋works significantly as well,whereas the effect of dosage of coal is not very obvious.The experiment bears out that under the conditions that the dosage of glucose is 6g/L and the original pH is 5.5,and the dosage of coal matrix is 50g/L and FeCl2·4H2O is 10mg/L,the hydrogen production effect is best and up to 24.26mL/g,which provides an advantageous reference for the large-scale industrialized experiment.
