【摘要】：为了研究紫花苜蓿酶解液作为光合制氢原料时的最佳产氢工艺条件,对产氢影响较为显著的温度、光照强度、初始pH值三种因素设计了三因素三水平L9(33)正交实验,并对实验结果进行直观分析与方差分析,以获取最佳产氢工艺条件。实验结果表明:在所选水平范围内,各因素对能源草产氢的影响主次顺序为温度→光照强度→初始pH值;由方差分析可知,温度和光照强度对能源草光合产氢性能影响为显著;初始pH值为不显著;由各因素水平值的均值可见,能源草光合生物制氢的最佳工艺水平为30℃、pH=7、光照度为3 000 lx。
[Abstract]:In order to study the optimum conditions of hydrogen production from alfalfa enzymatic hydrolysis solution as raw material for hydrogen production, three factors, namely temperature, light intensity and initial pH value, which have significant effects on hydrogen production, were designed in this paper. Visual analysis and variance analysis of the experimental results were carried out to obtain the best conditions for hydrogen production. The experimental results showed that in the selected level range, the influence of various factors on hydrogen production of energy grass was in the order of temperature. 鈫扡ight intensity. 鈫扵he effect of temperature and light intensity on photosynthetic hydrogen production of energy grass was significant, initial pH value was not significant. The optimum technological level for hydrogen production by photosynthetic organisms was 30 鈩，
