摘　　要：通过对植物秸秆的糖化降解,在不同时间、不同温度下测定糖含量,并进行产氢实验。结果表明,用盐酸降解植物秸秆的效果比醋酸好,在时间为1h、温度在20℃时,各有最大的糖度值36.8、35.4Brix,相对应产氢量为0.02mL、0.0182mL H_2/L糖化液。因此,利用秸秆糖化技术并进行产氢的可行性研究会成为一个研究热点。In order to alleviate the excessive exploitation of energy consumption and better protec the environment, biological hydrogen production was studied. The plant stalks of saccharificating degradation and hydrogen production have veri-fied with sugar content at different times, under different temperatures. It was showed that the effect of hydrochloric acid on the degradation of plant stalk is better than that of acetic acid, and in time for 1 h, at the temperature of 20℃, the maximum sugar degree 36.8Brix and 35.4Brix were obtained for use of hydrochloric acid and acetic acid, respectively, corresponding to hydrogen production capacity of 0.02mL H^2/L sacchariferous liquid and 0.0182mL H_2/L sacchariferous liquid. The use of straw glycosylated hydrogen production technology will become a hotspot.
