摘要

本文的目的是研究温度对不同木质纤维素生物质厌氧消化的影响,如竹尘和锯末。将竹屑、锯末与牛粪按1:3的比例混合在容积为1000 ml的间歇式厌氧消化池中,温度分别为35℃、45℃和55℃。每隔5天,从蒸煮器中取出10毫升消化后的浆液,测试总固体和挥发性固体含量。研究了温度对反应动力学速率常数的影响。据观察,沼气产量随着温度的升高而增加。动力学速率常数是反映消化过程的重要指标。

Effect of temperature on biogas production from lignocellulosic biomasses
The objective of this paper is to investigate the effect of temperature on anaerobic digestion of different lignocellulosic biomasses such as bamboo dust and saw dust. Bamboo dust and saw dust were mixed with cattle dung in 1:3 ratio in batch type anaerobic digesters of volume 1000 ml at 35°C, 45°C and 55°C temperatures. At five day interval, 10 ml of digested slurry was taken out from the digesters and tested for total solid and volatile solid contents. Effect of temperature on kinetic rate constant was also studied. It was observed that biogas production increases with temperature. The kinetic rate constant plays a significant role to indicate the digestion process.
