Abstract

To convert unutilized plant biomass into a useful energy source, methane production from bamboo was investigated using a steam explosion pretreatment. Methane could not be produced from raw bamboo but methane production was enhanced by steam explosion. The maximum amount of methane produced, i.e., about 215 ml, was obtained from 1 g of exploded bamboo at a steam pressure of 3.53 MPa and a steaming time of 5 min. A negative correlation between the amount of methane produced and the amount of Klason lignin was observed in the methane fermentation of steam-exploded bamboo.

摘要

为了将未利用的植物生物质转化为有用的能源，采用蒸汽爆破预处理对竹子产甲烷进行了研究。未经处理的竹子不能产生甲烷，但蒸汽爆破可提高甲烷产量。在蒸汽压力为3.53 MPa、蒸煮时间为5分钟的条件下，1克经爆破处理的竹子产生的甲烷量最多，约为215毫升。在蒸汽爆破竹子的甲烷发酵过程中，观察到甲烷产量与克拉森木质素含量之间呈负相关。
