This paper presents data on methane fermentation of algal biomass containing Chlorella sp. and Scenedesmus sp. The biomass was obtained from closed-culture photobioreactors. Before the process, the algae were subjected to low temperature and pressure pretreatment for 0.0, 0.5, 1.0 and 2.0 h. The prepared biomass was subjected to mesophilic methane fermentation. The amount and composition of the biogas formed in the process were determined. The amount of biogas produced was larger when the biomass was subjected to thermal preprocessing. The proportion of methane in the gas also increased. Extending the heating time beyond 1.0 h did not significantly improve the biogassing effects.
本文展示了含有小球藻属和栅藻属的藻类生物质进行甲烷发酵的数据。该生物质取自封闭式培养光生物反应器。在该过程之前，藻类进行了0.0、0.5、1.0和2.0小时的低温和压力预处理。制备好的生物质进行了中温甲烷发酵。测定了该过程中形成的沼气的量和组成。当生物质进行热预处理时，产生的沼气量更大。气体中甲烷的比例也增加了。加热时间延长超过1.0小时并没有显著改善沼气产生效果。
