【摘要】 在中国,废弃菌糠的产量以每年8百万吨的速度持续增加【1】。但不幸的是,其中大部分往往被焚烧或作为有机废物进行自然分解,这不仅造成了资源浪费,也给环境带来了严重的危害【2】。目前,我们的工作聚焦在白灵菇菌糠的热解性质及其液化产物的分析上,通过热重分析技术,白灵菇菌糠的动力学参数被计算获得,不同升温速率对其热解过程的影响也被确定。此外,干馏热解实验数据显示,最佳的热解温度出现在470℃,对应的生物油产率为14.4wt.%。通过对白灵菇菌糠液化产品的元素分析,碳氢比暗示其位于轻质和重质油品之间。红外和气质联用分析显示获得的生物油中含有较多的有机组分,主要以酚类、烃类为主。以上这些结果表明,获得的生物油经过升级之后,能够作为一种潜在能源去被利用。更多还原

【Abstract】 In China, the growth rate of spent mushroom substrate is more than 8 million tons per annum [1]. Unfortunately, residues tend to be incinerated or dumped as organic wasters to decompose naturally. These result in wasting of resources and bring negative impact on the environment [2]. To date, our study is mainly focused on the pyrolysis behavior of spent lark mushroom substrate and the characterization of obtained production. Kinetic parameters are calculated and the role of heating rates on pyrolysis process is determined by TGA. Otherwise, the optimum pyrolysis temperature is found at 470℃ with the yield of 14.4 wt.%. The H/C ratio indicates the obtained bio-oil lie between those of light and heavy petroleum products. The FT-IR and GC-MS shows it consists of phenols, hydrocarbons and other components. Above-mentioned results show that after upgrading, the obtained oil can be used as potential energy resource.更多还原
