利用GC-MS分析生物质与煤共热解油组成

Analysis the Composition of the Co-pyrolysis Oil by Biomass and Coal by GC-MS

文章主要利用GC-MS对生物质与煤快速共热解油品组成进行分析。结果表明:共热解油品组成复杂,已检测到的物质可分为脂肪类、芳烃类、酚类及其他含O、N、S等杂原子类物质,其中芳烃类占主要组成,含量高于60%。就定量分析结果而言,共热解焦油与煤单独热解焦油组成相近,可通过进一步的加工制取优质燃料油及化工产品。

In the paper, focus on the study of the composition of the oils from biomass and coal flash co-pyrolisis by Gas Chromatograph-Mass Spectrometer. The results have shown that the detected compounds consisted of aliphatic hydrocarbons, aromatics, phenols and other oxygen-obtained/nitrogen-obtained /sulfur-obtained materials, and the content of aromatics accounted more than 60 %. As for the quantitative analysis result, the co-pyrolysis tar has the similar compositions with the tar by coal pyrolysis, which in further can be processed for high quality fuel oil and chemical products.
