| 摘 要： | 以锯末粉体为生物质热解焦油研究对象,研究了热解温度对焦油产量和焦油化学成分的影响规律,结果表明,热解温度为500℃时,生物质热解产生的焦油量最大,温度过高或过低都有利于焦油的减少。不同热解温度下,焦油中碳氢化合物的成分主要是芳香烃和少量的脂肪烃,含氧化合物主要是苯酚及其烷基衍生物,含氮化合物主要是吡啶、吡咯及其烷基衍生物等杂环化合物。

| Abstract: | Sawdust was chosen as raw materials for biomass pyrolysis tar experiments.Then experiments about the influence of reaction temperature to the yield of tar and the chemical composition of tar had been studied.The results showed that the yield of tar derived from biomass pyrolysis reached maximum at 500 ℃,the higher or lower temperature were conducive to the reduction of biomass tar.Under the different temperature,the hydrocarbons of tar are mainly aromatics and a small amount of aliphatic hydrocarbons,the oxygenated compounds are mainly phenol and its alkyl derivatives,the nitrogen compounds are mainly heterocyclic compounds,such as pyridine,pyrrole and its alkyl derivatives. |
