    摘要:

    以花生殼為原料在流化床反應(yīng)器內(nèi)進(jìn)行了快速熱解實(shí)驗(yàn),。對花生殼的熱解過程進(jìn)行了物料衡算,。通過在冷凝器后增加電捕焦油器,，考察了熱解油收集方式對熱解油產(chǎn)率的影響，熱解油的收率由40%增加到64%,，說明電捕焦油器的使用不僅避免了產(chǎn)品熱解油的流失,，而且凈化了熱解燃?xì)狻Ｓ秒娔鼙韺峤膺^程的能耗進(jìn)行了計(jì)量,，計(jì)算得出花生殼熱解耗能在2304 kJ/kg左右,。通過對熱解油元素分析和物理性質(zhì)表征,分析了各級熱解油的特征及應(yīng)用。

    Abstract:

    Experimental researches on fast pyrolysis of peanut shell were performed in a self-manufactured bench-scale fluidized bed reactor at 500℃. Mass balance of pyrolysis reaction was carried out. Influence of collecting ways on bio-oil yield was investigated. Results showed that bio-oil yield raised from 40% to 64% after the electrostatic precipitators （ESP）settled at the end part of the fractional condensers which prevented bio-oil from losing together with produced gas and cleaned the produced gas. Energy consumption of peanut shell pyrolysis was monitored at about 2304kJ/kg with a watt-hour meter. The physical properties and application of bio-oil were discussed by means of analysis instruments.
