| 摘 要： | 利用自行设计研制的小型生物质热裂解反应器,对桉树木屑热解产油的试验条件进行了研究。结果表明,当热裂解温度为500℃,进料速率为300 g/h时,生物油的产率达到最大,达40.3%。升温速率的增加,有助于提高生物油的产率。GC-MS分析表明,桉树木屑生物油是一种成分复杂的有机化合物的混合物,含氧量较高。其主要组分为有机酸和酮类。其中乙酸含量占50.6%,羟基丙酮占10.9%。生物油经过精制加工得到高品质的生物燃油后,结合生物质热解气、生物质炭的利用,可实现生物质综合能源化利用。

| Abstract: | The biomass pyrolysis of eucalypt sawdust was studied using a self-made bench-scale pyrolysis reactor.The results showed that the maximum bio-oil yield ratio was 40 wt% at a pyrolysis temperature of 500 ℃ and a feed rate of 300 g/h.High heating of raw materials make biomass particle pass charring zone at lower temperature more quickly to reduce char production,while improve bio-oil production.The eucalypt sawdust bio-oil analyzed by GC-MS was a mixture of complex organic compounds with extensive existence of oxygen.The bio-oil mainly contained organic acids and ketone.The content of acetic acid and hydroxyacetone were 50.6%,10.9%,respectively.Bio-oil could be refined to gain high quality bio-oil.Upgrading of bio-oil and combined with the utilization of gas and char.Biomass can be comprehensively utilized as a clean energy source. |
