摘　　要：为了拓宽生物油的应用领域,采用间歇式给料的鼓泡流化床对典型生物质(桦木屑、玉米秸秆和稻壳)的快速热解进行了试验,对生物油、柴油与稻壳油混合的乳化油进行了分析.结果表明:木屑生物油的产率最高,生物油的热值为16～18MJ/kg,其主要成分为酸类、酚类、呋喃类、醇类和烷烃类.针对生物油难于利用的特点,将生物油与柴油乳化混合,对其乳化比例和理化特性进行了研究,发现乳化油比生物油更稳定,乳化方法简单、可行.To widely utilize bio-oils as fuel,fast pyrolysis for the production of biomass oils from typical biomass feedstocks such as birch chip,corn straw and rice husk was implemented by adopting a bubbling fluidized bed with discontinuous feed,and then biomass oils and the emulsion oil mixed from bio-oil and diesel oil were analyzed.Results indicate that the bio-oil production efficiency of wood is higher than that of herbaceous species,the heating value of biomass oils is 16-18 MJ/kg.The oils are multicomponent mixtures comprising various groups of organic compounds,in which acids,phenolics,furans,alcoholic aldehydes and hydrocarbons are the main components.Considering that it is difficult to utilize bio-oils directly,the emulsion oil proportions and physical chemistry characteristics were studied for emulsion oil production.The result shows that properties of emulsion oil are more stable than those of bio-oil and diesel oil,and the emulsion method is simple and feasible.
