【摘要】 设计了间歇式给料的鼓泡流化床反应器,对生物质在不同的反应温度、不同的流化气速以及不同的床层高度等条件下的生物质热解进行了研究。结果表明热解温度是生物质产油率的主要影响因素,流化气流速和床层高度对产油率也有一定的影响。在最佳的反应条件下,生物质油的产率可达65%,其主要组分为有机酸和呋喃。更多还原

【Abstract】 A bubbling fluidized bed with discontinuous feed is designed,and the experiments using sawdust as feed has been carried out to study the effects of operating parameters(temperature,rate of gas flow and bed depth) on the biomass pyrolytic behaviors.The results show that the main effect on the oil production rate is the pyrolytic temperature.But gas flow rate and bed depth can also affect the rate of bio-oil.The yield of bio-oil can be as high as 65% under optimal conditions of reactor,and the oil mainly contains organic acids and furan.更多还原
