摘要
生物质经快速热解制备的生物油是一种清洁的可再生能源产品.为此,利用气相色谱质谱联用仪分析了生物油的组分性质,采用填料式精馏塔对生物油进行实沸点(true boiling point,TBP)蒸馏实验,实验分别在常压环境(0.1,MPa)及减压环境(0.01,MPa)下进行,得到了生物油的3个宽馏分.结果表明:在常压环境下,汽油馏分的收率为19.2%,柴油馏分的收率为26.4%;在减压环境下,汽油馏分收率为30.5%,柴油馏分收率为23.3%.在实验的基础上,本文利用Aspen Plus软件建立了生物油实沸点蒸馏的模拟流程,并计算得到了生物油的恩氏蒸馏曲线.
Bio-oil produced via biomass fast pyrolysis process is a clean and renewable energy product. Bio-oil components were analyzed by GC-MS. The true boiling point(TBP)distillation experiments of bio-oil were carried out at atmosphere pressure(0.1,MPa)and reduced pressure(0.01,MPa)in the filled distillation column to obtain three fractions. The results show that the yield of gasoline fraction is 19.2% at atmosphere pressure and 30.5% at reduced pressure,in comparison with yield of diesel fraction of 26.4% and 23.3%,respectively. Finally,a bio-oil TBP distillation simulation model was set up with Aspen Plus and the Engler distillation curve of the bio-oil was obtained.
