摘要
在配备40 kg/h流化床反应器的半中试热解装置上，以象草为原料进行快速热解制备生物油。温度在480到520摄氏度之间变化。生物量(水分为10%)以20 ~ 35 kg/h的速度饲喂。大约4.5 kg的沙子被用作流化剂。对裂解油进行了碳、氢、氮、硫含量分析。还测定了含水量、酸度、pH值、40℃粘度、密度和高热值。色谱分析表明，其主要成分为乙酸、丁香醇、乙烯基酚、愈创木酚和己酸。用主要结果比较了不同结构的气洗塔和蒸汽冷凝系统对生物油性能的影响。Sousa et al.;学报，14(2):1-10,2016;文章no.ACSJ。25843 2
Characteristics of Bio-oil from the Fast Pyrolysis of Elephant Grass (Pennisetum purpureum Schumach) in a Fluidized Bed Reactor
Bio-oil was obtained from the fast pyrolysis of elephant grass in a semi-pilot scale pyrolysis plant equipped with a 40 kg/h fluidized bed reactor. The temperature varied between 480 and 520°C. The biomass (moisture of 10%) was fed with a rate between 20 and 35 kg/h. Approximately 4.5 kg of sand was used as fluidizing agent. The pyrolytic oil was analyzed for the contents of carbon, hydrogen and nitrogen and sulfur. Water content, acidity, pH, viscosity at 40°C, density and higher heating value were also determined. Chromatographic analysis showed that it was composed mostly of acetic acid, syringol, vinyl-phenol, guaiacol and hexanoic acid. Main results are used to compare the influence of different configurations of a gas-washing column and vapor condensation system on the properties of the bio-oil.
