Pyrolysis of jute stick for bio-oil production has been investigated in a continuous feeding fluidized bed reactor at different temperatures ranging from 300 degrees C to 600 degrees C. At 500 degrees C, the yields of bio-oil, char and non-condensable gas were 66.70 wt%, 22.60 wt% and 10.70 wt%, respectively based on jute stick. The carbon based non-condensable gas was the mixture of carbon monoxide, carbon dioxide, methane, ethane, ethene, propane and propene. The density and viscosity of bio-oil were found to be 1.11 g/mL and 2.34 cP, respectively. The lower heating value (LHV) of bio-oil was found to be 18.2 5 MJ/kg. Since bio-oil contains some organic acids such as formic acid, acetic acid, etc., the pH and acid value of the bio-oil were found to be around 4 and 135 mg KOH/g, respectively. The water, lignin, solid and ash contents of bio-oil were determined and found to be around 15 wt%, 4.90 wt%, 0.02 wt% and 0.10 wt%, respectively.
在连续进料流化床反应器中，研究了黄麻杆热解制取生物油的过程，热解温度范围为300℃至600℃。在500℃时，基于黄麻杆，生物油、焦炭和不可冷凝气体的产率分别为66.70 wt%、22.60 wt%和10.70 wt%。碳基不可冷凝气体是一氧化碳、二氧化碳、甲烷、乙烷、乙烯、丙烷和丙烯的混合物。发现生物油的密度和粘度分别为1.11 g/mL和2.34 cP。生物油的低位发热量（LHV）为18.25 MJ/kg。由于生物油含有一些有机酸，如甲酸、乙酸等，发现生物油的pH值约为4，酸值约为135 mg KOH/g。测定了生物油中的水分、木质素、固体和灰分含量，分别约为15 wt%、4.90 wt%、0.02 wt%和0.10 wt%。
