At 500[degrees]C, the yields of bio-oil, char and non-condensable gas were 66.70wt%, 22.60wt% and 10.70wt%, 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 1.11g/mL and 2.34cP, respectively. The lower heating value (LHV) of bio-oil was found to be 18.25MJ/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 135mg KOH/g, respectively. The water, lignin, solid and ash contents of bio-oil were determined and found to be around 15wt%, 4.90wt%, 0.02wt% and 0.10wt%, respectively.
