The objective of this work was to produce renewable liquid fuel (bio-oil) from locally produced bagasse by pyrolysis in a batch feeding and fixed bed reactor. The experiments were performed at different temperatures ranging from 300 to 600
°C. The bio-oil was collected from two condensers of different temperatures and defined as oil-1 and oil-2. The maximum total yield of bio-oil was found to be 66.0
wt% based on bagasse. The carbon based non-condensable gases were CO, CO
2, methane, ethane, ethene, propane and propene. The density and viscosity of oil-1 were found to be 1130
kg/m
3 and 19.32 centipoise and that were 1050
kg/m
3 and 4.25 centipoise for oil-2, respectively. The higher heating values (HHV) of them were 17.25 and 19.91
MJ/kg, respectively. The pH of the bio-oils was found to be around 3.5 and 4.5 for oil-1 and oil-2, respectively. The water, solid and ash contents of oil-1 and oil-2 were determined and found to be around 15, 0.02 and 0.03
wt% and 11, 0.01 and 0.02
wt%, respectively based on bagasse.
