Pyrolysis of treated/untreated bagasse: The effect of heating method and extra washing on bulk and chemical component yields

In this study, catalytic/non-catalytic pyrolysis of pretreated/untreated bagasse was performed under vacuum in a fixed bed reactor. For finding the best heating method two ways were used. In the first way, the temperature of feedstock raised from ambient temperature to 400 °C with a heating rate of 12 °C min-1 and in the second way, the temperature was set to 400 °C and then the reactor was put in the furnace. The second method was favored for bio-oil production with higher yields and less oxygenated compounds. Also, pyrolysis experiment was performed after pretreating bagasse with concentrated HCl. Pretreatment caused to the reduction in bio-oil production. By the extra washing of pretreated bagasse with water, the bio-oil yield slightly improved.
