Abstract: Pyrolysis experiments on the bamboo shoot shell were carried out in a custom-designed fluidized bed.The bed applied quartz sand as the fluidizing medium.The effects of temperature,material size,feeding rate,retention time and additives on bio-oil yield were studied.The results showed that the optimal pyrolyis conditions included 0.4% addition of KNO3,temperature at 500℃,material size of 1.0 mm,feeding speed at 50 g/min and retention time of 1s.Under such conditions,the bio-oil yield reached 62.7%.
