摘  要:
以笋壳为原料,石英砂为流化介质,在自行研制的流化床快速热解装置上进行热解试验,研究了热解温度、物料尺寸、进料速率、滞留时间和添加剂对笋壳热解产物分布的影响。结果表明:加入添加剂KNO3热解效果较好,较佳工艺条件是热解温度500℃、物料尺寸1.0 mm、进料速度50 g.min-1、滞留时间0.8 s、KNO3浓度0.4%,液体产率可达62.7%。

摘  要:
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%.
