落叶松树皮喷动循环流化床快速热解的影响因素

摘要

对喷动循环流化床落叶松树皮快速热解过程中反应温度、物料粒径、进料速率及气体流量对热解产物产率的影响以及这4个因素共同作用对生物油产率的影响进行研究.结果表明:反应温度是影响热解产物产率的主要因素,气体流量影响较显著,在试验范围内物料粒径、进料速率影响不显著;喷动循环流化床最佳制备液体产物--生物油快速热解工艺条件为:反应温度550℃,物料粒径0.2～0.3 mm,进料速率20r·min~(-1),气体流量25m~3·h~(-1).%An experimental studied on the influence of larch bark fast pyrolysis in spouting-circulating fluidized bed products yield, in the pyrolysis process of reaction temperature, gas flow, particle size and feed rate, and the effects of the four factors in the interaction of bio-oil yield. The results show that: reaction temperature is the main factor that influences of pyrolysis yield of products, gas flow shows obvious influence, particle size and feed rate have no significant influence; spouting-circulating fluidized bed pyrolysis optimum conditions: reaction temperature 550℃ .particle size 0.2 ~ 0.3 mm,feed rate 20rmin-1,gas flow 25 m~3·h~-1).
