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20 r·min-1,气体流量25 m3·h-1

Abstract:

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 20 r·min-1,gas flow 25 m3·h-1.

Key words: bio-oil, spouting-circulating fluidized bed, fast pyrolysis, influence factor
