摘要
化石能源的储量减少与污染使人们必须寻找其他替代能源,其中生物质能是一个很好的替代品。该文以榆木木屑、红松木屑和秸秆为原料,在自制的小型流化床上开展了生物质热裂解生物油的实验研究。结果表明红松木屑的产油率最高,热裂解的温度对产油率的影响很大,500℃时生物油的产量最高,热裂解温度越高,裂解气体产量越高,气体热值也越高,而碳的产量越低。而且随着反应时间的变化,裂解气体成分也发生变化,在裂解10min左右,裂解气体中可燃气体成分最高。
Biomass energy was one kind of substituent energy due to the decrease of fossil fuel and its pollution. The effects of factors on biomass pyrolysis were investigated using wood sawdust and straw as biomass materials by a self-manufactured fluidized bed reactor. Results showed that the highest bio-oil yield was obtained at 500℃ with pine wood sawdust as biomass material. The effect of pyrolysis temperature on yield of bio-oil was big. When pyrolysis temperature was increased, the yield of pyrolysis gas as well as its heating value was increased, and the yield of char was decreased. Pyrolysis gas component varied with reaction time, the rate of flammable gas in pyrolysis gas was the highest at about 10 min.
