研究了原装锥形喷动床反应器的锯末在惰性气体(N_2)中的闪速热解性能，实验范围为350−~700°C，平均气体停留时间为50ms。研究了热解温度对气产率、液产率、焦产率、气液组成及焦炭性质的影响。450℃时液体产率最高(相当于70wt%)，GC/MS测定的液体组成与文献报道的鼓泡床相似。虽然焦炭多孔结构的形成需要高于600℃的温度，但在这些条件下获得的二氧化碳产量是不可接受的。
The performance of original equipment provided with a conical spouted bed reactor has been studied in flash pyrolysis of sawdust with an inert gas (N2) in the 350−700 °C range and with 50 ms of average gas residence time. The effect of pyrolysis temperature on the yields of gas, liquid, and char on gas and liquid composition and on char properties has been studied. The maximum yield of liquid (corresponding to 70 wt %) is obtained at 450 °C and its composition determined by GC/MS is similar to that reported in the literature for bubbling fluidized beds. Although temperatures above 600 °C are required for the development of the char porous structure, the yield of CO2 obtained under these conditions is unacceptable.
