Experiments on flash pyrolysis of biomass (rice husk and sawdust) were performed in an entrained flow reactor at different temperatures (700-1000 degrees C). Results show that temperature has great impact on the biomass flash pyrolysis reactions. With the increase of temperature, the gas yield increased, while the yields of char and liquid decreased. After the early stage of pyrolysis, the gas yield increased gradually which could be attributed to the increase of CO and CH(4) yields at low temperature, while to the increase of CO and H(2) yields at high temperature. A first order kinetic model was employed to describe biomass flash pyrolysis characteristics and the relevant kinetic parameters were determined. Numerical simulation of pyrolysis process was carried out, the predicted yields of produced gases agreed reasonably with the experimental data.
在不同温度（700-1000°C）下，在夹带流反应器中进行了生物质（稻壳和木屑）的快速热解实验。结果表明，温度对生物质快速热解反应有很大的影响。随着温度的升高，气体产率增加，而炭和液体产率降低。在热解的早期阶段，气体产率逐渐增加，这可以归因于低温下 CO 和 CH4 产率的增加，而在高温下 CO 和 H2 产率的增加。采用一级动力学模型来描述生物质快速热解的特征，并确定了相关的动力学参数。对热解过程进行了数值模拟，预测的气体产率与实验数据吻合较好。
