摘　　要：进行高含氮木质废弃物的加压气化试验,研究反应压强对于气化的影响。结果表明:在高压热重上,高压可抑制挥发分析出,提高700℃以上气化反应速度,使气化结束温度从1104降至1076℃;在加压气流床装置上,增大压强可明显提高合成气的品质,CO与H_(2)浓度明显增大,气化碳转化率、产气率与低位热值均有提高;随着压强的增大,高含氮木质废弃物气化产气中HCN与NH3浓度出现下降趋势,从4606和2405 mg/m^(3)分别降至393和622 mg/m^(3)。In this paper,the pressurized gasification of nitrogen-rich wood waste was carried out on a pressurized thermogravimetric,and the effects of reaction pressure were studied on gasification products and processes.The experimental results showed that the high pressure on the pressurized thermogravimetric inhibited the precipitation of volatiles,but increased the reaction rate in the gasification stage above 700℃,and reduced the end temperature of gasification from 1104℃at atmospheric pressure to 1076℃at 1 MPa pressure.In the pressurized entrained-flow bed,the increasing of gasification pressure could significantly improve the quality of syngas,and the concentrations of CO,H2 increased individually.Besides,the carbon conversion,gas yield and low calorific value all increased obviously.With the increase of gasification pressure,the concentrations of HCN and NH3 of the gaseous products gasification from nitrogen-rich wood waste decreased rapidly from 4606 and 2405 mg/m^(3) to 393 and 622 mg/m^(3) respectively.
