为了掌握芦苇浆黑液的热解行为,利用流化床在530、580、630、680、730和780℃六个床温下对芦苇浆黑液在氮气氛围下的热解过程进行了实验研究,分析了床温对气相产物、碳的转化率、NOx和SO2的排放浓度、焦油成分和热解焦微观形貌的影响。结果表明,热解气中的主要成分为CO、CH4、CO2和H2,床温的升高有利于H2和CO的生成,而不利于CH4和CO2的生成；可燃气体积分数随着床温的升高而升高,其值从59.2％(530℃)升高到66.1％(780℃)；床温较高时,热解产生的焦油量较少,其中,多环芳烃化合物的相对含量较多,该值在780℃时最高为46.88％。

To improve the knowledge about pyrolysis behavior of reed black liquor, pyrolysis experiments were carried out at 530, 580, 630, 680, 730 and 780 ℃ in fluidized bed under atmospheric N2 . Effects of bed temperature on yields of gas product, carbon conversion, emission of NOx and SO2 , characterization of tar, and micro-morphology of pyrolysis char were examined. The results show that the main components of gaseous product are CO, CH4 , CO2 and H2 . The volume percentage of H2 and CO increases with increasing bed temperature, but that of CH4 and CO2 is opposite. In addition, with increasing temperature the concentration of combustible gases increases from 59 . 2% at 530 ℃ to 66 . 1% at 780 ℃. The yield of tar decreases with increasing temperature. The relative content of polycyclic aromatic hydrocarbons is 46. 88% at 780℃, which is the maximum among six bed temperatures.
