芦苇浆黑液在流化床上的热解实验研究
, PP. 1068-1075
Keywords: 芦苇浆黑液,流化床,热解,焦油
Abstract:
？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%。
