麦草碱法黑液热解的产物特性及释放规律
DOI: 10.3969/j.issn.1000-2006.2013.04.023, PP. 121-126
Keywords: 麦草黑液,热解,产物特性,释放规律
Abstract:
对麦草碱法制浆黑液固形物(bls)400～800℃热解产物组成特性进行了研究。采用气相色谱(gc)和气相色谱-质谱(gc-ms)对热解气相产物和液相产物组成进行了全面分析;利用扫描电镜能谱仪(sem-eds)对固相产物的表面形貌及元素分布进行了表征。借助热重红外联用技术(tg-ftir)探讨了热解过程中主要产物的释放规律。结果表明,bls热解产物中,气相产物主要成分为h2、co、co2以及cxhy(ch4、c2h2、c2h4、c2h6)等,液相产物中主要是酚类、酮类、醇类、醚类、酸类、呋喃以及芳香化合物。tg-ftir结果显示,bls热解产物释放时间主要集中在1000～2000s(300～600℃),此时bls释放的产物主要为h2o、co2、ch4、co,以及烷烃类、芳烃类、酚醇类和酮类化合物。
