褐煤和油菜秸秆低温共热解产物及协同效应分析(英文)
发布时间:2021-06-06 09:16
印尼褐煤(IL)与不同质量分数的油菜秸秆(RS)在自制的低温煤炭化炉中共热解,得到热解半焦和焦油。结果表明:当RS的质量分数为30%时,共热解油的产率达到最大值14.03%,产率比纯褐煤热解油产率高57.59%。热解半焦的SEM结果表明,共热解半焦比褐煤半焦孔隙结构更加丰富;热解油的FTIR和GC-MS结果表明,共热解焦油更轻质化,酸度更低;样品的热重分析表明,油菜秸秆与褐煤的DTG峰值部分重叠,共热解过程符合二级动力学方程,加入RS后,共热解反应的活化能E降低,反应性增强,TG曲线向低温区域移动。RS和IL的共热解存在协同效应,共热解实现了褐煤和油菜秸秆的清洁高效利用。
