焦油对生物质气化再燃还原no的影响
Keywords: 生物质,气化,焦油,氮氧化物,效率
Abstract:
采用配制含焦油模型化合物的生物质气的方法,实验研究了焦油的加入对生物质气化再燃还原no的影响.模拟的生物质气化气由h2、ch4、co、co2、n2构成,并选择了苯、甲苯、苯酚和苯乙烯作为焦油模型化合物.实验在电加热的刚玉管流反应器中进行,实验温度在900~1,400,℃之间.研究了反应器入口焦油含量、氧气浓度、no初始浓度、反应停留时间及反应温度等因素对还原no的影响,分析了含焦油的生物质气化再燃特性.证实了焦油有助于提高生物质气化气还原no的效率;含焦油的生物质气化再燃的最佳当量比在1.20~1.65之间,并且随着no初始浓度的增加及停留时间的延长,no还原效率逐渐增加;高温下,焦油含量较高时,有炭黑生成.
