摘要:利用热重-傅里叶变换红外分析仪(TG-FTIR)和管式炉装置等技术,对木质素与豆粉和尼龙共热解及燃烧过程中有机氮释放规律进行了研究,分析了各温度下的协同效应。结果表明,热解工况下,豆粉和尼龙材料热解主要生成NH3。当豆粉与木质素质量比达到1:1时,NH3增加15.6%,但HCN降低了73.1%;对尼龙,加入同样比例的木质素可有效降低18.5%的NH3。燃烧工况下,当豆粉与木质素质量比为3:1时,NOx排放量仅为计算值的28.1%;木质素也使尼龙减排36.6%的NH3。木质素对2种材料的作用机理不同,但都能有效降低热转化过程中含氮气体的排放。

Abstract:The organic nitrogen release property during co-pyrolysis and combustion of soybean powder and nylon with lignin were experimentally investigated by TG-FTIR and tubular furnace reactor, and the synergistic effects at different temperatures were discussed. The results indicate that NH3 is the primary N-containing gas during the pyrolysis of soya powder and nylon. When soya was co-pyrolyzed with lignin at a rate of 1:1, NH3 concentration increased by 15.6%, while HCN concentration decreased by 73.1%. For co-pyrolyzing nylon with lignin at the same rate, NH3 concentration decreases by 18.5%. When soya was co-combusted with lignin at a rate of 3:1, the NOx emission can be reduced to 28.1% of the calculated value. When nylon was co-combusted with lignin, NH3 concentration was reduced by 36.6%. It suggested the synergetic effect of lignin could inhibit the organic nitrogen release during the thermochemical treatment of soya powder and nylon with different reaction mechanism.
