摘要

以谷氨酸、甘氨酸和苯丙氨酸作为生物质的含氮模型化合物

进行化学链燃烧实验

主要考察了反应温度、氨基酸种类、碱金属钾元素等对化学链燃烧还原反应过程中氮氧化物释放特性的影响。结果显示

挥发分氮的释放迅速

温度的升高有利于NO和NO2的生成

N2O的生成会出现波动。模型化合物的氮含量越高

可能越不利于氮向氮氧化物的转化。钾元素对苯丙氨酸的化学链燃烧过程中NO的释放抑制作用较强

而对其他氨基酸化学链燃烧过程中氮氧化物释放的影响则不太显著。

Abstract

The experiment was conducted using glutamic acid

glycine and phenylalanine as N-containing model compounds. During their reduction in chemical looping combustion (CLC)

the effects of temperature and K element on NOx release were studied. The results indicated that release of volatile-N was quick during whole CLC process

and yields of NO and NO2 increased with increasing temperature

whereas N2O concentration showed fluctuation. Higher nitrogen content in model compounds

more difficult for conversion from nitrogen to NOx. K element showed no significant effect on NOx release of the three amino acids during CLC process except that NO emission from phenylalanine.
