项目摘要
Nitrogen oxide reduction with carbon has been studied as a possible way to eliminate this pollutant involved in the ozone layr depletion, acidic rain falls and global warming. In order to obtain the fundamental reaction pathways occurring in the fluidized bed reactor, we have studied the reaction mechanism between carbon and NO_x and N_2O.The principal technique used was the step response experiments using isotope gases. For example, by switching the reactant gas from ^<15>N^<18>O to ^<14>N^<16>O,we can speculate the behavior of surface ^<15>N species or surfhce ^<18>O species during the reaction with ^<14>N^<16>O.From these experiments, it was clearly concluded that the main N_2 formation during C-NO reaction is the reaction between C (N) and NO.By using a similar technique, we also clarified the reaction mechanism between carbon and N_2O.During the reaction of carbon with a mixture of ^<14>N2^<16>O and ^<15>N_2^<16>O,no formation of ^<14>N^<15>N was observed, suggesting the splitting of N_2 from N_2O without N-N bond breakage.The simulation of these reactions were also studied by using molecular orbital calculation, and we found that the above mechanisms are quite reasonable.
已经研究了用碳减少氮的氮氧化物,以消除与臭氧Layr耗竭,酸性降雨和全球变暖有关的这种污染物的可能方法。为了获得流化床反应器中发生的基本反应途径,我们研究了碳和NO_X和N_2O之间的反应机制。所使用的主要技术是使用同位素气体的步骤响应实验。 For example, by switching the reactant gas from ^<15>N^<18>O to ^<14>N^<16>O,we can speculate the behavior of surface ^<15>N species or surfhce ^<18>O species during the reaction with ^<14>N^<16>O.From these experiments, it was clearly concluded that the main N_2 formation during C-NO reaction is the reaction between C (N) and NO.By using a similar technique, we also澄清了碳和n_2o之间的反应机制,以 ^<14> n2 ^<16> o和 ^<15> n_2 ^<16> o的混合物的反应,未观察到 ^<14> n ^<15> n的形成,表明使用N_2O的n_2o smotion car car cartie countions car section n n _2 car s cartie。上述机制是相当合理的。
