Abstract
Incineration is one of the mainstream techniques for the treatment of municipal waste. As the main component of municipal waste, kitchen waste incineration releases a large amount of NOx pollutants. Pyrolysis is the initial stage of incineration, during which nitrogen species in kitchen waste are converted into NOx precursors. In this study, nitrogen migration mechanism of NOx precursors (i.e., HNCO, HCN, and NH3) during the pyrolysis of 2-pyrrolidone, a typical lactam compound in kitchen waste, was investigated based on density functional theory calculations. Various formation pathways of HNCO, HCN and NH3 were discovered respectively. Meanwhile, the pathways of HNCO decomposition to HCN and NH3 at high temperature were illustrated. The formation and decomposition pathway of HCNO satisfactorily interpreted the experimental finding in which HNCO release curve decreased with the temperature rise. Furthermore, the reason for the high yield of HCN as the main product throughout the experimental temperature range and its insensitivity to temperature variation was also identified theoretically in this study.
