The characteristics and mechanism of NO formation during pyridine oxidation in O-2/N-2 and O-2/CO2 atmospheres
The characteristics and mechanism of NO formation during pyridine oxidation in O-2/CO2 atmospheres are investigated both experimentally and numerically. Comparison experiments in O-2/N-2 and O-2/CO2 atmospheres are performed in a flow reactor at atmospheric pressure covering fuel-rich to fuel-lean equivalence ratios with temperature ranging from 773 K to 1573 K. Experimental results indicated that HCN is completely consumed in CO2 atmospheres, whereas significant amounts remain in N-2 atmospheres under fuel-rich conditions. Compared with O-2/N-2 atmospheres, the formation of NO in O-2/CO2 atmospheres is reduced by 8.85% and 5.8% under stoichiometric and fuel-lean conditions respectively, whereas it is 5.15% greater under fuel-rich conditions. A newly developed chemical kinetic mechanism based on our previous studies satisfactorily reproduced the main features of CO, HCN, and NO formation. The conversion differences of pyridine to NO between O-2/CO2 and O-2/N-2 atmospheres are mainly due to the differences of conversion of HCN to NO. The conversion ratio discrepancies of pyridine to HCN are all less than 2%. The conversion ratios of HCN to NO in O-2/N-2 and O-2/CO2 atmospheres are 7.2% and 15.6% under fuel-rich conditions, 65.3% and 57.4% under stoichiometric conditions, and 83.5% and 76.3% under fuel-lean conditions, respectively.
