Figures

Grahic Jump Location
Calculated concentrations of OH (top), HO2 (middle), and H (bottom) at the same conditions as shown in Fig. 1
Grahic Jump Location
Calculated composition profiles in a constant temperature (600°C) and pressure (1 atm) PFR. Initial gas composition=75 percent N2, 10 percent O2, 10 percent H2O, 5 percent CO2, 50 ppmv CO, and either 25 ppmv NO (solid lines, ———) or 0 ppmv NO (dashed line, – – –).
Grahic Jump Location
Calculated PFR composition profiles of important radical species at the conditions of Fig. 3
Grahic Jump Location
Peak rates of NO2 formation in a constant temperature and pressure PFR at various conditions. Initial gas composition=75 percent N2, 10 percent O2, 10 percent H2O, 5 percent CO2, and 25 ppmv NO. Solid line (———): initial CO concentration=50 ppmv, P=1 atm. Dotted line (⋯): initial CO concentration=12.5 ppmv, P=1 atm. Dot-dashed line (–⋅–⋅): initial CO concentration=12.5 ppmv, P=10 atm.
Grahic Jump Location
Calculated concentrations of CO (top), NO (middle) and NO2 (bottom) in constant pressure (P=1 atm) perfectly stirred reactors (PSRs) at various temperatures. Inlet gas composition=75 percent N2, 10 percent O2, 10 percent H2O, 5 percent CO2, 50 ppmv CO, and either 25 ppmv NO (solid lines and symbols) or 0 ppmv NO (dashed line). Solid and dashed lines indicate calculations using the Miller and Bowman reaction set. Symbols are points calculated using the reaction set in Table 1 (▪), Glarborg et al (•), or GRI-Mech 2.11 (▴).
