Реферат: Transient response experiments indicated that H2-promoted n-C6H14-SCR over Ag/Al2O3 has a significant contribution from the pathway proceeding through the formation of surface nitrate complexes (NO3 −)surf followed by their reduction. The rate of (NO3 −)surf reduction by 300 ppm C6H14 in the presence of 1,000 ppm H2 is virtually identical to the rate of steady-state H2-promoted n-C6H14-SCR, while surface nitrate species reveal their inertness with respect to 300 ppm n-C6H14 only. Transient response experiments and temperature programmed desorption indicate that (NO3 −)surf is readily transformed by NO or H2 to the reactive (NO2 −)surf complexes. The latter are further reduced by n-hexane in the presence of H2.
