Vf. Tret'Yakov et al., Selective NO reduction by propane over commercial oxide catalysts and their mechanical mixture: I. Synergistic effect, KINET CATAL, 41(2), 2000, pp. 236-241
In the reaction of NO reduction by propane in excess oxygen, the activity o
f a binary mixture of commercial oxide catalysts is higher than should be e
xpected if it were proportional to the activities of separate catalyst comp
onents. This synergism reveals itself in the fact that the conversion of NO
and C3H8 is higher when the catalyst is a mechanical mixture than the sum
of conversions over separate catalysts, all other conditions being the same
. Based on the kinetic and thermal desorption measurements, the experimenta
l conditions are found under which the synergism is observed. A hypothetica
l mechanism is proposed.
