Abstract

The kinetics of low-temperature oxidation of ammonia on chromium carbide has been studied. The reaction mechanism on the carbide is similar to that on oxides and metals. The specific activity of the transition metal carbides decreases in the sequence: Mo2C>VC>Cr7C3>WC>TiC>ZrC>TaC>HfC. The selectivity to N2O generally changes in the same direction. A correlation between the activity and selectivity, and the oxygen-carbide bond energy has been found.

Abstract

Исследована кинетика низкотемпературного окисления аммиака на карбиде хрома. Механизм реакции аналогичен механизму окисления NH3 на окислах и металлах. Удельная каталитическая активность карбидов переходных металлов уменьшается в ряду: MO2C>VC>Cr7C3>WC>TiC>ZrC>TaC>NBC>HfC. Селективность по N2O изменяется, в общем, симбатно активности. Установлена корреляция активности и селективности с энергией связи кислород-карбид.
