Abstract

The influence of the temperature of calcination of Ni, Fe oxide catalysts on some of their physico-chemical and catalytic properties was investigated. The catalytic test reactions were the decomposition of isopropyl alcohol and the cracking of cumene. The phase boundary surfaces of the NiO−Fe2O3−NiFe2O4 system seem to be the main source of the catalytic activity of these oxides.

Abstract

Было исследовано влияние температуры кальцинирования окислов Ni и Fe на их физико-химнческие и каталитические свойства. Проба каталитического действия была исследована на разложении изопропилового спирта и крекинге кумена. Источники каталитической активности этих окислов находятся на поверхности раздела системы NiO−Fe2O3−NiFe2O4.
