Abstract

The content of non-stoichiometric oxygen in Cr2O3 catalysts of different dispersity has been determined by a direct thermodesorption method. A sharp decrease in the content of non-stoichiometric oxygen after calcination of the samples above 500°C was observed.

Abstract

Прямым термодесорбционным методом определено содержание сверхстехиометрического кислорода Cr2O3 катализаторов разной дисперсности. Установлено резкое уменьшение сверхстехиометрического кислорода после прокаливания при температурах выше 500°C.
