Структура и каталитические свойства нанесенных оксидномолибденовых, оксиднованадиевых и оксиднохромовых катализаторов дегидрирования углеводородов. 19. Фазовый состав, текстура и структура поверхности окисленных алюмохромовых катализаторов

Abstract

A brief review of literature works on the phase composition, texture and oxidized surface structure of impregnated chromia-alumina catalysts is presented. The valence states of chromium ions in the oxidized chromia-alumina catalysts, chromium oxide redispersion processes on Al2O3 surface and chromia effects on the phase composition and texture of alumina support in Cr2O3/Al2O3 samples during their thermal treatments in air are considered.

Представлен краткий литературный обзор работ по фазовому составу, текстуре и структуре окисленной поверхности пропиточных алюмохромовых катализаторов. Рассмотрены валентные состояния ионов хрома в окисленных алюмохромовых катализаторах, процессы редиспергирования оксида хрома на поверхности Al2O3 и влияние Cr2O5 на фазовый состав и текстуру алюмооксидного носителя в Cr2O3/Al2O3-образцах при их термической обработке на воздухе.
