Abstract

Changes in composition and structure occurring in cobalt promoted and unpromoted Mo/Al2O3 catalysts during several subsequent cycles of activation and regeneration have been studied. Regeneration does not lead to the initial oxide form of the catalysts completely. The changes in the oxide catalyst composition increase with increasing number of activation-regeneration cycles.

Abstract

Исследовали изменения в строении и структуре, происходящие на нанесенных и ненанесенных катализаторах Mo/Al2O3 в ходе некоторых последовательных циклов активации и регенерации. Регенерация не приводит полностью к исходной окисной форме катализаторов. Изменения в строении окисного катализатора увеличиваются с повышаюшимся числом циклов активация-регенерация.
