Abstract

В обзоре представлены данные, обобщающие основные направления по работе с дезактивированными катализаторами. Рассмотрено современное состояние технологий по регенерации и реактивации катализаторов гидроочистки. Кратко изложены промышленные технологии проведения окислительной регенерации катализаторов гидроочистки дизельных фракций. Освещены требования, предъявляемые к регенерированным катализаторам для проведения реактивации. Продемонстрированы реакции, протекающие в ходе регенерации и реактивации, а также условия, способствующие необратимой дезактивации.
