Abstract

Настоящее изобретение относится к способу получения носителя -AlOи включает а) смешивание источника алюминия с добавками и связующим веществом; б) экструдирование замешанной пасты в цилиндрическую полосу; в) гранулирование цилиндрической полосы и дальнейшее округление гранул с получением шариков; г) сушку и прокаливание шариков с получением готовых шариков -оксида алюминия, где вышеупомянутый источник алюминия включает в себя диаспор, псевдобемит и любой гиббсит. Настоящее изобретение также относится к носителю -AlO, полученному описанным выше способом, и к применению данного носителя. По сравнению с носителем -AlOпредшествующего уровня техники, носитель -AlO, полученный по настоящему изобретению, может не только повысить общую прочность катализатора, но и полученный палладиевый катализатор обладает такой же или даже более высокой активностью и селективностью по сравнению с катализаторами предшествующего уровня техники.
