Abstract

Catalytic properties of a series of HfO2−Eu2O3 fine crystalline powders were examined by the isomerization of n-butenes. HfO2 pretreated at 873 K showed a high activity. It decreased with the addition of the Eu component. The product distributions are discussed on the basis of the acid-base properties.

Abstract

Каталитические свойства ряда тонкокристаллических порошков HfO2−Eu2O3 исследовали в изомеризации н-бутенов. HfO2, подверженный предварительной обработке при 873 K, обладает высокой активностью. Последняя уменьшается с добавкой Eu. Распределение продуктов обсуждается на основе кисло-основных свойств.
