Abstract

Pyridine (py) and acetic acid (Ac) adsorption on dealuminated HY zeolites with Al content in the range of 3.9–58 per unit cell (U.C.) was studied at 553 K by a flow-gravimetric technique. The ratio of the number of adsorbed py and Ac molecules to the number of Al atoms was plotted as a function of the Al content. The plot passes through a maximum for py and a minimum for Ac. The extrema are at about 30 Al/U.C.

Abstract

Адсорбцию пиридина (Py) и уксусной кислоты (Ac) на деалюминированных цеолитах HY с содержанием Al 3,9–58 на единицу ячейки (U.C.) исследовали при 553 к с помощью струевого гравиметрического метода. Отношение числа адсорбированных молекул Py и Ac к числу атомов Al изображали в зависимости от содержания Al. Кривая имеет максимум в случае Py и минимум в случае Ac. Экстремы находятся в области 30 Al/U.C..
