Abstract

The conversions of 1-methylnaphthalene on NaY zeolite and its magnesium modifications with different degrees of ion exchange and various Si/Al ratios have been studied at 310 and 350 °C. The investigated catalysts are highly active for positional isomerization. The observed changes in their catalytic activity are explained by the promotion of proton formation and by the absorption properties of magnesium cations as well as by their localization in cations as well as by their localization in the crystal lattice of the zeolite.

Abstract

Исследованы превращения 1-метилнафталина на магниевых формах цеолита NaY с разной степенью йонного обмена и разного соотношения Si/Al при температурах 310 и 350°C. Все образцы проявляют высокуй активность в реакции позционной изоперизации. Изменения наблюдаемые в каталитической активности объясняются протонирующими и адсорбционными свойствами магниевых катионов, а также их локализацией в кристаллической решетке цеолита.
