Abstract

Activation of RuCl3-impregnated silica by nitrogen-hydrogen tratment at high temperature, up to 700 °C, is superior to calcination of the material prior to reduction. Sintering hardly occurs. In addition, activity measurements, based on the liquid phase hydrogenation of benzene, and thermogravimetric analysis suggest a favorable (chemical) interaction between ruthenium and silica.

Abstract

Активация силикагеля, пропитанного RuCl3 обработкой при высоких температурах до 700°C азотом и водородом оказывается лучшим прокаливания материала до восстановления. Усадка почти не набдюдается. Измерения активности, основанные на жидкофазном гидрировании бензола, а также термогравиметрический анализ указывают на благоприятное (химическое) взаимодействие между рутением и силикагелем.
