Abstract

The elution of hydrogen and water desorbed from a MoO3Al2O3 catalyst reduced with hydrogen at 550°C was investigated at 550°C and at O°C. Only hydrogen may be eluted at 550°C, and neither hydrogen may be eluted at 550°C, and neither hydrogen, nor water desorbs at O°C. The reversibly adsorbed hydrogen is responsible for the deactivation of the catalyst used in disproportion ation of propylene at 0–80°C without evacuation at elevated temperatures after reduction.

Abstract

Злюирование водорода и воды, десорбированных с католизатора MoO3/Al2O3, восстановленного водородом при 550°C, было исследовано при 550 и 0°C. При 550°C злюируется лишь водород, а при 0°C ни водород, ни вода не десорбируются. Адсорбированный обратимо водород вызывает дезактивацию катализатора, используемого в реакции диспропорционирования пропилена при 0–80°C без откачивния, при повышенных температурах после восстановления катализатора.
