Abstract

The activity in n-butane hydrogenolysis of Rh/TiO2 (0.6 wt.% Rh) catalysts prepared by ion exchange and reduced at different heating rates is reported. The heating rate has no major effect on the properties of the catalysts (similar dispersions and activities are achieved). Carbonaceous residues formed at high temperature are removed by hydrogen at room temperature, thus leading to recovery of the activity.

Abstract

Описывают активность катализатора Rh/TiO2 (0,6 вес.% Rh), приготовленного ионным обменом и восстановленного при различных скоростях нагрева, в гидрогенолизе н-бутана. Скорость нагрева не влияет на свойства катализатора: получены одинаковые дисперсности и активности. Углекислые остатки, образующиеся при высоких температурах, удаляют водородом при комнатной температуре, регенерируя, таким образом, активностя.
