Abstract

Diffuse reflectance spectra have been recorded for WO3/SiO2 and WO3/γ-Al2O3 catalysts after various steps of treatment of these samples, in particular, after treatment of WO3/SiO2 by HCl. It is shown that for WO3/γ-Al2O3 the temperatures of the onset of reaction and WO3 reduction coincide.

Abstract

Измерены спектры диффузного отражения катализаторов диспропорционирования пропилена WO3/SiO2 и WO3/γ-Al2O3 для различных стадий обработки зтих образцов, в частности, для случая обработки WO3/SiO2 парами HCl. Покзано, что в случае WO3/γ-Al2O3 температуры начала реакции и восстановления окиси вольфрама совпадают.
