摘要：

The potential of the temperature programmed sulfiding (TPS) technique is enlightened using commercial type of CoO-MoO3/Al2O3 catalysts. A modified TPS procedure is proposed to simulate more closely industrial sulfiding procedures. A relation is found between the amount of sulfidable cobalt ions and the hydrodesulfurization activity of CoO-MoO3/Al2O3 catalysts, calcined between 823 and 873 K and containing at most 4 wt % CoO. Provided (i) typically industrial calcination temperatures are used and (ii) the catalysts do not contain phosphorus, TPS is a direct method to estimate the amount of cobalt which shows hardly any catalytic activity.
