摘要：

A catalyst of Ni supported on alumina coated monolith has been prepared, characterized and tested in NH3 decomposition. The characterization of the catalyst by XPS and TPR showed that there is no formation of aluminates after catalyst use. It is studied the effect of the space velocity, by varying the feed flow rate and the catalyst's length. Some evidences are shown about the reaction inhibition by produced H-2 and about the reasons for the better performance of the monolith than packed bed catalyst.
