Abstract

In hydrodesulfurization of 35S-labeled dibenzothiophene over alumina-supported ruthenium sulfide-cesium catalysts, the role of cesium was elucidated by tracing the behavior of 35S on the working ruthenium catalysts; the addition of cesium increased the catalytic activity by strengthening Ru-S bonds of ruthenium sulfide. It is suggested that there is an optimum Ru-S bond strength to obtain the high catalytic activity.
