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