I. ABSTRACT
New economical and ecological constraints call for the development of more active catalysts than the conventional ones for all hydrotreating reactions. In this respect, ruthenium sulfide catalysts have received attention due to their prominent catalytic activities. The present paper gives an overview of the studies carried out in our group concerning the properties of ruthenium sulfide supported on alumina or dispersed in zeolite, its ability to form solid solutions either in the supported or unsupported state and the utilization of ruthenium sulfide as a model compound for fundamental studies dealing with the interaction of reactants and sulfide phases.
