Abstract: The present invention relates to a synthesis method for unsupported and supported ruthenium base (RuS2) catalysts from a ruthenium complex precursor, which is decomposed and activated by a simple activation process; these steps provide a catalyst with very high catalytic activity, in addition the incorporation of ruthenium complex precursor to a support by methods of incipient and wet impregnating is described; the obtained catalytic activities in this invention are in the order of 100 times the molybdenum sulfide catalyst without support and without promoter, 14 times the industrial supported catalyst, and 5 times the activity of the currently most active commercial unsupported catalyst.

Abstract: The present invention relates to synthesis method of a family of ruthenium sulfide catalysts promoted with an added additional metal, unsupported (M/RuS2) and supported (M/RuS2/support). The obtained catalysts exhibit a high catalytic activity in hydrotreating or hydroprocessing (HDT) of hydrocarbons, mainly hydrodesulfuration, hydrodenitrogenation, and hydrodeoxigenation. The impact of the present invention for application in the commercial context, lies in the high catalytic activity of the obtained catalysts, which is far superior to the existing commercial catalysts, as well as the simplicity of the synthesis method, which will affect the quality of the products obtained in the oil industry, allowing to meet the environmental standards imposed by current legislations.
