UNSUPPORTED AND SUPPORTED NON-PROMOTED RUTHENIUM SULFIDE CATALYST WITH HIGH CATALYTIC ACTIVITY FOR HYDROCARBON HYDROTREATMENTS AND ITS METHOD.

摘要

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.
