PP-III-32It is established, that created low-percentage ruthenium-carbon catalystsRu-CeO2/Sibunit are surpassed in activity the catalysts-analogues with the high content of anactive component, are steady in oxidation of organics (200 o C, 50 bar O 2 ), practically are notsubject to washout of an active component, and their activity is kept by a constant during longperiod of tests in a trickle bed reactor (Fig. 1).S CO20,70,60,50,40,30,20,1A B C D E0 - 00,00 50 100 150 200 250 300t, hFig. 1.

Line 0-0 - initial level ofactivity.The systematical researches are currently pursuing in Boreskov Institute of Catalysis haveallowed to solve problems of creation of the catalyst for industrial application and to developon its basis highly effective catalytic technologies of wastewater treatment from various toxiccomponents.Acknowledgment: The financial support of this study by INTAS (grant Nr.05-1000007-420) and the Russian Foundation for Basic Research (grant 05-03-22004-CNRS_а) is gratefully acknowledged.References:1.
