Modern catalysts of deep hydrotreatment in the production of low-sulfur diesel fuels at Russian oil refineries according to Euro-3 and Euro-4 standards

Abstract

The production of diesel fuels with sulfur contents according to Euro-3 and Euro-4 standards at Russian oil refineries requires the replacement of catalysts by more active ones without reconstructing the existing hydrotreating units. The majority of Russian catalysts can be used for the production of diesel fuels containing 350 ppm S and more. For the production of fuels with less than 50 and 10 ppm residual sulfur, however, last generation catalysts should be used, whose surface compounds are highly active Co(Ni)-Mo-S phases of the second type. A typical representative of these catalysts is the Russian IC-GO-1 catalyst, which has been manufactured since 2007 by ZAO Industrial Catalysts under the license of Boreskov Institute of Catalysis, Siberian Branch, Russian Academy of Sciences. The characteristics of hydrotreatment ensured by the developer and producer were confirmed during the commercial use of the catalyst at OAO Saratov Oil Refinery. The production of IC-GO-1 can reach 600 t per year, which is sufficient for the re-equipment of 10 standard Russian hydrotreating units.
