    Iridium Sulfide and Ir Promoted Mo Based Catalysts.

  • Original language description

    Data covering the preparation and catalytic properties of Ir sulfide catalysts in hydrotreating reactions have been reviewed. Ir sulfide belongs to the most active members of the 3rd row noble metal sulfides. The specific activity of a dispersed Ir sulfide in reactions of model compounds ( thiophene, indole, pyridine, quinoline) is greater than that of conventional catalysts. Sulfided Ir in an amount of 0.5 wt.% is an efficient promoter of the Mo/Al2O3 catalysts. Modification of the NiMo/Al2O3 catalystsby Ir usually led to the decrease of HDS activity and the increase of HDN activity.

    Sulfid Ir a Mo katalyzátory promotované Ir.

  • Czech description

    Byla shrnuta data pokrývající přípravu a katalytické vlastnosti Ir sulfidických katalyzátorů v hydrorafinačních reakcích. Sulfid Ir patří k nejaktivnějším členům 3.periody vzácných kovů. Specifická aktivita dispergovaného sulfidu Ir je v reakcích modelových sloučenin vyšší než aktivita konvenčních katalyzátorů. Ir v množství 0,5 % je účinným promotorem Mo/Al2O3. Modifikace NiMo/Al2O3 vede obvykle k poklesu HDS a zvýšení HDN.
