CATALYTIC SYSTEM AND RECOMBINATION DEVICE FOR RECOMBINING HYDROGEN AND OXYGEN USED IN PARTICULAR FOR NUCLEAR POWER PLANTS Russian patent published in 2002 - IPC

FIELD: nuclear power engineering. SUBSTANCE: catalytic system has metal carrying sheet of high heat conductivity covered in first zone 12 with layer of first noble catalytic metal 13 and in second zone 14, with layer of second noble catalytic metal 15. First and second zones 12 and 14 are to be better located on same side of sheet. Noble metals 13 and 15 best suited for the purpose are platinum and palladium. Carrying sheet is made of stainless steel and has additional catalytic layer. Recombination device has set of catalytic systems held in holders 24, 26. Gas flow 6 is first brought in contact with noble metal 15 in second zone 14 and then with first noble metal 13 in first zone 13. Recombination device is capable of operating at low temperatures. EFFECT: enhanced resistance to poisoning and to high temperatures. 23 cl, 2 dwg
