Abstract

POSTUPAK ZA PROIZVODNJU AMONIJAKA, u sinteznom kolu u kome kombinovani sintezni gas koji sadrži od 35 do 50 vol% vodonika, od 25 do 55 vol% azota, od 1 do 5 vol.% amonijaka i od 2 do 25 vol.% metana i argona, reaguje sa katalizatorom za sintezu amonijaka pod uslovima sinteze i konverzijom nastaje gas koji sadrži od 20 do 40 vol.% vodonika, od 25 do 60 vol.% azota i od 10 do 18 vol.% amonijaka koji se odvaja, naznačen time, što se kombinovani sintezni gas dobija uzajamnim mešanjem svežeg sinteznog gasa koji sadrži vodonik i azot u molarnom odnosu vodonika prema azotu izmedju 1.7 i 2.5 i vodonika obogaćenog reciklovanog gasa koji sadrži vodonik i azot u molarnom odnosu vodonika prema azotu izmedju 0.5 i 1.7 pri volumetrijskom odnosu brzine protoka vodonikom obogaćenog reciklovanog gasa prema brzini protoka svežeg sinteznog gasa od 2.2 do 5.7 i ovako dobiveni kombinovani sintezni gas ima molarni odnos vodonika prema azotu izmedju 0.8 i 1.8, pri čemu se kombinovani sintezni gas dovodi u dodir sa visoko aktivnim katalizatorom za sintezu amonijaka na temperaturi izmedju 315 C i 400 C i pod pritiskom izmedju 4.9 MPa i 14.71 MPa. Prijava sadrži još 9 patentnih zahteva.
