Abstract

POSTUPAK DOBIJANJA KATALIZATORA ZA OKSIDACIJU ETILENA U ETILENOKSID u gasnoj fazi, koji obuhvata faze: a) impregnisanja porozne podloge sa rastvorom jedinjenja srebra dovoljno da obezbedi 3 do 25 mas.% srebra na podlozi i odvajanje impregnisane podloge iz pomenutog rastvora; b) zagrevanje impregnisane podloge tokom vremena dovoljnog da se proizvede aktivirani katalizator; c) impregnisanja aktiviranog katalizatora sa rastvorom koji sadrzi jedinjenje alkalnog metala u kolicini dovoljnoj da snizi aktivnost i selektivnost aktiviranog katalizatora radi dobijanja katalizatorskog prekursora, pomenuti alkalni metal je izabran iz grupe koja se sastoji od natrijuma, kalijuma, cezijuma i rubidijuma; i d) termickog tretiranja katalizatorskog prekursora radi reaktiviranja prekursora da produkuje aktivni katalizator, naznacen time, sto se tretiranje katalizatorskog prekursora sastoji od faza: a) postavljanje katalizatorskog prekursora u pec; b) ispunjavanje katalizatora u pomenutoj peci sa inertnim gasom tokom dovoljnog perioda vremena radi izmestanja celokupnog vaz-duha unutar poci i unutar katalizatorskog prekursora; c) zagrevanje katalizatora u peci do temperature izmedju 500 i 700°C (npr. oko 600°C) tokom perioda od 0,25 do 1,5 casova (npr. oko jednog casa) dok se nastavlja ispunjavanje sa pomenutim inertnim gasom; d) kontrolisanje temperature katalizatora u peci pri temperaturi ravnoteznog stanja izmedju 500 i 700°C (npr., oko 600°C) tokom perioda od 0.1 do 4.5 casova (npr., 10-45 minuta) uz nastavljanje ispunjavanjem sa inertnim gasom; i e) hladjenje pomenutog katalizatora do sobne temperature uz nas-tavljanje ispune inertnim gasom. Prijava sadrzi jos 1 nezavisan i 12 zavisnih zahteva.
