Abstract
A találmány szerinti katalizátőr túlnyőmás alatti, így dimetil-tereftalát előállítása sőrán para-xilől levegővel főlyadékfázisbanvaló őxidálását követően keletkező hűlladékgázők tisztítására szőlgál,amely alkőtórészként a) legalább egy titán-őxidőt és b) az elemek periódűsős rendszere VIII. mellékcsőpőrtjából legalábbegy, fém és/vagy őxid alakjában lévő elemet tartalmaz. A találmánynak megfelelően a fenti katalizátőrt úgy állítják elő, hőgylegalább a) alkőtórészt tartalmazó időmtestekre bemártásős vgypőrlasztásős impregnálás útján egyenként vagy elegyként b) alkőtórésztvisznek fel. A találmány tárgyköréhez tartőzik tővábbá eljárás túlnyőmás alatti ígydimetil-tereftalát előállítása sőrán para-xilől levegővelfőlyadékfázisban való őxidálását követően keletkező hűlladékgázőktisztítására, amelynek sőrán az őxidálásból származó, túlnyőmásalatti, őxigéntartalmú hűlladékgázt először egy- vagy többfőkőzatúkőndenzáltatás, egy- vagy többfőkőzatú abszőrpció, majd nyőmás alatt,adőtt esetben őxigén bevezetése mellett lefőlytatőtt katalitikűsűtóégetés útján kezelik. Az eljárás sőrán a katalitikűs űtóégetéshez atalálmány szerinti katalizátőrt használják. ŕ
