Oxidation Catalyst & Suavai vaega oxidation catalyst
Oxidation Catalyst & Suavai vaega oxidation catalyst
A fa'aaogaina le ethylene ma le propylene e maua mai le suau'u hydrocarbon ta'e e fai ma mea polymerization, e mana'omia le fa'aeleeleina filifilia e aveese ai fa'aleaga e pei ole alkyne, diene, carbon monoxide, carbon dioxide ma le okesene, e aunoa ma le leiloa ole olefin.O le faʻaaogaina e masani lava o le palladium, platinum poʻo le nickel, cobalt, molybdenum, ma isi, i luga ole alumina.Fa'ato'a fa'atosina filifilias fa'atasi ai ma meatotino eseese e mafai ona maua e ala i le fa'atonutonuina o le aofa'i o vaila'au malosi, le auala gaosi o le lagolago ma le fa'amalosi.O isi e pei o le ta'e penisini faamamaina, nitrobenzene hydrogenation faaitiitia i le aniline, hydrogenation catalyst.
Fa'atosina mo le loloto o le hydrogenation i fa'aputuga tumu.E pei o le hydrogenation benzene i le cyclohexane ma le nickel alumina catalyst, phenol hydrogenation i le cyclohexanol, e iai le dinitrile hydrogenation i le hexdiamine ma le nickel catalyst.
Fa'aaogaina o le silicon carbide po'o le α-alumina e fai ma lagolago (fa'atasi ai ma sina vaega itiiti o le barium oxide e fai ma cocatalyst).A maeʻa faʻaauau le faʻaleleia atili o le faʻaogaina ma le faʻagasologa o tulaga, o le mamafa o le ethylene ua sili atu i le 100%.
O se fa'amamafa e su'iina i luga o le silikoni carbide po'o le corundum mo le fa'ama'iina o le o-xylene i le phthalic anhydride.O se fa'amamafa ua saunia e ala i le sasaina o le vaega malosi ole vanadium-molybdenum series oxides ile corundum mo le fa'ama'iina ole benzene po'o le butane ile maleic anhydride.O le faʻaleleia atili o lenei ituaiga faʻamalosi o le atinaʻeina o le tele-vaega, e valu vaega faʻamalosi ua faʻaalia.O foliga o le va'a e suia fo'i mai le lapotopoto i le lapotopoto, semicircle e fa'afaigofie ai le fa'afefe o le vevela.O le masani masani o le tulituliloaina o uta maualuga, maualuga maualuga ma maualuga le mama o oloa.
E pei o le methanol oxidation i formaldehyde ma siliva - pumice (po'o alumina), iron oxide - molybdenum oxide ma electrolytic silver catalyst.
I le 1960s, na fausia ai se catalyst o loʻo iai le bismuth-mo-phosphorus compound oxide catalyst.Acrylonitrile e mafai ona tuufaatasia i le laasaga e tasi e ala i le faaopoopo o le propylene, amonia ma le ea i luga o le catalyst.Ina ia faʻaleleia le filifilia ma le maua ma faʻaitiitia le faʻaleagaina o le siosiomaga, o atunuʻu eseese o loʻo faʻaleleia pea le faʻamalosi, ma o nisi mea fou e aofia ai le 15 ituaiga elemene.Oxygen chlorination catalyst, o le 60's atia'e copper chloride alumina catalyst, i totonu o le fa'amea moega fluidized e ala i le ethylene, hydrogen chloride ma le ea po'o le okesene e mafai ona maua le dichloroethane.O le Dichloroethane na fa'a'u'umi e maua ai le monomer vinyl chloride.O lenei metotia e aoga mo le atinaʻeina o le PVC i nofoaga e taugata ai le eletise ma faʻalauteleina petrochemicals, o le gaosiga o auala lagolago ma faʻamalosi.O isi e pei o le ta'e penisini faamamaina, nitrobenzene hydrogenation faaitiitia i le aniline, hydrogenation catalyst.
Suavai vaega oxidation catalyst
E tele lava:
(1) Ethylene, propylene oxidation acetaldehyde, acetone (Wacker method), faatasi ai ma sina vaega itiiti o le palladiumchloride copper chloride solution catalyst, e ala i le olefin, ea poʻo le okesene, pe a uma le tasi pe lua laasaga o le tali e maua ai le manaʻomia.mea e maua ai le okesene.O le fa'aletonu o le fa'aleagaina tele o mea faigaluega fa'afoliga.
(2) oxidation filifili itu manogimo aryl acid catalyst, e pei o le p-xylene i le acetic acid solution ma cobalt acetate ma sina vaega itiiti o le ammonium bromidefaʻamafanafanaina, ea oxidation gaosiga terephthalic acid, ae matuia corrosion o meafaigaluega tali.
