Oxidation Catalyst & Liquid chikamu oxidation catalyst
Kana ethylene uye propylene inowanikwa kubva petroleum hydrocarbon cracking inoshandiswa sepolymerization zvinhu, kusarudza hydrogenation kunodiwa kubvisa tsvina yakadai sealkyne, diene, carbon monoxide, carbon dioxide uye oksijeni, pasina kurasikirwa kweolefin.Iyo catalyst inoshandiswa inowanzo palladium, platinamu kana nickel, cobalt, molybdenum, nezvimwewo, pane alumina.Sarudza hydrogenation catalysts ine zvinhu zvakasiyana-siyana zvinogona kuwanikwa nekudzora huwandu hwezvinhu zvinoshanda, nzira yekugadzira yekutsigira uye catalyst.Zvimwe zvakaita sekupaza peturu kunatsa, nitrobenzene hydrogenation kuderedzwa kusvika aniline, hydrogenation catalyst.
Catalyst yeyakadzika hydrogenation kune yakazara makomisheni.Zvakadai sebenzene hydrogenation kune cyclohexane ine nickel alumina catalyst, phenol hydrogenation kusvika cyclohexanol, ine dinitrile hydrogenation kune hexdiamine ine nickel catalyst.
Kushandisa silicon carbide kana α -alumina serutsigiro (ine shoma shoma ye barium oxide se cocatalyst).Mushure mekuenderera mberi kwekuvandudza kwecatalyst uye process mamiriro, huremu goho re ethylene rakapfuura 100%.
A catalyst yakapfapfaidzwa pasilicon carbide kana corundum yeoxidation yeo-xylene kune phthalic anhydride.A catalyst yakagadzirwa nekupfapfaidza iyo inoshanda component yevanadium-molybdenum series oxides pacorundum yeoxidation yebenzene kana butane kune maleic anhydride.Kuvandudzwa kwerudzi urwu rwe catalyst ndiko kugadzirwa kweakawanda-component, masere echikamu catalysts akaonekwa.Chimiro chemutakuri chinoshandurwa zvakare kubva kudenderedzwa kuenda kudenderedzwa, semicircle kuti ifambise kupisa kupisa.Iyo yakajairika maitiro ndeyekutevera yakakwira mitoro, goho repamusoro uye kuchena kwakanyanya kwezvigadzirwa.
Zvakadai semethanol oxidation kuita formaldehyde nesirivha - pumice (kana alumina), iron oxide - molybdenum oxide uye electrolytic sirivheri catalyst.
Mumakore ekuma1960, chigadziriso chine bismuth-mo-phosphorus compound oxide catalyst yakagadzirwa.Acrylonitrile inogona kugadzirwa mune imwe nhanho nekuwedzera propylene, ammonia uye mweya pane catalyst.Kuti uvandudze kusarudzwa uye goho uye kuderedza kusvibiswa kwezvakatipoteredza, nyika dzakasiyana-siyana dziri kugara dzichivandudza chinokonzera, uye mamwe macatalyst matsva ane anosvika gumi neshanu marudzi ezvinhu.Oxygen chlorination catalyst, iyo 60's yakagadzira copper chloride alumina catalyst, mu fluidized bed reactor kuburikidza ne ethylene, hydrogen chloride uye mweya kana oxygen inogona kuwana dichloroethane.Dichloroethane yakaitwa pyrolyzed kugadzira vinyl chloride monomer.Iyi nzira inobatsira pakuvandudzwa kwePVC munzvimbo dzinodhura magetsi uye petrochemicals inogadzirwa, nzira yekugadzira yekutsigira uye catalyst.Zvimwe zvakaita sekupaza peturu kunatsa, nitrobenzene hydrogenation kuderedzwa kusvika aniline, hydrogenation catalyst.
Liquid phase oxidation catalyst
Pane kunyanya:
(1) Ethylene, propylene oxidation acetaldehyde, acetone (Wacker nzira), ine zvishoma palladium.chloride copper chloride solution catalyst, kuburikidza neolefin, mweya kana oxygen, mushure meimwe kana maviri nhanho yekuita kuti uwane inodiwa.mishonga ine oxygen.Izvo zvisingabatsiri ndiko kukanganisa kwakakomba kwemaitiro ekuita.
(2) Zvinonhuhwirira divi cheni oxidationye aryl acid catalyst, yakadai sep-xylene muacetic acid solution ine cobalt acetate uye shoma shoma yeammonium bromide.kudziyisa, kugadzirwa kwemhepo oxidation terephthalic acid, asi kukanganisa kwakakomba kwemaitiro ekushandisa.
