Oxidation Catalyst & Liquid phase oxidation catalyst
Mgbe ethylene na propylene enwetara site na petroleum hydrocarbon cracking na-eji dị ka ihe polymerization, a chọrọ hydrogenation nhọrọ iji wepụ ihe adịghị ọcha dị ka alkyne, diene, carbon monoxide, carbon dioxide na oxygen, na-enweghị ọnwụ nke olefin.Ihe na-eme ka a na-ejikarị eme ihe bụ palladium, platinum ma ọ bụ nickel, cobalt, molybdenum, wdg, na alumina.Nhọrọ hydrogenation ihe mkpalis nwere ihe dị iche iche nwere ike ịnweta site n'ịchịkwa ọnụ ọgụgụ nke ihe na-arụ ọrụ, usoro mmepụta nke nkwado na ihe na-akpali akpali.Ndị ọzọ dị ka mgbawa mmanụ ụgbọala, mbelata nitrobenzene hydrogenation na aniline, hydrogenation catalyst.
Ihe na-eme ka hydrogenation miri emi banye na ogige juru eju.Dị ka benzene hydrogenation ka cyclohexane na nickel alumina catalyst, phenol hydrogenation ka cyclohexanol, nwere dinitrile hydrogenation ka hexdiamine na nickel catalyst.
Iji silicon carbide ma ọ bụ α-alumina dị ka nkwado (na obere barium oxide dị ka cocatalyst).Mgbe nkwalite na-aga n'ihu nke ihe na-akpata na ọnọdụ usoro, mkpụrụ nke ethylene dị arọ agafeela 100%.
Ihe na-akpali akpali fesara na silicon carbide ma ọ bụ corundum maka oxidation nke o-xylene na phthalic anhydride.Ihe na-akpali akpali nke a kwadebere site n'ịfesa ihe na-arụ ọrụ nke usoro vanadium-molybdenum oxides na corundum maka oxidation nke benzene ma ọ bụ butane na anhydride maleic.Ọganihu nke ụdị ihe na-eme ka a na-emepụta ihe na-emepụta ihe dị iche iche, ihe ntinye ihe asatọ apụtala.A na-agbanwekwa ọdịdị nke ụgbọelu ahụ site na okirikiri gaa na okirikiri, ọkara okirikiri iji kwado nnyefe okpomọkụ.Ihe na-emekarị bụ ịchụso ibu dị elu, nnukwu mkpụrụ na ịdị ọcha nke ngwaahịa.
Dị ka methanol oxidation n'ime formaldehyde na ọlaọcha - pumice (ma ọ bụ alumina), iron oxide - molybdenum oxide na electrolytic silver catalyst.
N'afọ ndị 1960, e mepụtara ihe na-emepụta ihe nwere bismuth-mo-phosphorus compound oxide catalyst.Enwere ike ijikọ Acrylonitrile n'otu nzọụkwụ site n'ịgbakwụnye propylene, amonia na ikuku n'ime ihe.Iji meziwanye nhọrọ na mkpụrụ na ibelata mmetọ gburugburu ebe obibi, mba dị iche iche na-emeziwanye ihe na-eme ka ihe na-eme ka ọ dịkwuo mma, ụfọdụ ihe ọhụrụ na-emepụta ihe nwere ihe ruru ụdị 15.Oxygen chlorination catalyst, 60's mepụtara ọla kọpa chloride alumina catalyst, na mmiri mmiri na-eme ihe ndina site na ethylene, hydrogen chloride na ikuku ma ọ bụ oxygen nwere ike nweta dichloroethane.Dichloroethane bụ pyrolyzed iji mepụta monomer vinyl chloride.Usoro a bara uru maka mmepe nke PVC na mpaghara ebe ọkụ eletrik dị oke ọnụ na petrochemicals na-emepụta, usoro mmepụta nke nkwado na ihe na-akpali akpali.Ndị ọzọ dị ka mgbawa mmanụ ụgbọala, mbelata nitrobenzene hydrogenation na aniline, hydrogenation catalyst.
Ihe na-akpali akpali nke akụkụ mmiri mmiri oxidation
E nwere tumadi:
(1) Ethylene, propylene oxidation acetaldehyde, acetone (usoro Wacker), na obere palladium.chloride ọla kọpa chloride ngwọta catalyst, site na olefin, ikuku ma ọ bụ oxygen, mgbe otu ma ọ bụ abụọ nzọụkwụ nke mmeghachi omume iji nweta ihe achọrọ.ogige ndị nwere oxygen.Ọdịmma ahụ bụ nnukwu mmebi nke akụrụngwa mmeghachi omume.
(2) oxidation n'akụkụ yinye aromaticmaka aryl acid catalyst, dị ka p-xylene na acetic acid ngwọta na cobalt acetate na obere ego nke ammonium bromide.kpo oku, ikuku oxidation mmepụta terephthalic acid, mana nnukwu corrosion nke akụrụngwa mmeghachi omume.
