Indlela ye-oxidation ye-Air yindlela yokusebenzisa ioksijini emoyeni iyokwayiwai-ceriumukubiza phantsi kweemeko ezithile. Le ndlela ibandakanya ukuqokelela i-fluorocarbon cerium ye-cerium ore, inqabile yomhlaba onqabileyo (olwaziwa ngokuba yi-oxidation) okanye ukonakalisa i-oxidation) okanye ukonakalisa i-oxidation (i-oxidation yomhlaba) ye-oxidation (i-oxidation yomhlaba) ye-oxidation (i-oxidation yomhlaba) ye-oxidation.
I-1, i-oxidation
I-Gloorocarbon Cloorocarbon igxile emoyeni nge-500 ℃ okanye igquma iBailinebol elinqamlezileyo kwi-sodium carbonate emodi kwi-600-700 ℃. Ngexesha lokungalunganga kweMinerali ye-Dure, i-cerium kwi-minerals inyanzelekile ukuba inyanzeliswe. Iindlela zokwahlulahlulai-ceriumUkusuka kwiimveliso ezisisiseko kubandakanya umhlaba onqabileyo we-sulfate palfate indlela yetyuwa, i-Solvent Indlela yokukhuthaza, njl.
Ukongeza kwi-oxidation ye-oxidation yeumhlaba onqabileyoGxila, ityiwa njengendawo enqabileyo ye-oxiler kunye ne-carbonate ye-carbonate ye-ristbonate ye-Airphecation kwindawo yomoya, kwaye i-cerium inyanzelwa kwi-CEO2. Ukuqinisekisa ukusweleka komxubo onqabileyo we-oxide oxiyayo, amaqondo obushushu amaninzi akufuneki ukuba aphakame kakhulu, ihlala iphakathi kwe-700 ne-800 ℃. I-oxide inokuthi ichithwe kwi-1-1.5mol / l isalfuric acid okanye i-4-5mol / l nitric Acid Stols. Xa ubopha i-oid ore nge-sulfuric acid kunye ne-nitric acid, i-hirium ikakhulu ingena kwisisombululo kwifom ye-tetravally. Okwangaphambili kubandakanya ukufumana isisombululo somhlaba onqabileyo esine-50g / l Remo malunga ne-45 ℃, kwaye emva koko uvelise indlela yokukhupha i-pp24; Le yokugqibela ibandakanya ukulungiselela isisombululo somhlaba onqabileyo esine-POO ye-150-200g / l kwiqondo lokushisa le-80-85 ℃, kwaye emva koko usebenzisa i-TBP yokukhupha i-TBP.
Xa umhlaba onqabileyo we-oxide oxizayo uchithwe nge-dilutric acid okanye i-nitric acid, i-CEO2 i-incolble. Ke ngoko, isixa esincinci se-hydrofluoricioric acid kufuneka yongezwe kwisisombululo njengeyona nto iphambili kwinqanaba lokuchithwa kwe-ceoo2.
I-2, i-oxidation yoMoya
Beka i-hydroxide enqabileyo kwiziko elomileyo kwaye liyisiphazise phantsi kweemeko ezinomoya kwi-100-120 ℃ kwiiyure ezili-16 ukuya kwezili-23. Impendulo ye-oxidation imi ngolu hlobo lulandelayo:
I-4CE) 3 + 2h2o = 4CE (O) 4
Inqanaba le-oxidition ye-cerium linokufikelela kwi-97%. Ukuba iqondo lobushushu le-oxidation liye landa kwi-140 ℃, ixesha le-oxidation linokupheliswa kwiiyure ezingama-4-6, kwaye inqanaba le-oxidation linokufikelela kwi-97% 98%. Inkqubo yomoya eyomileyo yenkqubo ivelisa inani elikhulu lothuli kunye nokuhlwempuzeka, ezisetyenziswa ngoku kusetyenziswa ilabhoratri.
I-3, i-oxidation yomoya
Hlanganisa umhlaba onqabileyo wamanzi ngamanzi ukwenza isilayidi, ulawule i-Reo gxini kwi-50g / l, yazisa umoya kwi-curium ukuya kwi-tirium ye-tirium ukuya kwi-tirium ye-tirium. Ngexesha lenkqubo ye-oxidation, ukuvela kwamanzi kuyinto enkulu, ke inani elithile lamanzi kufuneka longelwe ngalo naliphi na ixesha ukugcina ulwalamano oluzinzileyo lomhlaba onqabileyo. Xa i-40l yesilayidi i-oxidod kwi-batch nganye, ixesha le-oxidation li-4-5 iiyure, kwaye inqanaba le-oxidation le-Crium linokufikelela kwi-98%. Xa i-8m3 yoMhlaba onqabileyo we-Hydroxride i-oxidride i-oxidd ihamba ixesha ngalinye, inqanaba lokuhamba komoya liyi-8-12m
Iimpawu zeyona ndlela ye-oxidation yasemoyeni ye-Aatmossic ye-Air Kio: Inqanaba le-oxidation ephezulu ye-cirium, iziphumo ezinkulu, iimeko ezifanelekileyo zomsebenzi, kwaye le ndlela ilula isetyenziswa kumzi-mveliso ukuvelisa i-crium diokium ye-crade dioxide.
4, i-oxidation yomoya
Ngaphantsi koxinzelelo oluqhelekileyo, i-oxidation ye-air thatha ixesha elide, kwaye abantu banqumle ixesha le-oxidation ngokusebenzisa uxinzelelo. Ukonyuka koxinzelelo lomoya, oko kukuthi, ukwanda koxinzelelo lwenxalenye yeoksijini kwinkqubo, kulungele ukutshitshiswa kweoksijini kwisisombululo kunye nokuxabana kweoksijini yomhlaba onqabileyo, oko kuyakhawuleza inkqubo ye-oxidation.
Hlanganisa umhlaba onqabileyo we-hydroxide ngamanzi ukuya kuma-60g / L, uhlengahlengise i-PH ukuya kwi-13 ye-sodium hydroxide, iphakamise uxinzelelo kwi-0,4MPA, kunye ne-oxiving ngeyure enye. Inqanaba le-oxidition ye-cerium linokufikelela ngaphezulu kwe-95%. Kwimveliso yokwenyani, i-Oxidation Suble Subre Dhydroxide ifunyenwe ngu-Alkali Guqula ukuguquguquka komhlaba onqabileyo we-sodium slosium cledium cer ityiwa ityuwa. Ukwenzela ukuthoba inkqubo, ukucaciswa kwesodi yomhlaba onqabileyo we-Suldium ye-Sulfate kunye nesisombululo se-Alkaline sinokongezwa kwitanki yokucinezelwa kwe-oxidation, ukugcina uxinzelelo oluthile kunye nobushushu obuthile. Umoya okanye i-thessigen etyebileyo inokwaziswa ukuguqula umhlaba onqabileyo kwityuwa enqabileyo kwi-Hydroxides, kwaye kwangaxeshanye, oh (oh) 4.
Phantsi kweemeko ezixineneyo, inqanaba lokuguqulwa kwe-alkali yetyuwa enzima, i-oxidition ye-cirium, kunye nenqanaba le-oxidition ye-Criium yonke iphuculwe. Emva kwemizuzu engama-45 yokuphendula, ireyithi yokuguqula i-Alkali i-Alkali kunye nenqanaba le-oxidation ye-Cerium ifikelele kwi-96%.
