Mhepo oxidation nzira inzira ye oxidation iyo inoshandisa oksijeni mumhepo kune oxidizeceriumkune tetravalent pasi pemamwe mamiriro. Iyi nzira kazhinji inosanganisira kugochera Fluorocarbon Cerium Cerium Cerium Ore Oxacation, inozivikanwa soMhepo Oxidation) kana kuunza Mhepo Oxidation
1, kugopisa oxidation
Kubika fluorocarbon cerium cermencarte mumhepo pa500】 kana kuhukura iyo Baiyunebo risingaoneki pasi rinotarisa neSodium carbonate mumhepo na600-700 ℃. Munguva yekuora kwechiitiko chevashoma pasi zvichals, cerium mumaminerari ndeye oxidized kusvika kune tetravalent. Nzira dzekuparadzanisaceriumkubva pane zvigadzirwa zvisina kugadzirwa zvinosanganisira zvisingawanzo nyika sulfate kaviri munyu wenyuchi, solvent yekuwedzera nzira, nezvimwe.
Kuwedzera kune oxidation kuhukura kwerare pasifungisisa, munyu wakadai seanoshamisa pasi wepasi oxalate uye hara pasi carbonate yekudzora madhiri mumhepo, uye cerium iri oxidized to CEO2. Kuve nechokwadi chekushamisira kwakanyanya kwepasi ravheni revo OLIDS inogona kunyimwa muna 1-1.5MOL / L Sulfutic acid Solution kana 4-5mol / l nitric acid mhinduro. Paunenge uchisvetuka yakagochwa ore ne sulfutic acid uye nitric acid, cerium inonyanya kupinda mhinduro muchimiro cheTetravallent. Iyo yekutanga inosanganisira kuwana nyika isingawanzo sulfate mhinduro ine 50G / L REO atenderedza 45 ℃, uye wozogadzira cerium dioxide uchishandisa iyo P204 yekubvisa nzira; Iyo yekupedzisira inosanganisira kugadzirira mhinduro yepasi ine pasi ine remo ye150-200g / l pakudziya kwe80-85
Kana zvisingawanzo nyika Naizvozvo, chidiki chidiki che hydrofluorgic acid inoda kuwedzerwa kune mhinduro seyechivanhu mune imwe nhambureti yekunyungudika yekuvandudza solubility yeCOO2.
2, yakaoma mhepo oxidation
Isa iyo isingawanzo nyika hydroxide muchoto chomoto uye oxidhiise pasi pemamiriro ekunze pa100-120 × kwemaawa gumi nematanhatu. Iyo oxidation maitiro ndeye inotevera:
4CE (OH) 3 + O2 + 2H2O = 4CE (OH) 4
Iyo oxidation chiyero che cerium inogona kusvika 97%. Kana iyo oxidation tembiricha yakawedzera kusvika pa140 Iwo akaoma mhepo oxidation maitiro anogadzira huwandu hukuru hweruva uye hurombo hwemabasa emabasa, izvo zviri kunyanya kushandiswa mumarabhoritari.
3, empospheric yakanyorova mhepo oxidation
Sanganisa asingawanzo nyika hydroxide nemvura kuti iite slurry kusvika pamakumi mashanu, Munguva ye oxidation maitiro, kupepuka kwemvura kwakakura, saka imwe huwandu hwemvura inofanira kuwedzerwa chero nguva yekuchengetedza kusungirirwa kwakanyanya kwepasi. Kana 40l of slurry iri oxidized mune yega yega batch, iyo oxidation nguva ndeye maawa 4-5, uye iyo oxidation chiyero che casium inogona kusvika 98%. When 8m3 of Rare Pasi Pasi Hydroxide Slurry nguva imwe neimwe, iyo Mhepo kuyerera mari ndeye 8-12m3 / min
Hunhu hweMhepo yeAtmpheric Wet Air Oxidation Nzira yeChidium yeCerium, mamiriro akakura, mamiriro ezvinhu akareruka, uye nzira iyi inowanzoshandiswa muindasitiri kuburitsa cerium cerium dioxide.
4, yakamanikidzwa yakanyoroveswa mhepo oxidation
Pasi pekumanikidzwa kwakajairika, mhepo oxidation inotora nguva yakareba, uye vanhu vanopfupisa nguva yehodhi nekushandisa kumanikidza. Kuwedzera kwekumanikidzwa kwemhepo, ndiko kuti, kuwedzera kwechirevo cheokisijeni muhurongwa hweokisijeni mugadziriso uye kusiyana kwehusimbiso kusingaenzaniswi pasi pehusimbe.
Sanganisa asingawanzo nyika hydroxide nemvura kusvika pamakumi matanhatu, l, gadzirisa iyo sodium Hydroxide Iyo oxidation rate ye cerium inogona kusvika pamusoro pe95%. Mukugadzirwa chaiko, iyo oxidation mbichana zvinyorwa zvisingawanzoitika pasi hydroxide inowanikwa neAlkali kushandurwa kuburikidza nekunyorova kweKashoma Nyika Solium Sulfate Munyu waoma. Kuti ipfupise maitiro aya, iyo yekunyepedzera kwevanhu vepasi solium sulfate munyu uye alkaline solution inogona kuwedzerwa kune yakamanikidzwa kune tank Mhepo kana yakapfuma okisijeni inogona kuunzwa kushandura nyika isingawanzo mune iyo yakaoma yemunyu mune risingawanzo kuve nyika hydroxides, uye panguva imwe chete, o)
Pasi pemamiriro ekumanikidzwa, iyo alkali yekushandurwa kwemunyu yeiyo yakaoma munyu, iyo oxidation chiyero che casium, uye iyo oxidation mwero wechibvumirano zvese zvese zvakavandudzwa. Mushure memaminitsi makumi mana ekuita, huwandu hwekutendeuka hwemunyu wemunyu Alkali uye iyo oxidation rate ye cerium yakasvika kupfuura 96%.
