Usoro oxidation nke ikuku bụ usoro oxidation na-eji oxygen n'ikuku ka ọ dị na oxidizeoeridutotravalent n'okpuru ụfọdụ ọnọdụ. Usoro a na-agụnye ya na-egbu egbu na-etinye uche, nke a na-eji efe efe na ikuku (nke a na-eme ka ọ na-efe efe) maka oxidize.
1, a na-asa ahụ oxidition
Ahịhịa ahụ na-eme ka ikuku na-eme ka ikuku dị na 500 ℃ ma ọ bụ na-asa ahụ bekee dị ụkọ n'ụwa lekwasịrị anya na ikuku na 600-700 ℃. N'oge e deperium nke dị egwu, a na-eme ihe nkiri na mineral. Ụzọ maka ikewapụoeriduSite na ngwaahịa ndị a na-eme ka a na-eme ka ụwa na-agbasa ụzọ nnu nnu dị okpukpu abụọ, usoro ndọpụta na-agbanwe agbanwe, wdg.
Na mgbakwunye na oxidation na-amị mkpụrụ nkeỌdịda AlaGburugburu, nnu dị ka awara ookeoxte ma na-eme ka a na-awụ akpata nsogbu ikuku, a na-eji cerium oxidize na CEO2. Iji hụ na sogblity nke ngwakọta ụwa nke na-adịghị ahụkekọ site na ngwakọta, okpomọkụ ekwesịghị ịdị oke oke, na-abụkarị n'etiti 700 na 800 na 800 na 800 na 800. Enwere ike gbazee oxood na 1-1.5mol / l sulfuric acid ma ọ bụ 4-5mol / l nitric ard ngwọta. Mgbe ịkachasị a asara n'ọkụ ore na sulfuric acid na nitric acid, cerium na-abanye na ngwọta ahụ n'ụdị tetravalent. Onye nke mbụ na-agụnye inweta ụwa sulfate nke nwere 50g / l Reer na gburugburu 45 ℃, ma na-emepụta cearrium dioxide site na iji usoro p204; Nke ikpeazụ na-agụnye ịkwadebe ụwa ngwọta nke nwere 300-200g / l na okpomọkụ nke 80-85 ℃, wee jiri mmịpụta TBP iche kewapụ.
Mgbe a na-agbaji jọgburunụ ụwa na-agbaze site na agwakọta sulfuric acid ma ọ bụ nitric acid, onye isi adịghị ahụkarị. Ya mere, obere ego acid acid kwesịrị ịgbakwunye na ngwọta dị ka ihe na-eweta ihe na-eme ka emechaa na usoro mgbasa nke onye isi oche.
2, akọrọ ikuku na-efe efe
Debe mmiri hydroxide dị na nkụ na-akpọ nkụ ma oxidize ya n'okpuru ọnọdụ ikuku na 100-120 ℃ maka awa 16-24. Mmeghachi omume oxidation bụ ndị a:
4ce (oh) 3 + O2 + 2h2o = 4CE (Oh) 4
Oxidation ọnụego nke cerium nwere ike iru 97%. Ọ bụrụ na oge oxideration na-abawanye na 140 ℃, oge oxidation nwere ike belata 4-6 awa, na oxidation na-aba uru nke cerium nwekwara ike iru 97% ~ 98%. Usoro ikuku kpọrọ nkụ na-emepụta nnukwu uzuzu na ọnọdụ ọrụ dị mma, nke a na-ejikarị na laabu.
3, ikuku ikuku ikuku
Mix na mmiri na-eji mmiri eme ihe na-etolite, na-ejide reo iyaration ruo 85,35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35.35-0 N'oge oxidation usoro, mmiri mmiri dịtụ nnukwu ibu, yabụ, a ga-agbakwunye otu mmiri nke mmiri n'oge ọ bụla iji nọgide na-enwekwu itinye uche na-adịgide ma ọlị. Mgbe 40L nke slurry na -acha na oxiday ọ bụla, oge oxidation bụ 4-5 awa, na oxidation oxidation ọnụego nke cearrium nwere ike iru 98%. Mgbe 8M3 nke a na-ahụ anya mmiri hydride slidide oge ọ bụla, ọnụego ikuku na-abawanye ruo 15h, nke na-abawanye na 15h, nke na-abawanye nke cearrium nwere ike iru 97% ~ 98%.
Njirimara nke usoro ikuku ikuku ikuku ikuku ikuku dị: elu oxidation dị elu nke centium, nnukwu nrụpụta, ọrụ dị mfe na usoro a na-arụpụta ihe a na-eme.
4, nke ikuku ikuku na-efe efe
N'okpuru nrụgide nkịtị, oxidation ikuku na-ewe ogologo oge, ndị mmadụ na-ebelata oge oxidation site na iji nrụgide. Mmụba nke nrụgide ikuku, ya bụ, mmụba nke nrụgide oxygen na sistemụ, na-eme ka mgbasa nke oxygen na elu oxygen, si otú a na-emekọ usoro oxida.
Ngwakọta mmiri dị na mmiri mmiri na-aga ihe dị ka 60G / l, mezie okpomọkụ ahụ ruo ihe dị ka 80 ℃, na-ewebata nrụgide na 0.4MPa, na oxidize maka 1 awa. Oxingdị oxidation ọnụego nke cerium nwere ike iru 95%. Na Production Mepụta, akụrụngwa nke alkali na-enweta site na alkali site na Alkali site na ọdịda nke sodium sọọsọ dị mgbagwoju anya. Iji melata usoro ahụ, ọdịda sodium na-adịkarị mgbagwoju anya nnu na ihe ngwọta alkaline nwere ike ịgbakwunye na tankị oxidation oxidation, na-enwe nrụgide na ọnọdụ okpomọkụ. Enwere ike webata ikuku ikuku ma ọ bụ oxygen iji gbanwee oke mmiri na-enweghị atụ n'ime nnu dị mgbagwoju anya ụwa hydrexides, Oh (oh) 3 n'ime OP (Oh) 4.
N'okpuru ọnọdụ mgbasa ozi, agwọ na alkali dị mgbagwoju anya nnu dị mgbagwoju anya, oxidation ọnụego nke cearrium, na-eme ka ọ dị mma karịa. Mgbe nkeji iri anọ na ise nke mmeghachi omume, ntụgharị nke okpukpu abụọ nnu nnu na ọnụego oxidara nke certium ruru 96%.
