Inta lagu guda jiro habka wax soo saarka maalinlaha ah, sababtoo ah gabowga ee foornada sintering, koronto dhaliyaha nitrogen, ammonia dumis iyo qalab kale, alaabta birta ah budada foornada ka dib waxay leeyihiin taxane ah dhibaatooyin oksaydhism sida madow, jaalle ah, decarburization, iyo ciid qarxinta dusha sare. ee alaabta.

Ka dib marka dhibaatadu dhacdo, soo-saaruhu waa inuu baaro jawiga ilaalinta sida ugu dhakhsaha badan.Alaabta kormeerka guud ahaan waxaa ka mid ah in dayactirka joogtada ah ee dhaliiyaha nitrogen-ka si caadi ah loo fuliyo, heerka shaqo ee dhaliiyaha nitrogen-ka, iyo haddii qiyamka koronto-dhaliyaha nitrogen P860 ay yihiin kuwo sax ah.Haddii cadaadiska shaqada ee munaaradda adsorption ee koronto dhaliyaha nitrogen uu ka hooseeyo xariiqda caadiga ah, haddii heerkulka deoxygenation ee kicinta palladium ee qaybta hydrogenation iyo deoxygenation ay ka baxsan tahay qiyaasta caadiga ah, haddii nadiifinta nitrogen iyo qaybta qalajinta si caadi ah loo kululeeyo, iyo in kale. Maaddada oksijiinta iyo qoyaanka nitrogen ee dhamaadka dambe ee nadiifinta nitrogen ayaa ah tilmaamayaasha haddii ay ku jirto inta u dhaxaysa qiimaha caadiga ah, waa lagama maarmaan in la qaato jawaab-celin waqtigeeda ah dhibaatooyinka kala duwan.

Alaabta birta ah ee budada ah waxay inta badan isticmaalaan suunka mesh foornada si joogto ah u tirtirta waxayna ku riixaan foornada buqaha ee usha si ay u gooyaan.Jawiga ilaalinta waxaa loo kala qaybiyaa badeecooyin naxaas ku salaysan iyo alaabada birta ku salaysan iyadoo loo eegayo alaabta alaabta birta budada ah.Caadi ahaan, budada birta ah ayaa lagu cadaadiyaa si ay u sameyso alaabada ugu badan ee sintered, iyo birta ku salaysan Wixii alaabta birta budada ah, nitrogen-nadiifinta sare leh oo leh biyo ka yar 5PPM iyo nadiif sare 99.999 oo ay soo saarto ammonia kala-soocidda qalabka hydrogen koronto dhaliyaha nitrogen ee goobta PSA iyo hydrogenation iyo nadiifinta deoxygenation ayaa loo isticmaali karaa jawi ilaalin ah.Ka dib markii qaar ka mid ah dhibaatooyinka oksaydhisku ay ku dhacaan alaabada birta budada ah, hubi in koronto-dhaliyaha nitrogen-ka iyo foornada kala-baxa ammonia ay dhammaantood yihiin kuwo caadi ah, ama ka dib marka la xalliyo cillad-soo-saarka nitrogen-ka iyo kala-goynta ammonia, dhibaatada oksaydhka ee alaabta birta budada ah ayaa weli jirta.

Tallaabada xigta waa in ay tixgelisaa foornada sintering lafteeda.

Hadday tahay foornada ul riixa ama foornada suunka mesh, waxaa jiri doona aagga qaboojinta jaakadda biyaha.Ka dib markii tuubada maan-gaabka ee foornada qallafsan ay duug noqoto, waxaa jiri doona daadinta biyaha.Biyuhu waxa ay u dami doonaan ogsijiin heerkul sarreeya, taas oo keenaysa in alaabta birta ah ee budada ahi ay noqoto madow iyo jaalle oo ay kaarboonaysiiso.Ding Wentao, haddii uu ku gubo kulayl sare iyo olol.Ololka waxaa sababa gubashada hydrogen iyo qaybaha birta ah ee budada ee foornada qallafsan.Waqtigan xaadirka ah, walxaha carrada leh ayaa laga soo saari doonaa dusha sare ee alaabta, kuwaas oo ah haraaga gubashada.Haddii daboolka ilaalinta loo isticmaalo in lagu daboolo, waa la hagaajin doonaa, laakiin ilaalinta nitrogen-nadiifinta sare ee aan meesha ku jirin waxay keenaysaa oksaydh yar.

Si kastaba ha ahaatee, alaabta birta ah ee budada ah ee ku salaysan naxaasta, kaliya 75% hydrogen + 25 nitrogen gaaska isku dhafan ee ay soo saarto ammonia si ay u soo saarto hydrogen ayaa loo isticmaali karaa jawiga ilaalinta.Dabcan, isticmaalka hydrogen-nadiifinta sare waa mid waxtar badan leh, sababtoo ah qiimaha gaaska weyn iyo badbaadada hawlgalka.Intooda badan waxay adeegsadaan aaladaha soo saarista haydaroojin ee kala furfura ammonia sida isha hydrogen.

Marka tuubada muffle-ga ee foornada qallafsan ay soo daato oo ay gubato, wax soo saarka tuubada maan-dhaafka waa in isla markiiba la joojiyaa oo la beddelaa.Si aanay u saamayn tayada alaabta!
