Ujeeddo: Shaleefo molecular Kaarboon waa xayeysiis cusub oo la sameeyay 1970-meeyadii, waa walxo kaarboon ah oo aan dabaylaha ahayn, Kaarboon Molecular Sieves (CMS) oo loo isticmaalo in lagu kala saaro nitrogen-ka kobcinta hawada, iyadoo la adeegsanayo heerkulka qolka cadaadiska hooseeya habka nitrogen, marka loo eego qabow dhaqameed qoto dheer oo sarreeya. Nidaamka nitrogen cadaadisku wuxuu leeyahay kharashyo maalgashi oo yar, Xawaaraha wax soo saarka nitrogen ee sarreeya iyo kharashka nitrogen yar. Sidaa darteed, waa adsorption ee warshadaha ee injineernimada ee doorbiday cadaadiska lulid (PSA) hawada kala soocidda nitrogen adsorbent qani, nitrogen this waxaa si ballaaran loo isticmaalaa in warshadaha kiimikada, warshadaha saliidda iyo gaaska, warshadaha elektarooniga ah, warshadaha cuntada, warshadaha dhuxusha, warshadaha dawooyinka, warshadaha cable, biraha daaweynta kulaylka, gaadiidka iyo kaydinta iyo dhinacyo kale.

Mabda'a shaqada: shaandho molecular kaarboon waa isticmaalka sifooyinka baadhista si loo gaaro kala soocida ogsijiinta iyo nitrogen. In adsorption shaandho molecular ee gaaska nijaasta ah, waaweyn iyo mesoporous oo kaliya ka ciyaara doorka channel, la adsorbed doonaa molecules loo qaado si micropores iyo submicropores, micropores iyo submicropores waa mugga dhabta ah ee adsorption. Sida ku cad jaantuskii hore, shaandhada molecular carbon waxaa ku jira tiro badan oo micropores ah, kuwaas oo u oggolaanaya molecules leh cabbir yar oo kinetic ah inay si degdeg ah ugu faafaan daloollada, iyada oo xaddidaysa gelitaanka molecules dhexroorka weyn. Sababtoo ah farqiga u dhexeeya heerka faafinta qaraabada ee molecules gaaska ee cabbirrada kala duwan, qaybaha isku dhafka gaaska ayaa si wax ku ool ah loo kala saari karaa. Sidaa darteed, qaybinta micropores ee shaandhada molecular kaarboon waa inay u dhaxaysaa 0.28 nm ilaa 0.38nm iyadoo loo eegayo cabbirka molecule-ka. Dhexdhexaadinta cabbirka micropore, ogsijiinta waxay si dhakhso ah ugu faafi kartaa daloolka iyada oo loo marayo daloollada daloolka, laakiin nitrogen waa ay adag tahay in la dhex maro godka daloolka, si loo gaaro kala-soocidda oksijiinta iyo nitrogen. Cabbirka daloolka Micropore waa saldhigga kala-soocidda shaandho molecular carbon ee oksijiinta iyo nitrogen, haddii cabbirka daloolka uu aad u weyn yahay, oksijiinta iyo nitrogen waa sahlan tahay in la galo micropore-ka shaandhada molecular, sidoo kale ma ciyaari karo doorka kala-soocidda; Cabbirka daloolka waa mid aad u yar, oksijiin, nitrogen ma geli karo micropore, sidoo kale ma ciyaari karo doorka kala-goynta.

Kaarboon molecular shaandho hawo kala soocida aaladda nitrogen: aaladda waxaa guud ahaan loo yaqaan mashiinka nitrogen. Habka teknoolojigu waa habka adsorption lulid cadaadiska (habka PSA ee gaaban) heerkulka caadiga ah. Adsorption lulid cadaadisku waa habsocod iyo kala saarid aan lahayn il kulayl. Awoodda adsorption ee shaandhada molecular kaarboon ee qaybaha la isku dhejiyay (badanaa molecules oxygen) ayaa lagu dhajiyaa inta lagu jiro cadaadiska iyo soosaarka gaaska sababtoo ah mabda'a kor ku xusan, iyo desorption inta lagu jiro niyad-jabka iyo qiiqa, si dib loogu soo celiyo shaandhada molecular carbon. Isla mar ahaantaana, nitrogen ee lagu hodmay wejiga gaaska sariirta ayaa sariirta sii mara si ay u noqdaan gaaska alaabta, iyo tillaabo kasta waa hawlgal wareeg ah. Hawlgalka meertada ah ee habka PSA waxaa ka mid ah: ku dallacaadda cadaadiska iyo soosaarka gaaska; Cadaadis isku mid ah; Hoos-u-dhac, daal; Kadib cadaadis, wax soo saarka gaaska; Dhowr marxaladood oo shaqo, samaynta hannaan hawlgal meerto ah. Marka loo eego hababka dib-u-soo-nooleynta ee kala duwan ee geeddi-socodka, waxaa loo qaybin karaa habka dib-u-soo-nooleynta vacuum iyo habka dib-u-soo-kabashada hawada. Qalabka mashiinka samaynta nitrogen ee PSA marka loo eego baahida isticmaaleyaasha waxaa ka mid noqon kara nidaamka nadiifinta hawada cadaadiska, nidaamka xakamaynta barnaamijka valve (dib u soo kabashada faakuumku sidoo kale wuxuu u baahan yahay inuu yeesho bamka faakuumka), iyo nidaamka sahayda nitrogen.
