Ividiyo
Ukukhiqizwa kwe-hydrogen kusuka kugesi yemvelo ukwenza ukusabela kwamakhemikhali kwegesi yemvelo ecindezelwe nencibilikisiwe kanye nesimusi endaweni ekhethekile egcwalisa i-catalyst futhi ikhiqize igesi yokulungisa nge-H₂, CO₂ ne-CO, iguqule i-CO kumagesi aguqulayo abe yi-CO₂ bese ukhipha. i-H₂ efanelekile kusuka kumagesi aguqukayo nge-pressure swing adsorption (PSA).
Idizayini Yokukhiqiza I-Hydrogen kanye nemiphumela yokukhethwa kwemishini evela ezifundweni ezibanzi zobunjiniyela be-TCWY nokuhlola abathengisi, ngokwenza kahle kakhulu lokhu okulandelayo:
1. Ukuphepha nokusebenza Kalula
2. Ukwethembeka
3. Ukulethwa kwemishini emifushane
4. Umsebenzi omncane wasensimini
5. Imali yokuncintisana nezindleko zokusebenza
(1) Ukuchithwa Kwegesi Yemvelo
Ezingeni elithile lokushisa nokucindezela, negesi yokuphakelayo ngokusebenzisa i-oxidation ye-manganese ne-zinc oxide adsorbent, isamba sesibabule esisegesini yokudla sizocisha sibe ngaphansi kuka-0.2ppm ngezansi ukuze kuhlangatshezwane nezidingo zama-catalysts zokuguqulwa kwesitimu.
Ukusabela okuyinhloko ukuthi:
| COS+MnO |
| I-MnS+H2O |
| H2S+ZnO |
(2) I-NG Steam Reforming
Inqubo yokuguqula umusi isebenzisa umhwamuko wamanzi njenge-oxidant, futhi nge-nickel catalyst, ama-hydrocarbon azoguqulwa abe igesi eluhlaza ekukhiqizeni igesi ye-hydrogen. Le nqubo iyinqubo ye-endothermic efuna ukunikezwa kokushisa okuvela engxenyeni yemisebe ye-Frnace.
Ukusabela okuyinhloko phambi kwe-nickel catalysts imi kanje:
| CnHm+nH2O = nCO+(n+m/2)H2 |
| CO+H2O = CO2+H2 △H°298= – 41KJ/mol |
| CO+3H2 = CH4+H2O △H°298= – 206KJ/mol |
(3) Ukuhlanzwa kwe-PSA
Njengenqubo yeyunithi yamakhemikhali, ubuchwepheshe bokuhlukaniswa kwegesi ye-PSA buye bathuthuka ngokushesha baba isiyalo esizimele, futhi busetshenziswa kabanzi emikhakheni ye-petrochemical, amakhemikhali, insimbi, i-electronics, ukuvikela kuzwelonke, imithi, imboni elula, ezolimo kanye nokuvikelwa kwemvelo. izimboni, njll. Njengamanje, i-PSA isiphenduke inqubo eyinhloko ka-H2ukuhlukaniswa okuye kwasetshenziselwa ngempumelelo ukuhlanzwa nokuhlukaniswa kwe-carbon dioxide, i-carbon monoxide, i-nitrogen, i-oxygen, i-methane namanye amagesi ezimboni.
Ucwaningo luthola ukuthi ezinye izinto eziqinile ezinokwakheka okuhle kwezimbotshana zingamunca amangqamuzana oketshezi, futhi into emunca kanjalo ibizwa ngokuthi i-absorbent. Lapho ama-molecule e-fluid ethintana nama-adsorbents aqinile, i-adsorption ivela ngokushesha. I-adsorption iphumela ekuhlanganiseni okuhlukene kwama-molecule amuncwe oketshezini nasendaweni emuncayo. Futhi ama-molecule adsorbed yi-absorbent azothuthukiswa phezu kwawo. Njengokuvamile, ama-molecule ahlukene azobonisa izici ezihlukene lapho amuncwa ama-adsorbents. Futhi izimo zangaphandle ezifana nezinga lokushisa loketshezi nokugxila (ingcindezi) zizothinta lokhu ngokuqondile. Ngakho-ke, ngenxa nje yalolu hlobo lwezimpawu ezihlukene, ngokushintsha kwezinga lokushisa noma ingcindezi, singakwazi ukufeza ukuhlukaniswa nokuhlanzwa kwengxube.
Kulesi sitshalo, ama-adsorbent ahlukahlukene agcwaliswa embhedeni we-adsorption. Lapho igesi eshintshayo (ingxube yegesi) igelezela kukholomu ye-adsorption (umbhede we-adsorption) ngaphansi kwengcindezi ethile, ngenxa yezici ezihlukile zokukhanga ze-H.2, CO, CH2, CO2, njll. i-CO, CH2kanye ne-CO2Ama-adsorbents, kuyilapho i-H2izogeleza iphuma phezulu kombhede ukuze ithole i-hydrogen yomkhiqizo ofanelekayo.
