Izisefo ze-molecular ze-Zeolite zidlala indima ebalulekile kunqubo yokukhiqiza i-hydrogen ye-PSA (Pressure Swing Adsorption), futhi izici zazo ezikhethiwe zokukhangisa ziwukhiye wokuzuza ukuhlanzwa kwe-hydrogen okusebenzayo. Ukukhiqizwa kwe-hydrogen ye-PSA kuyinqubo ye-adsorption ebonakalayo, inqubo yokuhlukanisa igesi esebenzisa amandla ahlukene okukhangisa amagesi ahlukene ku-adsorbent ye-molecular sieve.
Injani Inqubo Yokuhlanza I-Hydrogen?
Njengoba i-hydrogen isetshenziswa emikhakheni eminingi yezimboni namandla, ikakhulukazi kumaseli kaphethiloli nasembonini yezogesi, anezidingo eziqine kakhulu, i-hydrogen emsulwa kuphela engahlangabezana nalezi zidingo.
Kodwa i-hydrogen ekhiqizwa ngezinto zokusetshenziswa ngokuvamile iqukethe umhwamuko wamanzi nokungcola okufana ne-carbon monoxide, i-carbon dioxide, i-methane, igesi ye-nitrogen nama-sulfide. Lawa manzi nokungcola kungafaka ushevu ezintweni ezibangela ukusabela, kunciphise ukusebenza kahle, kugceke izinto zokusebenza, futhi kudale izingozi zokuphepha. Ngakho-ke, izinqubo ezihlobene nokuhlanzwa kwe-hydrogen ngokuyinhloko zigxila ekomisweni nasekususeni ukungcola.
I-PSA Hydrogen Production And Purification
I-PSA ukukhiqizwa kwe-hydrogen kungenye yezinqubo ezivame ukusetshenziswa kakhulu zokuhlanza i-hydrogen embonini. Ifaneleka ngokukhethekile ukuhlanza i-hydrogen-equkethe amagesi axubile afana negesi ye-coke oven ne-syngas (ukulungiswa kwegesi yemvelo, ukufakwa kwegesi yamalahle).
I-PSA hydrogen purification isebenzisa amandla akhethekile okukhangisa esisefo samangqamuzana ngaphansi kwengcindezi ephezulu, ukuhlukanisa i-hydrogen negesi exubile. Ubukhulu bezimbotshana obufanayo bezisefo zamangqamuzana buvumela ukuthi babambe ama-molecule amancane okungcola, futhi bakhulule ama-molecule e-hydrogen amakhulu.
Lo sayizi{{0}umshini wokubekela eceleni uqinisekisa ukususwa okusebenzayo kwamanzi nokungcola, ukukhiqiza i-ultra-i-hydrogen ehlanzekile efanele ukusetshenziswa okubalulekile. Futhi izisefo ze-molecular ze-zeolite seziphenduke isisekelo kule nqubo.
Ngaphansi kwengcindezi ephezulu, ukungcola kuyakhangiswa, kuyilapho i-hydrogen idlula. Ngaphansi kwengcindezi ephansi/i-vacuum, izisefo ze-molecular desorb (zenza kabusha), zikhiphe ukungcola. Ngokushintsha ukucindezela ngezikhathi ezithile, i-hydrogen ehlanzekile ingatholakala ngokuqhubekayo.
Izisefo ze-Molecular Zokuhlanza I-Hydrogen
Ukwelashwa kwangaphambili{0}}kokufaka komoya: Ngaphambi kokuthi umfudlana wegesi oxubile (oqukethe i-hydrogen, umhwamuko wamanzi, i-carbon monoxide, i-carbon dioxide, i-methane, igesi ye-nitrogen, njll.) ungene ohlelweni lwe-PSA, thayipha u-3A noma 4A amasefa e-molecular zeolite (noma i-alumina ecushiwe) kudingeka ukuthi kukhishwe amanzi kuqala.
I-adsorption ye-high pressure: Ukungcola (okufana ne-carbon monoxide, i-carbon dioxide, i-methane, igesi ye-nitrogen, njll.) kungakhangiswa ngohlobo 5A lwezisefo ze-molecular zeolite, futhi ngezinye izikhathi thayipha izisefo ze-molecular zeolite ezingu-13X nazo zingasetshenziswa ngokuhlanganiswa.
