I-Zeolite ye-molecular sieves idlala indima ebalulekileyo kwi-PSA (i-Pressure Swing Adsorption) inkqubo yokuvelisa i-hydrogen, kunye neempawu zabo zokukhangisa ezikhethiweyo zingundoqo ekufezekiseni ukucocwa kwe-hydrogen ngokufanelekileyo. Imveliso ye-PSA ye-hydrogen yinkqubo ye-adsorption ebonakalayo, yinkqubo yokwahlula igesi esebenzisa amandla ahlukeneyo e-adsorption yeegesi ezahlukeneyo kwi-molecular sieve adsorbent.
Injani Inkqubo yokuCocwa kweHydrojeni?
Njengoko i-hydrogen isetyenziswa kumacandelo amaninzi emizi-mveliso namandla, ngakumbi kwiiseli zepetroli nakwishishini lombane, zineemfuno ezingqongqo ngokugqithisileyo, kuphela i-hydrogen ecocekileyo enokuhlangabezana nezi mfuno.
Kodwa i-hydrogen eveliswa kwizinto eziluhlaza ihlala iqulethe umphunga wamanzi kunye nokungcola okufana ne-carbon monoxide, i-carbon dioxide, i-methane, igesi ye-nitrogen kunye ne-sulfides. La manzi kunye nokungcola kunokutyhefa izinto ezibangela ukuba kwenzeke, ukunciphisa ukusebenza kakuhle kokusabela, ukugqwala kwezixhobo, kwaye kubeke imingcipheko yokhuseleko. Ke ngoko, iinkqubo ezinxulumene nokucocwa kwe-hydrogen zijolise ikakhulu ekomisweni nasekususweni kokungcola.
PSA Imveliso yeHydrojeni kunye nokuCoca
Imveliso ye-hydrogen ye-PSA yenye yezona nkqubo zixhaphakileyo zokucoca i-hydrogen kushishino. Ilungele ukucocwa i-hydrogen{1}equlathe iigesi ezixutyiweyo ezifana negesi ye-oven ye-coke kunye ne-syngas (uhlaziyo lwegesi yendalo, igesi yamalahle).
I-PSA ye-hydrogen yokucocwa isebenzisa amandla okukhetha okukhethayo adsorption kwiisefu zemolekyuli phantsi koxinzelelo oluphezulu, ukwahlula i-hydrogen kwirhasi exutyiweyo. Ubungakanani obufanayo bepore yeesefu zemolekyuli buvumela ukuba babambe iimolekyuli ezincinci zokungcola, kwaye bakhuphe iimolekyuli ezinkulu zehydrogen.
Lo bungakanani{{0}indlela yokukhupha iqinisekisa ukususwa okusebenzayo kwamanzi kunye nokungcola, ivelisa i-ultra-i-hydrogen esulungekileyo efanelekileyo kwizicelo ezibalulekileyo. Kwaye iisefu ze-molecular zeolite ziye zaba sisiseko kule nkqubo.
Ngaphantsi koxinzelelo oluphezulu, ukungcola kuyabhengezwa, ngelixa i-hydrogen idlula. Ngaphantsi koxinzelelo oluphantsi / i-vacuum, i-molecular sieves desorb (ukuvuselela), ukukhulula ukungcola. Ngokutshintsha rhoqo uxinzelelo, ukucoceka okuphezulu kwe-hydrogen kunokufunyanwa ngokuqhubekayo.
Izihlunu zeMolekyuli zokuCocwa kweHydrogen
Inlet air pre{0}}unyango: Phambi kokuba umjelo werhasi oxutyiweyo (oqulathe ihydrogen, umphunga wamanzi, carbon monoxide, carbon dioxide, methane, nitrogen gas, njalo njalo.) ungene kwinkqubo yePSA, uhlobo 3A okanye 4A zeolite zeolite iisefu zemolekyuli (okanye ialumina esebenzayo) kufuneka kususwe amanzi kuqala.
I-adsorption yoxinzelelo oluphezulu: Ukungcola (okufana ne-carbon monoxide, i-carbon dioxide, i-methane, igesi ye-nitrogen, njl.) inokubhengezwa ngohlobo lwe-5A zeolite ze-molecular sieves, kwaye ngamanye amaxesha uthayiphe i-13X zeolite ze-molecular sieves nazo zingasetyenziswa ngokudibeneyo.
