i-petrochemicals, amayeza, kunye nokwahlula igesi. Enye yezona zisefu ze-molecular ezisetyenziswa kakhulu yi-XH-7, eyaziwa ngokuba yi-adsorption egqwesileyo kunye nokuzinza okuphezulu kwe-thermal.

XH-7 i-molecular sieveszi-zeolite zokwenziwa eziquka uthungelwano olunamacala amathathu amajelo adityanisiweyo kunye neekheji. Le mijelo inobukhulu obufanayo, evumela iimolekyuli zobukhulu obuthile kuphela ukuba zidlule. Le propati yenza i-XH-7 ibe yinto ekhethekileyo yokukhetha izicelo ze-adsorption ezikhethiweyo, apho inokususa ukungcola okungafunekiyo kumxube.

Ukuzinza okuphezulu kwe-thermal ye-XH-7 yenye inzuzo ebalulekileyo, evumela ukuba ikwazi ukumelana nokushisa okuphezulu ngaphandle kokulahlekelwa iipropati zayo ze-adsorption. Le propati yenza ukuba ilungele izicelo ezifuna ukufudumeza, njengokususwa kwamanzi kwi-solvents eziphilayo.

Enye yezona zinto ziqhelekileyo zokusetyenziswa kwe-XH-7 i-molecular sieves kukuhlanjululwa kwegesi yendalo. I-XH-7 inokususa ukungcola okunjengamanzi, i-sulfur compounds, kunye ne-carbon dioxide, okubangelwa ukucoceka okuphezulu kwegesi yendalo. Oku, kukhokelela ekuphuculweni kokusebenza kokutsha kunye nokunciphisa ukukhutshwa kwezinto ezikhutshwayo.

Kwishishini lamachiza, i-XH-7 isetyenziselwa ukuhlambulula iikhompawundi zeziyobisi kunye nokususa ukungcola. Ubungakanani bayo obufanayo be-pore buvumela i-adsorption ekhethiweyo, iqinisekisa ukuba kuphela i-molecule efunwayo iyabanjwa. Oku kubangela iziyobisi ezicocekileyo ezineziphumo ebezingalindelekanga ezimbalwa.

XH-7 i-molecular sieveszikwasetyenziswa ekuveliseni umoya otyetyisiweyo weoksijini, apho zikhetha ngokukhetha initrogen emoyeni, nto leyo ekhokelela kuxinzelelo oluphezulu lweoksijini. Oku luncedo kwizicelo zonyango apho unyango lwe-oxygen lufunekayo.

Isishwankathelo, i-XH-7 i-molecular sieves iyinxalenye ebalulekileyo kumashishini amaninzi, anikezela ngeempawu ezintle ze-adsorption, ukuzinza okuphezulu kwe-thermal, kunye nobukhulu obufanayo be-pore. Ukusuka ekucoceni igesi yendalo ukuya ekuhlanjululweni kweziyobisi zamachiza, i-XH-7 idlala indima ebalulekileyo ekuqinisekiseni ukucoceka kwemveliso kunye nokusebenza kakuhle.

Xa kuziwa ekukhetheni isisefo esifanelekileyo semolekyuli kwisicelo esithile, kubalulekile ukuqwalasela izinto ezinje ngobungakanani kunye nokumila kweealekyuli eziza kubhengezwa, ubushushu obusebenzayo, kunye nenqanaba elifunekayo lokucoceka.

XH-7 i-molecular sievesbabe nobukhulu bepore obumalunga ne-7 angstroms, ibenza ukuba bafanelekele izicelo apho iimolekyuli zolu bungakanani kufuneka zihlulwe. Kananjalo banommandla ophezulu, ovumela inani elikhulu leendawo ze-adsorption, ezikhokelela ekuphuculeni ukusebenza kakuhle.

Enye inzuzo ye-XH-7 ye-molecular sieves yi-high chemical stability. Bangakwazi ukumelana noluhlu olubanzi lwamaxabiso e-pH kwaye baxhathise ukuthotywa kwe-acids, iziseko, kunye ne-organic solvents, ezenza ukuba zilungele ukusetyenziswa kwiindawo ezinzima.

Ukuqinisekisa ukusebenza kakuhle kwe-XH-7 ye-molecular sieves, kubalulekile ukulandela izikhokelo zomenzi ukuze kusebenze kunye nokuvuselelwa. Ukuqalisa kubandakanya ukususa nabuphi na ubumanzi obukhoyo kwiisefu, ngelixa ukuvuselelwa kwakhona kubandakanya ukususa naziphi na iimolekyuli ze-adsorbed kunye nokubuyisela iimpawu ze-adsorption ze-sieves.

Ukuqukumbela, i-XH-7 ye-molecular sieves ibonelela ngeenzuzo ezininzi ngaphezu kwezinye ii-adsorbents, ezibenza zibe lukhetho oludumileyo kumashishini amaninzi. Ubungakanani bepore obufanayo, ukuzinza okuphezulu kwe-thermal, kunye neepropathi ezigqwesileyo zokubhengeza zibenza balungele ukwahlukana kwezicelo ezikhethiweyo. Ngokukhetha i-molecular sieve efanelekileyo kwisicelo esithile kunye nokulandela izikhokelo zomenzi ukuze kusebenze kunye nokuvuselelwa, abasebenzisi banokuqinisekisa ukusebenza kakuhle kunye nokusebenza kakuhle.
