I-alumina esebenzayo yimathiriyeli enamandla kakhulu kunye ne-versatile ephuma kwi-aluminium oxide (Al2O3). Iveliswa ngokuchithwa kwe-aluminium hydroxide, okubangela ukuba i-granular substance kunye nommandla ophezulu kunye neempawu ezigqwesileyo ze-adsorption. Olu luhlu lukhethekileyo lweempawu lwenza i-alumina esebenzayo ibe yinto ebalulekileyo kwizicelo ezahlukeneyo zemizi-mveliso, kubandakanywa nokunyanga amanzi, ukucocwa komoya, kunye nenkxaso ye-catalyst.
Enye yezona zinto zibalulekileyo zokusetyenziswa kwe-alumina esebenzayo kwiinkqubo zokunyanga amanzi. I-porosity yayo ephezulu ivumela ukuba ibhengeze ngokufanelekileyo ukungcola, isinyithi esinzima, kunye nezinye izinto ezingcolileyo emanzini. I-alumina esebenzayo iyasebenza ngokukodwa ekususeni i-fluoride, i-arsenic, kunye ne-selenium, iyenza ibe sisixhobo esixabisekileyo kuluntu olujongene nemiba yobulunga bamanzi. Izinto eziphathekayo zingasetyenziselwa kwiinkqubo zombini ezisisigxina kunye ne-batch, ukubonelela ukuguquguquka kwisicelo sayo. Ngaphezu koko, i-alumina esebenzayo ingaphinda ihlaziywe ngeenkqubo zokuhlamba ezilula, okwenza kube sisisombululo esineendleko zokuhlanjululwa kwamanzi ixesha elide.
Ukongeza kunyango lwamanzi, i-alumina esebenzayo isetyenziswa ngokubanzi kwiinkqubo zokucoca umoya. Ikhono layo lokubhengeza umswakama kunye ne-volatile organic compounds (VOCs) yenza kube yinto efanelekileyo yokukhetha i-desiccants kunye nezihlungi zomoya. I-alumina esebenzayo inokunceda ukulawula amanqanaba okufuma kwiindawo ezahlukeneyo, ukusuka kwimizi-mveliso ukuya kwiindawo zokuhlala. Ngokususa ukufuma okugqithisileyo emoyeni, kuthintela ukukhula kokungunda kunye nokungunda, okunegalelo kumgangatho womoya osempilweni wangaphakathi. Ngapha koko, i-alumina esebenzayo ihlala isetyenziswa kwiinkqubo zokwahlula igesi, apho inceda ukususa ukungcola kwirhasi yendalo kunye nezinye iigesi zamashishini.
Esinye isicelo esibalulekileyo se-alumina esebenzayo njengenkxaso ye-catalyst kwi-chemical reactions. Ummandla wayo ophezulu kunye nokuzinza kwe-thermal kwenza kube yinto ebalaseleyo yokuxhasa i-catalysts kwiinkqubo ezahlukeneyo, kubandakanywa ukucocwa kwe-petrochemical kunye nokuveliswa kweekhemikhali ezikhethekileyo. I-alumina esebenzayo inokuphucula ukusebenza kakuhle kweempendulo ze-catalytic ngokubonelela ngomphezulu ozinzileyo we-catalyst esebenzayo, ngaloo ndlela inyusa isivuno esipheleleyo semveliso efunwayo. Esi sicelo sibaluleke kakhulu kwimveliso yamafutha kunye neekhemikhali, apho ukulungiswa kweemeko zokusabela kunokukhokelela ekugcinweni kweendleko kunye nokunciphisa impembelelo yokusingqongileyo.
Ukuguquguquka kwe-alumina esebenzayo kufikelela ekusetyenzisweni kwayo kumashishini amayeza kunye nokutya ngokunjalo. Kula macandelo, isetyenziselwa ukubhengezwa kokungcola kunye nokucocwa kweemveliso. I-alumina esebenzayo inokunceda ukuqinisekisa ukhuseleko kunye nomgangatho wamachiza kunye neemveliso zokutya ngokususa izinto ezingcolisayo ezinokubeka esichengeni ingqibelelo yazo. Ubume bayo obungenabuthi kunye nokuthotyelwa kokulawula kwenza kube yinto ekhethwayo kwizicelo apho ukucoceka kwemveliso kubaluleke kakhulu.
Ukuqukumbela, i-alumina evuliweyo sisixhobo esisebenza kakhulu kwaye sisebenza ngeendlela ezininzi ezinoluhlu olubanzi lwezicelo kumashishini ahlukeneyo. Iimpawu zayo eziyingqayizivele, ezibandakanya i-porosity ephezulu, i-adsorption egqwesileyo yamandla, kunye nokuzinza kwe-thermal, yenza kube ngumthombo ongenakulinganiswa wokunyanga kwamanzi, ukuhlanjululwa komoya, inkxaso ye-catalyst, kunye nokunye. Njengoko amashishini eqhubeka nokufuna izisombululo ezizinzileyo nezisebenzayo zokuhlangabezana nemingeni yokusingqongileyo kunye nolawulo, imfuno ye-alumina esebenzayo kulindeleke ukuba ikhule. Ikhono layo lokuphucula umgangatho wemveliso kunye nokhuseleko ngelixa lifaka isandla kwizikhundla zokukhusela i-alumina esebenzayo njengomdlali ophambili kwixesha elizayo lezicelo zoshishino.
