I-alumina ecushiwe iwumsebenzi omboza kakhulu futhi oguquguqukayo osuselwe ku-aluminium oxide (Al2O3). Ikhiqizwa ngokuncipha kwamanzi kwe-aluminium hydroxide, okuholela entweni eyimbudumbudu enendawo ephezulu kanye nezakhiwo ezinhle kakhulu zokukhangisa. Le nhlanganisela eyingqayizivele yezici yenza i-alumina ecushiwe ibe yingxenye ebalulekile ekusetshenzisweni kwezimboni ezihlukahlukene, okuhlanganisa ukuhlanzwa kwamanzi, ukuhlanzwa komoya, kanye nokwesekwa kwe-catalyst.
Okunye okubaluleke kakhulu ukusetshenziswa kwe-alumina ecushiwe kusezinqubo zokwelashwa kwamanzi. I-porosity yayo ephezulu ivumela ukuthi ikwazi ukukhangisa ngempumelelo ukungcola, izinsimbi ezisindayo, nokunye ukungcola okuvela emanzini. I-alumina ecushiwe isebenza kahle kakhulu ekususeni i-fluoride, i-arsenic, ne-selenium, iyenze ibe isisetshenziswa esibalulekile semiphakathi ebhekene nezinkinga zekhwalithi yamanzi. Izinto ezisetshenziswayo zingasetshenziswa kukho kokubili umbhede ongaguquki kanye nezinqubo ze-batch, zinikeze ukuguquguquka ekusetshenzisweni kwazo. Ngaphezu kwalokho, i-alumina ecushiwe ingavuselelwa ngezinqubo ezilula zokugeza, okwenza kube yisixazululo esingabizi kakhulu sokuhlanzwa kwamanzi isikhathi eside.
Ngaphezu kokwelashwa kwamanzi, i-alumina ecushiwe isetshenziswa kakhulu ezinhlelweni zokuhlanza umoya. Amandla ayo okukhangisa umswakama kanye nama-organic compounds aguquguqukayo (VOCs) enza kube ukukhetha okuhle kwama-desiccants nezihlungi zomoya. I-alumina ecushiwe ingasiza ukulawula amazinga womswakamo ezindaweni ezihlukahlukene, kusukela kuzilungiselelo zezimboni kuya ezindaweni zokuhlala. Ngokususa umswakama owedlulele emoyeni, kuvimbela ukukhula kwesikhunta nesikhutha, kube nomthelela eqophelweni eliphezulu lomoya wasendlini. Ngaphezu kwalokho, i-alumina ecushiwe ivame ukusetshenziswa ezinqubweni zokuhlukanisa igesi, lapho isiza ukususa ukungcola egesi yemvelo namanye amagesi ezimboni.
Okunye ukusetshenziswa okubalulekile kwe-alumina ecushiwe njengokwesekwa kwe-catalyst ekuphenduleni kwamakhemikhali. Indawo yayo ephezulu kanye nokuzinza kokushisa kuyenza ibe yindawo enhle kakhulu yokusekela ama-catalyst ezinqubweni ezihlukahlukene, okuhlanganisa ukucwengwa kwe-petrochemical kanye nokukhiqizwa kwamakhemikhali akhethekile. I-alumina ecushiwe ingathuthukisa ukusebenza kahle kokusabela kwe-catalytic ngokunikeza indawo ezinzile ye-catalyst esebenzayo, ngaleyo ndlela yandise isivuno somkhiqizo ofunekayo. Lolu hlelo lokusebenza lubaluleke kakhulu ekukhiqizweni kwezibaseli namakhemikhali, lapho ukwenza ngcono izimo zokusabela kungaholela ekongeni kwezindleko kanye nomthelela oncishisiwe kwezemvelo.
Ukuguquguquka kwe-alumina ecushiwe kudlulela nasekusetshenzisweni kwayo ezimbonini zemithi nezokudla futhi. Kule mikhakha, isetshenziselwa ukukhangisa ukungcola kanye nokuhlanzwa kwemikhiqizo. I-alumina ecushiwe ingasiza ukuqinisekisa ukuphepha kanye nekhwalithi yemithi nemikhiqizo yokudla ngokususa ukungcola okungafaka engozini ubuqotho bayo. Ubunjalo bayo obungenabo ubuthi nokuhambisana nomthetho kwenza kube ukukhetha okuncanyelwayo kwezicelo lapho ukuhlanzeka komkhiqizo kubaluleke kakhulu.
Sengiphetha, i-alumina ecushiwe iyinto esebenza kahle kakhulu futhi eguquguqukayo enezinhlobonhlobo zezinhlelo zokusebenza kuzo zonke izimboni ezahlukahlukene. Izakhiwo zayo eziyingqayizivele, ezihlanganisa i-porosity ephezulu, amakhono amahle kakhulu we-adsorption, nokuzinza kwe-thermal, kuyenza ibe umthombo obalulekile wokwelashwa kwamanzi, ukuhlanzwa komoya, ukusekelwa kwe-catalyst, nokuningi. Njengoba izimboni ziqhubeka nokufuna izixazululo ezisimeme nezisebenza kahle zokuhlangabezana nezinselelo zemvelo nezokulawula, isidingo se-alumina ecushiwe kulindeleke ukuthi sikhule. Ikhono layo lokuthuthukisa ikhwalithi yomkhiqizo nokuphepha kuyilapho inikela ezikhundleni zokuvikela indawo ezungezile yenza i-alumina yasebenza njengomdlali oyinhloko esikhathini esizayo sezinhlelo zokusebenza zezimboni.
