Ngomhla wama-30 ku-Epreli, ngo-2026 – Imarike ye-alumina esebenzayo kwihlabathi liphela ibone ukukhula okuqinileyo ngo-2025, ixabiso layo lilonke lifikelela kwi-USD 1.19 yeebhiliyoni, ngokutsho kwengxelo yamva nje ekhutshwe yiDatam Intelligence 4 Market Research LLP. Iingqikelelo zibonisa ukuba imakethi iya kuqhubeka nokukhula kwayo okuzinzileyo, ikhula ngesantya sokukhula sonyaka esidibeneyo (CAGR) se-5.9% ukusuka ngo-2025 ukuya ku-2033 kwaye ifikelele kwi-USD 1.87 yeebhiliyoni ekupheleni kwexesha eliqikelelweyo. Olu kukhula luphawulekayo lukhuthazwa kakhulu yimithetho engqongqo yokusingqongileyo kwihlabathi liphela, ukwanda ngokukhawuleza kweshishini elitsha lamandla, kunye nokwamkelwa okwandayo kwe-alumina esebenzayo kwizicelo ezahlukeneyo zoshishino, ukusuka kunyango lwamanzi ukuya kwinkxaso ye-catalyst kunye nokucocwa kwegesi.
I-alumina esebenzayo, uhlobo lwe-aluminium oxide (Al₂O₃) olunemingxuma emininzi oluveliswa yi-dehydroxylating aluminium hydroxide, idume ngomthamo wayo obalaseleyo wokufunxa, indawo ephezulu (ngesiqhelo ukusuka kwi-200 ukuya kwi-400 m²/g), kunye nokuzinza kobushushu. Ezi mpawu zikhethekileyo ziyenza ibe yinto eyimfuneko kumacandelo amaninzi, apho unyango lwamanzi, iikhemikhali zepetroli, kunye namandla amatsha avela njengezinto eziphambili ezibangela imfuno yemarike kwiminyaka yakutshanje.
Kwicandelo lokunyanga amanzi, ukuphunyezwa kwemigangatho engqongqo yokusingqongileyo kube yinto ephambili ekukhuleni kwemarike. Oorhulumente kwihlabathi liphela baqinisa imithetho ukuqinisekisa ukufikelela emanzini okusela akhuselekileyo, kunye ne-World Health Organisation (WHO) eqikelela ukuba malunga ne-2 yeebhiliyoni zabantu kwihlabathi liphela abasakwazi ukufikelela emanzini okusela acocekileyo. I-alumina esebenzayo isetyenziswa kakhulu kwiinkqubo zokucoca amanzi ukususa i-fluoride, i-arsenic, kunye nezinye izinto ezingcolisayo eziyingozi, ngenxa yokukwazi kwayo ukunciphisa amanqanaba e-fluoride ukusuka kwi-10 ppm ukuya ngaphantsi kwe-1 ppm phantsi kweemeko ezifanelekileyo. ETshayina, ukuphunyezwa koMgangatho oHlaziyiweyo we-"Drinking Water Hygiene Standard" (GB 5749–2022) kuye kwanyusa kakhulu imfuno yeemveliso ze-alumina ezisebenzayo eziphezulu ezinomphezulu ophezulu (≥380 m²/g), umthamo omkhulu we-pore (≥0.45 cm³/g), kunye nomxholo wokungcola ophantsi (Fe₂O₃ ≤0.02%), kunye nezinga lokungena kweemodeli eziphezulu kwizityalo zamanzi zikamasipala lifikelela kwi-71.3% ngo-2024.
Ishishini elitsha lamandla, ingakumbi icandelo leebhetri ze-lithium-ion, livele njengomqhubi okhula kakhulu kwimarike ye-alumina esebenzayo. Njengoko ukutyhalela phambili kwehlabathi kwizisombululo zamandla ezizinzileyo kusanda, imfuno yezithuthi zombane (ii-EV) kunye neenkqubo zokugcina amandla iye yanda, nto leyo eqhuba imfuneko ye-alumina esebenzayo enobunyulu obuphezulu ekuvelisweni kwebhetri. I-alumina esebenzayo isetyenziswa njengesithambisi somswakama kwiibhetri ze-lithium-ion, ithintela ukuwohloka okubangelwa kukufuma kunye nokungcola kwaye iqinisekisa ukusebenza kakuhle kwebhetri kunye nobomi obude. Ngo-2024, imfuno ye-alumina esebenzayo kwizicelo zokugquma ze-lithium battery separator eTshayina idlule kwiitoni ezingama-21,000, nge-CAGR engama-37.6% ukusuka ngo-2020 ukuya ku-2024, kwaye umda wenzuzo iyonke yale candelo wahlala phakathi kwama-35% nama-42%, aphezulu kakhulu kunalawo ezicelo zemveli.
Amashishini e-petrochemical kunye ne-refinery ayaqhubeka nokuba ngabathengi abakhulu be-activated alumina, apho isetyenziswa kakhulu njenge-catalyst support kunye ne-desiccant. Ngokwandiswa kwezixhobo ze-炼化 kwihlabathi liphela kunye nokuphuculwa kweenkqubo ze-煤化工, imfuno ye-activated alumina enamandla aphezulu oomatshini (≥150 N/cm) kunye nolawulo oluchanekileyo lobukhulu be-pore (8–15 nm) iqhubekile nokunyuka. Ngo-2024, ukusetyenziswa kwe-activated alumina kwizicelo ze-catalyst carrier kwafikelela kwiitoni ezili-128,000, kunye nenani leemveliso eziphezulu linyuka ukuya kwi-58%.
Iinguqu ezinkulu kwimarike yengingqi zibonisa umahluko omkhulu, apho i-Asia-Pacific iphuma njengemarike ebalaseleyo ngenxa yokwanda ngokukhawuleza kwemizi-mveliso, imithetho engqongqo yokusingqongileyo, kunye nokubakho kweendawo ezinkulu zokwenza imveliso. I-China, ngokukodwa, ibe ngumdlali ophambili kwimarike yehlabathi ye-alumina esebenzayo, kunye nomthamo wayo wonke wemveliso ofikelela kwi-1.68 yezigidi zeetoni ngo-2024, apho ngaphezulu kwe-60% yamandla amatsha yayiziimveliso ezikhethekileyo eziphezulu. Amashishini aphambili aseTshayina, kuquka i-Aluminium Corporation yaseTshayina (Chinalco), i-Sinocera Material Co., Ltd., kunye ne-Shandong Dongyue Group, akhawulezisa utshintsho lwawo olucwangcisiweyo, esebenzisa izixhobo zamandla emvula eMzantsi-ntshona weTshayina kunye neemodeli zoqoqosho olujikelezayo ukwakha iziseko zemveliso eluhlaza kunye nekhabhoni ephantsi. Umzekelo, iprojekthi ye-alumina eluhlaza esebenza ye-Chinalco ye-100,000-ton/ngonyaka eYunnan, eyafakwa kwimveliso ngo-2024, inokusetyenziswa kwamandla okupheleleyo ngemveliso nganye ngeyunithi nge-18% ngaphantsi komndilili weshishini.
UMntla Melika ukulungele uphuhliso lwemarike ngokukhawuleza, oluqhutywa yimithetho engqongqo yokusingqongileyo malunga nokucocwa kwamanzi kunye nokukhutshwa kwemveliso, kunye notyalo-mali olukhulu kuphuhliso lwetekhnoloji. Uphuhliso lwakutshanje lweshishini eMelika lubandakanya ukuthengwa komvelisi we-adsorbent osekwe e-US yinkampani yeekhemikhali ezikhethekileyo zehlabathi ngoJanuwari 2026, ejolise ekwandiseni ipotifoliyo yayo yemveliso ye-alumina esebenzayo kunye nokuqinisa isikhundla sayo kwiimarike zokusingqongileyo namandla. NgoJuni 2025, iHindalco Industries yagqiba ukuthengwa kwe-Aluchem Companies Inc. ese-US ukuze yandise i-alumina yayo ekhethekileyo kunye ne-alumina esebenzayo kunye nokufikelela kubuchwepheshe bokucubungula obuphambili.
Nangona kukho indlela entle yokukhula, imakethi ye-alumina esebenzayo ijongene nemingeni eliqela, kuquka ukuguquguquka kwamaxabiso ezinto eziluhlaza kunye nosongelo lwezinto ezizezinye ezifana nee-molecular sieves. Izinto eziphambili ze-alumina ezisebenzayo yi-aluminium hydroxide yemizi-mveliso, ixabiso layo lichaphazeleka ziindlela zemarike ye-alumina iyonke. Phakathi kowama-2021 nowama-2023, iingxaki zamandla zehlabathi kunye nemida yemveliso ye-aluminium ye-electrolytic yasekhaya ikhokelele ekunyukeni kokunyuka kwamaxabiso e-alumina, efikelela kwi-3,800 yuan/ton (idatha ye-SMM), nto leyo eyonyuse iindleko zemveliso kubavelisi. Ukujongana noku, amanye amashishini aguqukele ekukhupheni i-aluminium hydroxide kwinkunkuma eqinileyo yemizi-mveliso efana nodaka olubomvu, olungagcini nje ngokunciphisa ukuxhomekeka kwezinto eziluhlaza kodwa luhambelana nemeko yoqoqosho olujikelezayo. Okwangoku, iiprojekthi zokubonisa eGuizhou naseGuangxi zifikelele kumthamo wonyango lodaka olubomvu wonyaka ongaphezulu kweetoni ezingama-500,000, ngokungathanga ngqo zikhupha malunga neetoni ezingama-30,000 zamandla e-alumina asebenzayo.
Ukujonga phambili, imakethi yehlabathi ye-alumina esebenzayo kulindeleke ukuba ibone ukukhula okuqhubekayo, iqhutywa yimfuno ekhulayo evela kwizicelo ezintsha ezifana nokucocwa kwe-hydrogen kunye nokubanjwa kunye nokugcinwa kwekhabhoni (CCS). Njengoko ihlabathi litshintshela kwimithombo yamandla ecocekileyo, i-alumina esebenzayo ibonakalisa ukuba ibaluleke kakhulu kwishishini lemveliso ye-hydrogen, apho isetyenziselwa ukususa umswakama kunye neekhompawundi zesalfure kwi-hydrogen eveliswa ngokuguqulwa kwe-steam methane (SMR), ukuqinisekisa ubunyulu obufunekayo kwiiseli zamafutha ezisebenzayo. Kwicandelo le-CCS, i-alumina esebenzayo iphononongwa amandla ayo okubamba nokugcina i-carbon dioxide, yandisa ngakumbi ububanzi bokusetyenziswa kwayo.
Iingcali zoshishino ziqikelela ukuba imeko yokhuphiswano lwemarike ye-alumina esebenzayo iya kuqhubeka nokukhula, kunye namashishini agxile ekuveliseni izinto ezintsha zobuchwepheshe, ukwenza ngokwezifiso iimveliso, kunye nokuvelisa izinto eziluhlaza ukuze afumane ithuba lokukhuphisana. Utshintsho oluvela kukhuphiswano olujolise kwisikali ukuya kukhuphiswano olujolise kwixabiso kulindeleke ukuba lukhawuleze, kunye neemveliso ezikhethekileyo eziphezulu ezibalelwa ngaphezulu kwe-45% yemveliso iyonke ngo-2027. “Amashishini anezakhono zokuvelisa izinto eziluhlaza, ulwakhiwo lwentsebenziswano yengingqi, kunye nolawulo lwetekhnoloji olucwangcisiweyo aya kulawula amathuba okwakha kwimarike,” utshilo umhlalutyi weshishini ovela kwiDatam Intelligence. “Ishishini le-alumina esebenzayo lisecaleni kwesigaba esitsha sophuhliso olusemgangathweni ophezulu, oluqhutywa kukukhuselwa kwendalo, amandla amatsha, kunye nokuvelisa izinto ezintsha zobuchwepheshe.”
