Isoko rya alumina ku isi ririmo guhinduka mu mwaka wa 2026, riterwa n’iterambere ry’ikoranabuhanga mu ngufu za hydrogen, imbaraga nyinshi zo gukomeza inganda, n’ubukene bukomeye bw’urwego rutunganya amazi. Abasesenguzi b’inganda bateganya ko isoko rizagera kuri miliyari 1.29 z’amadolari y’Amerika na miliyari 1.3 z’amadolari y’Amerika mu 2026, aho hateganijwe ko hazabaho iterambere rikomeye mu myaka icumi iri imbere.
Iterambere rya siyansi ryatumye habaho ubushobozi bwa hydrogène
Mu iterambere rikomeye ku rwego rw'ingufu zisukuye, ubushakashatsi bushya bwasohotse muri Fuel bwagaragaje uburyo bw'ingenzi alumina ikora ishobora guhindura uburyo ikorwa rya hydrogen. Itsinda ry'abashakashatsi ryagaragaje ko guhindura ubuso bwa aluminium hakoreshejwe urwego rwa nanometer ifite imyenge γ-Al₂O₃ (alumina ikora) bitera "impinduka ikomeye yo kumena." Ubu buryo buhindura ubuso bwa aluminium busanzwe bumeze nk'amazi bugahinduka hydrophilic, bikihutisha cyane imikorere hagati ya aluminium n'amazi kugira ngo hakorwe hydrogen.
Ubu buvumbuzi bukemura ikibazo kimaze igihe kinini cyo gukoresha aluminiyumu nk'umuyoboro w'amazi wa hydrogen ucucitse kandi wizewe. Mu kugabanya cyane igihe cyo gutangira gukora no kugabanya gufatana kw'utubumbe twa hydrogen, ibikoresho byahinduwe bishobora gutuma aluminiyumu iba isoko ya hydrogen ikenewe, ikoreshwa mu gutwara lisansi. Abanditsi bavuze bati: "Ubu bushakashatsi butanga uburyo bushya n'inzira yo gukoresha Al mu gukora hydrogen," bagaragaza uruhare rw'ibikoresho mu gutsinda filime ya oxide idakora ikunze gutuma aluminium itagira umwuka mu mazi adafite umwuka.
Icyiciro cy'ibanze cyo kuvugurura no kubungabunga ibintu birambye
Bijyanye no gukoresha ingufu, inganda zirimo gutera intambwe mu bukungu bushingiye ku mikorere. Abashakashatsi bagaragaje neza uburyo bwo kongera gukoresha alumina ikoreshwa mu myanda ya aluminiyumu ikomoka mu nganda. Ubu buryo bwo gukoresha ubushyuhe bugenzurwa mu byiciro butanga inzira yo guhindura imyanda y’inganda idafite akamaro kanini, ikaba ibicuruzwa bifite agaciro gakomeye, haba mu gukemura ibibazo by’ibidukikije ndetse n’ikiguzi cy’ibikoresho fatizo.
Iyi gahunda yo kwibanda ku kubungabunga ibidukikije ije mu gihe abacuruzi bakomeye ku isoko nka BASF SE, Honeywell International, Inc., na Sumitomo Chemical Co., Ltd. bakomeje guhanga udushya. Urugero, Sumitomo Chemical irimo gukoresha umusaruro wayo wemewe na ISO9001 kugira ngo itange alumina ifite isuku nyinshi n'ifu ihagije mu bikorwa by'ingenzi kuva kuri peteroli kugeza ku miti.
Imiterere y'Isoko n'Impinduka mu bya Politiki
Dukurikije amakuru y’isoko, uru rwego ruteganijwe kwiyongera ku gipimo cy’izamuka ry’amazi ku mwaka (CAGR) kingana na 5.5% kugeza kuri 5.8% kugeza mu 2036, bikaba bishobora kugera kuri miliyari 2.22 z’amadolari y’Amerika. Ishami rishinzwe gutunganya amazi rikomeje kwiganza, bitewe n’amategeko akaze agenga ibidukikije ndetse n’igikenewe cyihutirwa cyo gukuraho imyanda nka fluoride na arsenic mu mazi yo kunywa, cyane cyane mu turere nka Aziya na Pasifika aho umwanda wo mu mazi yo munsi y’ubutaka ukabije.
Ariko kandi, isoko ririmo kumenyera imiterere mishya y’ubucuruzi. Imisoro ya Amerika yo mu 2025 ku bikoresho bitumizwa mu mahanga yatumye habaho isuzuma rishya ry’imiyoboro y’ibicuruzwa. Abayobozi b’inganda barimo gukoresha ingamba zo kugabanya igiciro, bashora imari mu kongera kuvugurura ibicuruzwa, kandi bakongeraho amasezerano kugira ngo habeho ingingo zigena igiciro kugira ngo bigabanye ihindagurika ry’ibiciro.
Ishoramari rikomeye mu bikorwa remezo muri Afurika
Mu gikorwa cy’ingenzi ku mugabane wa Afurika, Guverinoma y’Igihugu ya Nijeriya n’Ikigo cy’Imari cya Afurika (AFC) bashyize umukono ku masezerano y’ubwumvikane (MoU) ya miliyari 1.3 z’amadolari muri Werurwe 2026. Nubwo byibanze ku ruganda rutunganya alumina, aya masezerano agaragaza icyizere gikomeye mu ruhererekane rw’agaciro rw’amabuye y’agaciro rwo mu karere. Uyu mushinga, witezweho gutanga miliyari 1.2 z’amadolari buri mwaka ku musaruro rusange wa Nijeriya, uzakomeza gutanga ibikoresho fatizo by’ingenzi mu gukora alumina yo mu rwego rwo hejuru izakoreshwa mu nganda no mu bidukikije mu karere kose.
Uko isi irushaho kwibanda ku mazi meza, ingufu zisukuye, n'ibikorwa by'inganda birambye, alumina irimo gukomeza umwanya wayo atari nk'ikinyabutabire cy'ibicuruzwa gusa, ahubwo nk'ikintu cy'ingenzi mu kinyejana cya 21.
