Muri iki gihe, ikoreshwa ry’ingenzi rya pseudo-boehmite ni nk'ibikoresho fatizo byo gutegura alumina n'ubukorikori bwo gukora catalyst cyangwa catalyst bigoye. Alumina itegurwa hakoreshejwe pseudo-boehmite ifite ubuso bwihariye kandi ikoreshwa cyane nk'umusemburo n'umusemburo mu nganda za peteroli.
1. ikoreshwa mu bikoresho fatizo bya alumina ya nanometero
Imwe mu MIKORESHEREZE Y'INGENZI YA Pseudo-boehmite ni ibikoresho by'ibanze bya aluminium oxide. Ishingiye ku miterere y'ubuso bunini bwihariye, imikorere myinshi n'ubushobozi bukomeye bwo kwinjiza ibikoresho by'ibanze, yakoreshejwe mu gukora ceramics z'imiterere y'ubushyuhe bwinshi nka aluminium nitride ceramics. Byongeye kandi, nano-Al2O3 ikwiriye cyane cyane mu gutunganya chemical mechanical polishing (CMP), nano-Al2O3 kuko uduce dusya twakozwe na CMP slurry dushobora gukoreshwa mu cyiciro cyo hagati cy'imikorere ya IC nk'ibikoresho bya semiconductor insinga n'ibikoresho bya filime nka tungsten, aluminium, umuringa uhanamye, n'ibirahure bya optique byateye imbere, kristale ya quartz n'ubwoko butandukanye bwa gems polishing.
Igishushanyo -Al2O3 gishobora gukoreshwa mu gusiga irangi ry'ibinyabutabire mu buryo bwa shimi
2.Kugira ngo habeho imashini zihindura imyuka ya hydrogenation
Kugira ngo huzuzwe ibisabwa mu ikoreshwa ry’umutungo wa peteroli n’amavuta meza, ikoranabuhanga rya hydrogenation ryakoreshejwe cyane, hydrogenation catalyst ni ingenzi mu ikoranabuhanga rya hydrogenation, rikoreshwa mu gukamura hydrogenation gamma alumina catalyst ubusanzwe igizwe na diaspore ntoya cyane binyuze mu gukaranga amazi, ifite ubuso bwihariye, aho yinjira n’aho ikwirakwira, ubuso bufite aside centre zitandukanye. Ingufu nziza za mekanike n’ubushyuhe buhamye, hamwe n’imiterere y’igiciro gito.
Katalogeri z'amashusho ni ingenzi mu gukora ibikomoka kuri peteroli
Mu nganda zigezweho zo gutunganya peteroli n’ibinyabutabire, ibirenga 90% by’imikorere y’ibinyabutabire bikorwa binyuze mu nzira ya catalytic, bityo catalytic yabaye urufunguzo rwo gukora uburyo bushya bwo gutunganya no gutunganya ibinyabutabire, iterambere ry’ibicuruzwa bishya. Mu nganda zitunganya peteroli, hakunze gukoreshwa catalytics zikomeye, zigizwe n’ibinyabutabire n’ibinyabutabire bikora. Catalytic ni igice cyihariye cya catalytics ikomeye, gishobora kongera ubuso bwihariye, kongera ubushobozi bwo kurwanya ubushyuhe n’imbaraga za mekanike. Catalytic IKORESHA ubwoko bwinshi bw’ibinyabutabire, nka: alumina, sieve ya molecular, silica gel, silica gel, activated carbon na diatomaceous earth. Ariko, ingano ya alumina itwara ibirenga kimwe cya kabiri cy’ingano yose ya catalytic. Catalytic cracking (FCC) catalytic ni ingenzi mu nzira ya catalytic cracking. Kubera ko peteroli isanzwe ku isi iremereye kandi iri hasi, mu kuvanga amavuta aremereye, amavuta asigaye yabaye uburyo bukoreshwa cyane mu gutunganya, bityo bisaba catalytic cracking (FCC) catalytic igomba kuba ikwirakwizwa rya molekile y’amavuta menshi mu mwobo munini, kandi umwobo munini uri hagati ugomba kugira aside ikwiye, muri kugira ngo hongerwe ubushobozi bwo gucika kw'ibinyabutabire bya macromolecular mu bikoresho fatizo. Alumina ikora ikunze gukoreshwa mu kunoza matrix ya catalyst. Ubwinshi bw'imyenge butuma ibinyabutabire bya macromolecular bikwirakwira mu duce twa catalyst, mu gihe ubuso bunini bwihariye butuma icyuma gikwirakwira, kugira ngo hongerwe imikorere ya catalyst.
3. Ikoreshwa nk'ubudodo
Imashini itwara diaspore ntoya ikoreshwa nk'umuhuza ntabwo ari ingirakamaro gusa mu gushushanya, izagira ingaruka no ku mikorere ya catalyst, abashakashatsi mu mushinga wa flue gas denitration selective catalytic reduction Ce – Mn/TiO2 catalyst mu gihe cyo guhuza diaspore ntoya nk'umuhuza, basanze ko idatuma ingufu za catalyst ziyongera cyane, ahubwo inanoza denitration surfactant selective catalyst.
4. Sana irangi rya -Al2O3
Igikorwa cyo gusiga urwego ku gikoresho gitwara ibintu gikoreshwa ni ukongera ubuso bwihariye bw'uburyo bukoreshwa cyane, gamma alumina ni kimwe mu bikoresho bikoreshwa cyane mu gusiga ibintu, gifite ubuso bwihariye, gifasha mu gukwirakwiza neza mu nzira yo gutera, gutegura irangi rya gamma alumina rikoreshwa cyane mu gusiga ibintu bikoreshwa mbere ya AlOOH, alumina sol ikaba yoroshye kuba diaspore nk'ibikoresho fatizo, gutegura, hakoreshejwe uburyo bwo koroshya uburyo bwo gushyira aside mu kirere, bishobora gukoreshwa mu nganda.
