Njengamanje, ukusetshenziswa okuyinhloko kwe-pseudo-boehmite kuyindlela eluhlaza yokulungisa i-alumina kanye ne-glue ye-catalyst noma i-catalyst carrier enzima. I-alumina elungiselelwe ngokuyosa i-pseudo-boehmite inendawo ephezulu ethile futhi isetshenziswa kabanzi njenge-catalyst kanye ne-catalyst carrier embonini ye-petrochemical.
1. esetshenziselwa izinto zokusetshenziswa ze-alumina ze-nanometer
Enye yezinto ezibalulekile ezisetshenziswa yi-pseudo-boehmite yizinto zokusetshenziswa ze-aluminium oxide. Ngokusekelwe ezicini zendawo enkulu ethile, umsebenzi ophezulu kanye nokunamathela okunamandla kwezinto zokusetshenziswa, isetshenziswe ukuhlanganisa izinto zokwakheka ezisezingeni lokushisa eliphezulu njengezinto zokwakheka ze-aluminium nitride. Ngaphezu kwalokho, i-nano-Al2O3 ifaneleka kakhulu ekupholiseni ngomshini wamakhemikhali (i-CMP), yi-nano-Al2O3 njengoba izinhlayiya zokugaya ezikhiqizwa yi-CMP slurry zingasetshenziswa engxenyeni ephakathi yenqubo yokukhiqiza ye-IC njengezinto zokuxhuma ze-semiconductor nezinto zefilimu ezifana ne-tungsten, i-aluminium, i-copper flattening, kanye ne-optical glass ethuthukisiwe, i-quartz crystal kanye nokupholisha okuhlukahlukene kwamagugu.
Isibalo -Al2O3 singasetshenziselwa izinhlayiya ezirhabaxa zokupholisha ngomshini zamakhemikhali
2.Ukuze uthole i-hydrogenation catalyst
Ukuze kuhlangatshezwane nezidingo zokusetshenziswa kwemithombo kaphethiloli kanye namafutha ahlanzekile, ubuchwepheshe obufakwe i-hydrogenation busetshenziswe kabanzi, i-hydrogenation catalyst iyisisekelo sobuchwepheshe be-hydrogenation, esetshenziselwa i-hydrogenation catalyst, i-gamma alumina carrier ivame ukwakhiwa yi-diaspore encane ngokosa amanzi emzimbeni, inobuso obuthile, indawo yokungena kanye nokusatshalaliswa kwe-pore okulungisekayo, kukhona isikhungo esihlukile se-acidic. Amandla angcono okusebenza kanye nokuzinza kokushisa, kanye nezici eziphansi.
Ama-catalyst ezithombe abalulekile ekukhiqizweni kwemikhiqizo kaphethiloli
Embonini yanamuhla yokuhlanzwa kwamafutha namakhemikhali, inqubo yokusabela kwamakhemikhali engaphezu kuka-90% itholakala ngenqubo yokulungisa, ngakho-ke i-catalyst isibe yisihluthulelo sokufeza inqubo entsha yokulungisa kanye namakhemikhali, ukuthuthukiswa komkhiqizo omusha. Embonini yokuhlanzwa kwamafutha, ama-catalyst aqinile avame ukusetshenziswa, akhiwa yi-carrier kanye nengxenye esebenzayo. I-catalyst iyingxenye ekhethekile ye-catalyst eqinile, engandisa indawo ethile ebusweni, ithuthukise ukumelana nokushisa kanye namandla omshini. I-catalyst IFISA izinhlobo eziningi ze-catalyst, njenge: i-alumina, isihlungo sama-molecule, i-silica gel, i-silica gel, i-activated carbon kanye ne-diatomaceous earth. Kodwa-ke, inani le-alumina catalyst libalelwa ngaphezu kwengxenye yenani eliphelele le-catalyst catalyst. I-catalyst ye-Catalytic cracking (FCC) iyisisekelo senqubo yokulungisa i-catalytic cracking. Njengoba uwoyela ongahluziwe emhlabeni unzima futhi uphansi, ekuhlanganiseni i-catalytic cracking impahla eluhlaza ehlanganisa uwoyela osindayo, uwoyela osele usuyindlela esetshenziswa kabanzi yokucubungula, ngakho-ke kudinga i-catalyst ye-catalytic cracking (FCC) kufanele ibe ukusabalala kwama-molecule kawoyela osindayo emgodini omkhulu, futhi umgodi omkhulu ophakathi kufanele ube nobuningi be-asidi obufanele, ukuze kuthuthukiswe ikhono lokuqhekeka kwe-catalyst lama-macromolecule compounds ezintweni zokusetshenziswa. I-alumina esebenzayo ivame ukusetshenziswa ukuthuthukisa i-catalyst matrix. Umthamo omkhulu we-pore uvumela ukusabalala kwama-macromolecule compounds ezinhlayiyeni ze-catalyst, kuyilapho indawo ephezulu ethile ivumela ukusabalala kwensimbi esebenzayo, ukuze kuthuthukiswe ukusebenza kokusabela kwe-catalyst.
3. Isetshenziswa njenge-glue
Isithwali se-diaspore esincane kakhulu esisetshenziswa njenge-ejenti yokubopha asigcini nje ngokuzuzisa ekubumbeni, sizophinde sithinte ukusebenza kwe-catalyst, abacwaningi ku-catalyst ye-flue gas denitration selective catalytic reduction Ce – Mn/TiO2 enqubweni yokujoyina i-diaspore encane njenge-ejenti yokubopha, bathole ukuthi akugcini nje ngokuthuthukisa kakhulu amandla omshini we-catalysts, kodwa futhi kuthuthukise i-catalyst ekhethiwe ye-denitration surfactant.
4.lungisa isembozo se--Al2O3
Umsebenzi wokumboza ungqimba esithwalweni somthwali womphezulu ukwandisa indawo ethile yobuso bendlela evame ukusetshenziswa, i-gamma alumina ingenye yezinto ezivame ukusetshenziswa kakhulu zokubopha, enendawo ephezulu yobuso ethize, isiza ekusabalaliseni okusebenzayo enkambisweni yokufakwa, ukulungiswa kokugqoka kwe-gamma alumina evame ukusetshenziswa ye-AlOOH precursor sol, i-alumina sol ibe yi-diaspore encane njengezinto zokusetshenziswa, ukulungiselela, ngokusebenzisa indlela yenqubo ye-acid peptization elula ukuyilawula, ingasetshenziswa ekukhiqizweni kwezimboni.
