Ukubuka konke kwe-alumina esebenzayo
I-alumina esebenzayo, eyaziwa nangokuthi i-bauxite esebenzayo, ibizwa ngokuthi i-alumina esebenzayo ngesiNgisi. I-alumina esetshenziswa kuma-catalyst ivame ukubizwa ngokuthi “i-alumina esebenzayo”. Iyinto eqinile enezimbobo, ehlakazeke kakhulu enendawo enkulu ebusweni. Ubuso bayo obunezimbobo ezincane bunezici ezidingekayo ukuze kulungiswe i-catalysis, njengokusebenza kokumuncwa, umsebenzi wobuso, ukuzinza okuhle kakhulu kokushisa, njll., ngakho-ke isetshenziswa kabanzi njengesikhuthazi kanye nesithwali se-catalyst se-reaction yamakhemikhali.
I-spherical activated alumina pressure swing oil adsorbent iyizinhlayiya ezimhlophe eziyizimbobo eziyindilinga. I-activated alumina inosayizi wezinhlayiya ofanayo, indawo ebushelelezi, amandla aphezulu omshini, i-hygroscopicity enamandla, ayivuvuki futhi ayiqhekeki ngemva kokumuncwa kwamanzi, futhi ihlala ingashintshi. Ayinabo ubuthi, ayinaphunga, futhi ayincibiliki emanzini nase-ethanol.
I-Alumina
Ayincibiliki emanzini futhi ingancibilika kancane kancane ku-sulfuric acid egxilile. Ingasetshenziswa ukucwenga i-aluminium yensimbi futhi iyinto eluhlaza yokwenza izinto ezivuthayo, i-porcelain, izinto eziphikisayo kanye namatshe ayigugu okwenziwa.
I-Alumina esetshenziswa njenge-adsorbent, i-catalyst kanye ne-catalyst carrier ibizwa ngokuthi “i-activated alumina”. Inezici ze-porosity, ukusabalala okuphezulu kanye nendawo enkulu ethile. Isetshenziswa kabanzi ekwelapheni amanzi, e-petrochemical, emakhemikhali amancane, e-biological kanye nasemkhakheni wezokwelapha.
Izici ze-alumina
1. Indawo enkulu ethile: i-alumina esebenzayo inendawo ephezulu ethile. Ngokulawula ngokufanele uhlelo lokusila lwe-alumina, i-alumina esebenzayo enendawo ethile ephakeme njengo-360m2 / G ingalungiswa. I-alumina esebenzayo elungiselelwe ngokusebenzisa i-colloidal aluminium hydroxide ebolile yi-NaAlO2 njengezinto zokusetshenziswa inosayizi omncane kakhulu wembobo kanye nendawo ethile ephezulu njengo-600m2 / g.
2. Isakhiwo sosayizi wembobo elungisekayo: Ngokuvamile, imikhiqizo enosayizi wembobo ephakathi ingalungiswa ngokubhaka nge-aluminium hydroxide emsulwa. Imikhiqizo enosayizi wembobo emincane ingalungiswa ngokulungiselela i-alumina esebenzayo nge-aluminium glue, njll. kuyilapho i-alumina esebenza ngosayizi wembobo enkulu ingalungiswa ngokungeza ezinye izinto eziphilayo, njenge-ethylene glycol kanye ne-fiber, ngemva kokusha.
3. Ubuso bune-asidi futhi bunokuqina okuhle kokushisa.
Umsebenzi we-alumina esebenzayo
I-alumina esebenzayo ingeyesigaba se-alumina yamakhemikhali, esetshenziswa kakhulu njenge-adsorbent, i-water purifier, i-catalyst kanye ne-catalyst carrier. I-alumina esebenzayo inekhono lokumunca amanzi ngokukhetha kugesi, umhwamuko wamanzi kanye noketshezi oluthile. Ngemva kokuba i-adsorption isigcwele, ingashiswa cishe ku-175-315. D egree. I-adsorption kanye ne-reactivation kungenziwa izikhathi eziningi.
Ngaphezu kokusetshenziswa njenge-desiccant, ingamunca futhi umusi wamafutha okugcoba ovela emoyeni ongcolile, i-hydrogen, i-carbon dioxide, igesi yemvelo, njll. Futhi ingasetshenziswa njenge-catalyst kanye ne-catalyst support kanye nokusekela ukuhlaziywa kwe-chromatographic.
Ingasetshenziswa njenge-ejenti yokususa uketshezi emanzini okuphuza ane-fluorine ephezulu (ene-defluorinating potential enkulu), i-ejenti yokususa uketshezi oluketshezi olujikeleza ama-alkanes ekukhiqizweni kwe-alkylbenzene, i-ejenti yokususa i-acid nokuvuselela uwoyela we-transformer, i-ejenti yokomisa igesi embonini yokwenza i-oxygen, imboni yezindwangu kanye nemboni ye-elekthronikhi, i-ejenti yokomisa yomoya wezinsimbi ozenzakalelayo, kanye ne-ejenti yokomisa kanye ne-ejenti yokuhlanza kumanyolo wamakhemikhali, ukomisa nge-petrochemical kanye neminye imboni.
