Isishwankathelo se-alumina esebenzayo
I-alumina esebenzayo, eyaziwa ngokuba yi-activated bauxite, ibizwa ngokuba yi-activated alumina ngesiNgesi. I-alumina esetyenziswa kwi-catalysts idla ngokubizwa ngokuba yi-"activated alumina". Yinto eqinileyo enemingxuma, esasazeke kakhulu enendawo enkulu yomphezulu. Umphezulu wayo onemingxuma emincinci uneempawu ezifunekayo kwi-catalysis, ezinje ngokusebenza kwe-adsorption, umsebenzi womphezulu, uzinzo oluhle kakhulu lobushushu, njl.njl., ngoko ke isetyenziswa kakhulu njenge-catalyst kunye ne-catalyst carrier kwiimpendulo zeekhemikhali.
I-spherical activated alumina pressure swing oil adsorbent yi-white spherical porous particles. I-activated alumina inobukhulu obufanayo be-particles, umphezulu ogudileyo, amandla aphezulu oomatshini, i-hygroscopicity enamandla, ayidumbi kwaye ayiqhekeki emva kokufunxwa kwamanzi, kwaye ayitshintshi. Ayinatyhefu, ayinavumba, kwaye ayinyibiliki emanzini nakwi-ethanol.
I-Alumina
Ayinyibiliki emanzini kwaye inokunyibilika kancinci kwi-asidi ye-sulfuric exineneyo. Ingasetyenziselwa ukucokisa i-aluminium yesinyithi kwaye ikwayinto eluhlaza yokwenza izinto eziqhotsiweyo, i-porcelain, izinto ezirhabaxa kunye namatye anqabileyo okwenziwa.
I-Alumina esetyenziswa njenge-adsorbent, i-catalyst kunye ne-catalyst carrier ibizwa ngokuba yi-"activated alumina". Ineempawu ze-porosity, i-dispersion ephezulu kunye nommandla omkhulu womphezulu. Isetyenziswa kakhulu kunyango lwamanzi, i-petrochemical, iikhemikhali ezincinci, iibhayoloji kunye namayeza.
Iimpawu ze-alumina
1. Indawo enkulu ethile: i-alumina esebenzayo inomphezulu othile ophezulu. Ngokulawula ngokufanelekileyo inkqubo yokusila ye-alumina, i-alumina esebenzayo enomphezulu othile ofikelela kwi-360m2 / G ingalungiswa. I-alumina esebenzayo elungiselelwe ngokusebenzisa i-colloidal aluminum hydroxide eboliswe yi-NaAlO2 njengezinto eziluhlaza inobukhulu obuncinci kakhulu be-pore kunye nomphezulu othile ofikelela kwi-600m2 / g.
2. Ulwakhiwo lobungakanani bembobo ehlengahlengiswayo: Ngokubanzi, iimveliso ezinobukhulu bembobo ephakathi zinokulungiswa ngokubhaka nge-aluminium hydroxide ecocekileyo. Iimveliso ezinobukhulu bembobo ezincinci zinokulungiswa ngokulungiselela i-alumina esebenzayo ngeglu ye-aluminium, njl.njl. ngelixa i-alumina esebenzayo enobukhulu bembobo enkulu inokulungiselelwa ngokongeza ezinye izinto eziphilayo, ezifana ne-ethylene glycol kunye nefayibha, emva kokutsha.
3. Umphezulu uneasidi kwaye unozinzo oluhle lobushushu.
Umsebenzi we-alumina esebenzayo
I-alumina esebenzayo ikwiqela le-alumina yeekhemikhali, esetyenziswa kakhulu njenge-adsorbent, i-water purifier, i-catalyst kunye ne-catalyst carrier. I-alumina esebenzayo inamandla okufunxa amanzi ngokukhetha kwigesi, umphunga wamanzi kunye nolwelo oluthile. Emva kokuba i-adsorption igcwele, inokufudunyezwa malunga ne-175-315. D egree. I-adsorption kunye ne-reactivation zingenziwa amaxesha amaninzi.
Ukongeza ekusetyenzisweni njenge-desiccant, inokufunxa umphunga weoyile othambisayo kwi-oksijini engcolisiweyo, i-hydrogen, i-carbon dioxide, igesi yendalo, njl. Kwaye ingasetyenziselwa njenge-catalyst kunye ne-catalyst inkxaso kunye nenkxaso yohlalutyo lwe-chromatographic.
Ingasetyenziswa njengesixhobo sokususa ulwelo emanzini okusela ane-fluorine eninzi (enomthamo omkhulu wokususa ulwelo), isixhobo sokususa ulwelo kwi-alkanes ezijikeleza imveliso ye-alkylbenzene, i-arhente yokususa i-asidi nevuselelayo yeoyile ye-transformer, i-arhente yokomisa igesi kwishishini lokwenza ioksijini, ishishini lelaphu kunye neshishini le-elektroniki, i-arhente yokomisa yomoya wezixhobo ngokuzenzekelayo, kunye ne-arhente yokomisa kunye ne-arhente yokucoca kwi-chemical fertilizer, i-petrochemical drying kunye neminye imboni.
