I-alumina esebenzayo

I-alumina esebenzayo (ifomula yemolekyuli i-Al2O(3-x)(OH)2x,0 < x < 0.8) yenye yeemveliso zeekhemikhali ezingasetyenziswanga ezisetyenziswa kakhulu kwihlabathi liphela. Ngenxa yesakhiwo sayo esineembobo, indawo ephezulu ethile kunye nemeko yokutshintsha engaguqukiyo, i-alumina esebenzayo inomsebenzi omkhulu. Isetyenziswa kakhulu njenge-catalyst kunye ne-catalyst carrier kwishishini le-petrochemical kunye neshishini lesichumisi. I-alumina esebenzayo ineempawu zokufunxa, ngoko ke isetyenziswa njenge-desiccant yegesi kunye nolwelo, i-adsorbent yokucoca igesi, i-agent yokususa ifluorination yamanzi okusela, i-agent yokususa umbala kunye nevumba kwi-indle yemizi-mveliso, njl. Okwangoku, iimveliso eziphambili ze-alumina ezisebenzayo ziveliswa kukuphelelwa ngamanzi ngokukhawuleza. I-alumina esebenzayo ibhekisa kwi-alumina ene-calcined ecoliweyo ngokupheleleyo kwaye yenziwe ngokusisiseko yi-alpha-al2o3 (20%-90%) enobukhulu bekristale yokuqala ye-1 micron. Ifomula: Al2O3, Ubunzima beMolekyuli: 101.96.

I-alumina esebenzayo isetyenziswa kakhulu kwi-petrochemical, i-oyile yokucocwa, izixhobo ze-elektroniki, i-ethylene, i-propylene, umoya kunye nezinye izixhobo zokomisa, isetyenzisiwe kwizityalo ezininzi ze-hydrogen peroxide, izityalo zezichumisi, izityalo ze-oksijini kunye neeyunithi zokucoca i-petrochemical, kwaye ifumene iziphumo ezilungileyo. Ibhola ye-alumina esebenzayo nayo ngokwe-polarity ye-adsorbent ukumisela amandla amanzi, i-oxide, i-acetic acid, i-alkali kunye nezinye izinto ezinamandla, yi-desiccant yobunzulu bomswakama, i-adsorption yeemolekyuli ze-polar. Ingasetyenziswa kakhulu ekomiseni okunzulu kwegesi yokuqhekeka kwepetroliyam, igesi ye-ethylene propylene, imveliso ye-hydrogen, isixhobo sokwahlulwa komoya, umatshini wokomisa umoya wesixhobo, unyango lwe-fluoride kwi-hydrogen peroxide, ikwanokususa igesi yesalfure i-hydrogen, i-carbon dioxide, i-hydrogen fluoride, ii-hydrocarbons kunye nezinye izinto ezingcolisayo kwigesi yenkunkuma, ngakumbi efanelekileyo emanzini aqulethe i-fluorine.

I-alumina esebenzayo imhlophe okanye incinci, ibomvu kancinci, inoboya obuninzi kwaye inomsebenzi omde, iyasebenza kakuhle, inamandla okulawula amanzi e-fluorine aphantsi, kulula ukuyivuselela, umxholo wokuphazamiseka awuncinci, ngaphandle kwabo basebenzisa amanzi okusela ngaphandle kwe-fluorine, basenokuyisebenzisa njenge-adsorbent, desiccant kunye ne-catalyst carrier. Isetyenziswa kakhulu kubunjineli bamanzi epompo, ubunjineli bokucoca amanzi, isityalo se-hydrogen peroxide, isityalo sesichumiso, isityalo seoksijini kunye neshishini le-petrochemical. I-alumina esebenzayo ineempawu ze-adsorption, umsebenzi we-catalytic we-porous, i-dispersion ephezulu, indawo enkulu ethile ye-alumina, ifanelekile kwiindidi ezahlukeneyo zegesi kunye nolwelo, ingasetyenziselwa amanzi okusela kunye nezixhobo zoshishino i-deoxidization, i-dearsenization, i-sewage decolorization, i-deodoration njl.njl. Le mveliso yenziwe nge-alumina ecocekileyo kakhulu ngokulungiselela ngokwesayensi kunye nokugqiba i-catalytic. Isetyenziswa njenge-adsorbent, desiccant, catalyst kunye ne-catalyst kwiinkqubo ezininzi zokuphendula ezifana nepetroleum, i-chemical fertilizer kunye neshishini leekhemikhali. Ngokwendlela esetyenziswa ngayo, zingahlulwa zibe: ziyasebenza i-alumina adsorbent, i-desiccant kunye ne-catalyst carrier.

I-alumina esebenzayo yenziwe nge-alumina ecocekileyo kakhulu ngokulungiselela ngokwesayensi kunye nokugqitywa kwe-catalytic. Iisuntswana ezimhlophe ezingqukuva, ubungakanani besuntswana buyafana, umphezulu ogudileyo, amandla oomatshini, i-hygroscopicity enamandla, emva kokufunxwa kwamanzi akwandi kwaye aziqhekeki iimveliso zokuqala, ezingezizo iityhefu, azinancasa, azinavumba, azinyibiliki emanzini nakwizinyibilikisi zendalo. Yi-molecule adsorbent enendawo enkulu yomphezulu. Xa ixabiso le-PH kunye ne-alkalinity yamanzi aluhlaza ziphantsi, amandla okususa i-fluorine aphezulu kune-3.0mg/g. Ingasetyenziswa emanzini okusela nakwizixhobo zoshishino ukususa i-fluorination, i-dearsenic, i-sewage decolorization, i-deodorization, njl. Iimveliso eziphambili zezi: i-alumina activated fluoride remover, i-activated alumina desiccant, i-activated alumina catalyst, i-hydrogen peroxide special activated alumina.

I-desiccant ye-alumina esebenzayo: le mveliso luhlobo lwezinto ezincinci nezingqukuva, ezinomsebenzi onamandla wokufunxa, indawo enkulu ethile, ubunzima obuphezulu bokucinezela, ubomi benkonzo ende, kwaye ingasetyenziswa ngokuphindaphindiweyo ngendlela yokuvuselela. Le mveliso imhlophe, ingqukuva yezinto ezingenazimbovane ayinatyhefu, ayinavumba, ayiguquki, ayinyibiliki emanzini. Isetyenziswa kakhulu kushishino lwe-petrochemical, kushishino lweekhemikhali, kushishino lwelaphu, kushishino lwegolide nakwamanye amashishini, anjengokomisa umoya kwizixhobo, isixhobo sokwahlula umoya ngokucinezela, indawo yokufunxa inokufikelela kwiidigri ezingama--41, ikwasetyenziselwa intsimbi, igesi yokuqhekeka kwepetroli, i-ethylene, i-propylene kwisigaba solwelo kunye nesigaba segesi.
