The Structural Properties OfI-Alumina evuliwe
I-alumina ecushiwe inezici zomthamo omkhulu we-adsorption, indawo enkulu ethile engaphezulu, amandla aphezulu, nokuzinza okuhle kokushisa. into. Inobudlelwane obuqinile, i-desiccant engenabuthi, engagqwali, futhi umthamo wayo omile uphezulu. Isetshenziswa njenge-adsorbent, i-desiccant, i-catalyst kanye nomthwali ezinkambisweni eziningi zokusabela ezifana ne-petroleum, umanyolo wamakhemikhali kanye nomkhakha wamakhemikhali.
I-Alumina ecushiwe ingenye yemikhiqizo yamakhemikhali angaphili esetshenziswa kakhulu emhlabeni. Izakhiwo ze-alumina ecushiwe zichazwe ngezansi: I-alumina ecushiwe inokuzinza okuhle futhi ifaneleka njenge-desiccant, i-catalyst carrier, i-agent yokususa i-fluorine, i-adsorbent yokucindezela ukucindezela, i-agent ekhethekile yokuvuselela i-hydrogen peroxide, njll. I-alumina esebenzayo isetshenziswa kabanzi njenge-catalyst kanye ne-catalyst carrier.
I-alumina ecushiwe isetshenziswa njenge-desiccant, ikakhulukazi esetshenziswa emishinini yokomisa umfutho womoya ezimbonini, imishini yokomisa ingcindezi yomoya inengcindezi yokusebenza, ngokuvamile engaphansi kwe-0.8Mpa, edinga isilinganiso esicushiwe se-alumina ukuze sibe namandla amahle emishini, uma amandla emishini eningi kakhulu. okuphansi, kulula ukwenza i-powder, i-powder kanye nenhlanganisela yamanzi izovimbela ngokuqondile ipayipi lemishini, ngakho-ke, Inkomba ebalulekile ye-alumina ecushiwe esetshenziswa njenge-desiccant ingamandla, imishini yokomisa umfutho womoya, ngokuvamile amathangi amabili, amathangi amabili asebenza ngokushintshana, empeleni. i-adsorption saturation → inqubo yomjikelezo wokuhlaziya, i-desiccant ngokuyinhloko ingamanzi e-adsorption, kodwa ngaphansi kwezimo ezingokoqobo zokusebenza, umthombo womshini wokomisa umfutho womoya uzoba namafutha, ukugqwala nokunye ukungcola, Lezi zici zizothinta ngokuqondile impilo yesevisi ye-alumina adsorbent ecushiwe, ngoba icushiwe. I-alumina iyimpahla ye-adsorption ene-porous, i-polarity yemvelo ye-adsorption yamanzi, i-oyela adsorption nayo inhle kakhulu, kodwa uwoyela uzoxhuma ngokuqondile i-alumina adsorption pore ecushiwe, ukuze ukulahlekelwa izici ze-adsorption, kube nokugqwala, ukugqwala emanzini, okunamathiselwe ebusweni be-alumina. I-alumina ecushiwe, Izokwenza i-alumina ecushiwe ilahlekelwe umsebenzi ngokuqondile, ngakho-ke ku-alumina ecushiwe njengokusetshenziswa kwe-desiccant, zama ukugwema ukuthintana namafutha, ukugqwala, i-alumina ecushiwe i-adsorbent njenge-desiccant ejwayelekile yokuphila kweminyaka engu-1 ~ 3, ukusetshenziswa kwangempela kuyoba ukomisa igesi. iphuzu lamazolo lokunquma ukuthi uzoyishintsha yini i-alumina ecushiwe. Izinga lokushisa lokuvuselelwa kwe-alumina ecushiwe liphakathi kuka-180 ~ 350 ℃. Ngokuvamile, izinga lokushisa lombhoshongo we-alumina ocushiwe likhuphukela ku-280 ℃ amahora angu-4. I-alumina ecushiwe isetshenziswa njenge-ejenti yokwelapha amanzi, futhi isisombululo se-aluminium sulfate sisetshenziswa njenge-regenerator. Isixazululo se-aluminium sulfate regenerator singu-2 ~ 3%, i-alumina evuliwe ngemva kokugcwaliswa kwe-adsorption ifakwa ekufakweni kwesisombululo se-aluminium sulfate, lahla isisombululo, geza ngamanzi ahlanzekile izikhathi ezingu-3 ~ 5. Ngemuva kokusetshenziswa isikhathi eside, indawo ye-alumina ecushiwe inombala ophuzi futhi umphumela we-defluorination uyancipha, okubangelwa ukukhanyiswa kokungcola. Ingelashwa nge-3% hydrochloric acid isikhathi esingu-1 bese ivuselelwa ngale ndlela engenhla.
