I-alumina esebenzayo

I-alumina esebenzayo (ifomula yama-molecule i-Al2O(3-x)(OH)2x,0 < x < 0.8) ingenye yemikhiqizo yamakhemikhali angaphili esetshenziswa kakhulu emhlabeni. Ngenxa yesakhiwo sayo esinezimbobo, indawo ephezulu yobuso kanye nesimo sokuguquka esingazinzile, i-alumina esebenzayo inomsebenzi omkhulu. Isetshenziswa kabanzi njenge-catalyst kanye ne-catalyst carrier embonini ye-petrochemical kanye nemboni yomanyolo. I-alumina esebenzayo inezici zokungenisa, ngakho-ke isetshenziswa njenge-desiccant yegesi noketshezi, i-adsorbent yokuhlanza igesi, i-ejenti yokususa uketshezi emanzini okuphuza, i-ejenti yokususa umbala kanye nephunga lendle yezimboni, njll. Njengamanje, imikhiqizo eyinhloko ye-alumina esebenzayo yezimboni ikhiqizwa ngokuphuma kwamanzi ngokushesha. I-alumina esebenzayo ibhekisela ku-alumina ene-calcined egayiwe kahle ngokuphelele futhi ngokuyinhloko yakhiwe yi-(20%-90%) i-alpha-al2o3 enobukhulu bekristalu bokuqala obuyi-1 micron. Ifomula: Al2O3, Isisindo sama-Molecular: 101.96.

I-alumina esebenzayo isetshenziswa kabanzi ku-petrochemical, ukuhlanzwa kwamafutha, i-elekthronikhi, i-ethylene, i-propylene, umoya kanye nezinye izinto zokomisa, isetshenziswe ezitshalweni eziningi ze-hydrogen peroxide, izitshalo zomanyolo, izitshalo ze-oxygen kanye namayunithi okuhlanza i-petrochemical, futhi ithole imiphumela emihle. Ibhola le-alumina elisebenzayo liphinde libe ne-polarity ye-adsorbent ukunquma amandla amanzi, i-oxide, i-acetic acid, i-alkali kanye nokunye ukusondelana okuqinile, liyi-desiccant yokujula komswakama, i-adsorption yama-molecule e-polar. Ingasetshenziswa kabanzi ekomiseni okujulile kwegesi yokuqhekeka kwephethiloli, igesi ye-ethylene propylene, ukukhiqizwa kwe-hydrogen, idivayisi yokuhlukanisa umoya, umshini wokomisa umoya wensimbi, ukwelashwa kwe-fluoride ku-hydrogen peroxide, futhi ingasusa igesi yesulfure i-hydrogen, i-carbon dioxide, i-hydrogen fluoride, ama-hydrocarbon kanye nokunye ukungcola kugesi engcolile, ikakhulukazi efanelekile emanzini aqukethe i-fluorine.

I-alumina esebenzayo imhlophe noma incane, inombala obomvu omncane, inoboya obuningi kanye nomsebenzi omude, inamandla okuphatha kahle, ivuselela kalula, okuqukethwe kokuphazamiseka kuncane, ngaphandle kwalabo abasebenzisa amanzi okuphuza ngaphandle kwesenzo se-fluorine, ingasasetshenziswa njenge-adsorbent, desiccant kanye ne-catalyst carrier. Isetshenziswa kabanzi kubunjiniyela bamanzi ompompi, ubunjiniyela bokuhlanza amanzi, isitshalo se-hydrogen peroxide, isitshalo somanyolo, isitshalo se-oxygen kanye nemboni ye-petrochemical. I-alumina esebenzayo inezakhiwo zokufaka i-adsorption, umsebenzi we-catalytic we-porous, ukuhlakazeka okuphezulu, indawo enkulu ethile ye-alumina, efanelekile ezinhlobonhlobo zegesi kanye nokomiswa koketshezi, ingasetshenziswa emanzini okuphuza kanye nemishini yezimboni i-deoxidization, i-dearsenization, i-dearsenization, i-sewage decolorization, i-deodoration njalo njalo. Lo mkhiqizo wenziwe nge-alumina ehlanzekile kakhulu ngokulungiselela kwesayensi kanye nokuqedwa kwe-catalytic. Isetshenziswa njenge-adsorbent, desiccant, catalyst kanye ne-catalyst ezinqubweni eziningi zokusabela njenge-petroleum, umanyolo wamakhemikhali kanye nemboni yamakhemikhali. Ngokusho kokusetshenziswa kwayo, ihlukaniswe phakathi: iyasebenza i-alumina adsorbent, i-desiccant kanye ne-catalyst carrier.

I-alumina esebenzayo yenziwe nge-alumina emsulwa kakhulu ngokulungiselela kwesayensi kanye nokuqedwa kwe-catalytic. Izinhlayiya ezimhlophe eziyindilinga ezinezimbobo, ubukhulu bezinhlayiya buyafana, ubuso obubushelelezi, amandla omshini, i-hygroscopicity eqinile, ngemva kokumuncwa kwamanzi akwandi futhi akwaphuki imikhiqizo yokuqala, engeyona enobuthi, ayinambitheki, ayinaphunga, ayincibiliki emanzini nasezinhlayiyeni eziphilayo. Iyi-molecule adsorbent enendawo enkulu ethile. Lapho inani le-PH kanye ne-alkalinity yamanzi aluhlaza kuphansi, amandla okususa i-fluorine aphakeme kuno-3.0mg/g. Ingasetshenziswa emanzini okuphuza kanye nemishini yezimboni yokususa i-fluorination, i-dearsenic, ukususwa kombala wendle, ukususwa kwephunga, njll. Imikhiqizo eyinhloko yile: i-alumina fluoride remover esebenzayo, i-alumina desiccant esebenzayo, i-alumina catalyst esebenzayo, i-hydrogen peroxide ekhethekile esebenzayo.

I-desiccant ye-alumina esebenzayo: lo mkhiqizo uhlobo lwezinto ezincane nezinezimbobo ezincane neziyindilinga, ezinomsebenzi oqinile wokumunca, indawo enkulu ethile, ubulukhuni obuphezulu bokucindezela, impilo yenkonzo ende, futhi zingasetshenziswa ngokuphindaphindiwe ngendlela yokuvuselela. Lo mkhiqizo umhlophe, uyisiyingi sezinto ezinezimbobo ezingenabo ubuthi, awunaphunga, awuphuphu, awuncibiliki emanzini. Usetshenziswa kabanzi embonini ye-petrochemical, embonini yamakhemikhali, embonini yezindwangu, embonini yegolide nakwezinye izimboni, njengokomisa umoya wezinsimbi, idivayisi yokuhlukanisa umoya we-adsorption swing, iphuzu lamazolo lomunca lingafinyelela ngaphezu kwama-degrees angu-41, futhi lingasetshenziswa ensimbi, igesi yokuqhekeka kwephethiloli, i-ethylene, i-propylene esigabeni soketshezi kanye nesigaba segesi.
