Izicelo ze-Alumina ezisebenza

Njengekhabhoni evuselelwe, indawo ephezulu kanye nobukhulu obubonakalayo yi-alumina evuselelwe kuvumela ukuthi ibambe futhi ibambe izinhlobo ezahlukene zezinto zokwakha, okwenza ukuthi isetshenziswe njenge-adsorbent, i-desiccant, nokuningi. Izindlela eziyinhloko zokusetshenziswa kwemikhiqizo ye-alumina evuselelwe zifaka:

IZINTO EZINOKUDLA

I-alumina esebenzayo iyi-adsorbent ephumelela kakhulu kokubili ekusetshenzisweni kwegesi kanye noketshezi, futhi ngenxa yalokho, isetshenziswa yizimboni eziningana ukususa izingxenye eziqondiwe kwezinye izinto.

Njenge-adsorbent, i-alumina esebenzayo yaziwa kakhulu nge-se yayo ekuhlungeni amanzi, lapho isebenza khona njenge-adsorbent engabizi kakhulu yokususa i-fluoride emanzini. Iyakwazi futhi ukususa ezinye izinto ezingcolisayo, okuhlanganisa i-arsenic, i-lead, ne-sulfur.

I-DESICCANT

Njengendima yayo njenge-adsorbent, i-alumina esebenzayo ingamunca amanzi emoyeni, okuvumela ukuthi isetshenziswe njenge-desiccant; i-alumina esebenzayo ingabamba futhi ibambe amanzi ukuze igcine izinto zomile, njengejeli le-silica. Njenge-desiccant, i-alumina esebenzayo ingamunca kufika ku-20% wesisindo sayo emanzini kumswakama olinganiselwe ongu-50%.

I-alumina esebenzayo isetshenziswa njenge-desiccant ezinhlotsheni eziningi zokusebenza, okuhlanganisa nokususwa komhwamuko wamanzi emagesi ezindaweni zezimboni. Amanzi afakwe kwi-alumina esebenzayo angasuswa ngokwelashwa ngokushisa bese i-alumina isetshenziswa futhi.

IZIKHALISTHI

I-alumina esebenzayo isetshenziswa kabanzi njenge-catalyst, enezindima njenge-catalyst uqobo lwayo, kanye nesithwali esingasebenzisi i-inert, noma i-substrate yezinye izinto ezibangela i-catalyst.

Njenge-catalyst, i-alumina esebenzayo yaziwa kakhulu ngendima yayo njenge-catalyst ye-Claus; i-alumina esebenzayo iyi-catalyst ye-Claus esetshenziswa kakhulu emizamweni yokubuyisa isibabule ezindaweni zokuhlanza uwoyela negesi.

ISIPHETHO

Ngenxa yamakhono ayo njenge-adsorbent, i-desiccant, kanye ne-catalyst, i-alumina esebenzayo iyithuluzi eliwusizo ezindaweni eziningi zenqubo yezimboni. Ikhiqizwa ngokusebenzisa i-aluminium oxide ephuma enkambisweni ye-Bayer nge-calcination, i-alumina esebenzayo ingenziwa ngokwezifiso kakhulu futhi ivame ukuhlanganiswa ukuze kuthuthukiswe ukusebenza kanye nezici zokuphatha. Ukuhlolwa kokungenzeka kuvame ukuba yinto ewusizo lapho usebenza nemikhiqizo ye-alumina esebenzayo.
