Izicelo ze-alumina ezivuselelweyo

Njengekhabhoni esebenzayo, indawo ephezulu kunye nobukhulu obubonakalayo yi-alumina esebenzayo ivumela ukuba ibambe kwaye ibambe iintlobo ngeentlobo zezinto, nto leyo eyenza ukuba isetyenziswe njenge-adsorbent, desiccant, nokunye. Iindlela eziphambili zokusetyenziswa kweemveliso ze-alumina ezisebenzayo ziquka:

IINKCUKACHA

I-alumina esebenzayo iyasebenza kakhulu ekunyuseni igesi kunye nokusetyenziswa kolwelo, kwaye ngenxa yoko, isetyenziswa ngamashishini amaninzi ukususa izinto ezithile kwezinye izinto.

Njenge-adsorbent, i-alumina esebenzayo yaziwa kakhulu nge-se yayo ekuhluzeni amanzi, apho isebenza njenge-adsorbent engabizi kakhulu yokususa i-fluoride emanzini. Ikwakwazi ukususa ezinye izinto ezingcolisayo, kuquka i-arsenic, i-lead, kunye ne-sulfur.

I-DESICCANT

Njengendima yayo njenge-adsorbent, i-alumina esebenzayo ingakwazi ukufunxa amanzi emoyeni, nto leyo evumela ukuba isetyenziswe njenge-desiccant; i-alumina esebenzayo inokubamba kwaye ibambe amanzi ukuze izinto zihlale zomile, njenge-silica gel. Njenge-desiccant, i-alumina esebenzayo inokufunxa ukuya kuthi ga kwi-20% yobunzima bayo emanzini kumswakama we-50%.

I-alumina esebenzayo isetyenziswa njenge-desiccant kwiindlela ezahlukeneyo zokusebenza, kuquka nokususwa komphunga wamanzi kwiigesi kwiindawo zoshishino. Amanzi afakwe kwi-alumina esebenzayo anokususwa ngonyango lobushushu kwaye i-alumina isetyenziswe kwakhona.

IZIKHATHALISHI

I-alumina esebenzayo ikwasetyenziswa kakhulu njenge-catalyst, ineendima njenge-catalyst ngokwayo, kunye ne-inert carrier, okanye i-substrate yezinye ii-catalysts.

Njenge-catalyst, i-alumina esebenzayo yaziwa kakhulu ngendima yayo njenge-Claus catalyst; i-alumina esebenzayo yeyona i-Claus catalyst esetyenziswa kakhulu kwimisebenzi yokubuyisa isalfure kwiindawo zokucoca ioyile negesi.

ISIPHELO

Ngenxa yezakhono zayo njenge-adsorbent, i-desiccant, kunye ne-catalyst, i-alumina esebenzayo sisixhobo esibalulekileyo kwiimeko ezininzi zenkqubo yemizi-mveliso. Yenziwe ngokusebenza kwe-aluminium oxide ephuma kwinkqubo yeBayer nge-calcination, i-alumina esebenzayo iyakwazi ukwenziwa ngokwezifiso kakhulu kwaye idla ngokuhlanganiswa ukuze kuphuculwe ukusebenza kunye neempawu zokuphatha. Uvavanyo lokwenzeka ludla ngokuba ngumsebenzi oluncedo xa usebenza ngeemveliso ze-alumina ezisebenzayo.
