ZOFUNIKA ZOTHANDIZA ZOKHUDZA ALUMINA

Mofanana ndi mpweya wopangidwa ndi activated carbon, malo okwera komanso porosity yomwe imawonekera ndi alumina yopangidwa ndi activated imalola kuti igwire ndikusunga mitundu yosiyanasiyana ya zinthu, zomwe zimapangitsa kuti igwiritsidwe ntchito ngati adsorbent, desiccant, ndi zina zotero. Njira zazikulu zomwe zinthu za alumina zogwiritsidwa ntchito zimagwiritsidwa ntchito ndi izi:

ZOKHUDZA

Alumina yogwira ntchito ndi yothandiza kwambiri pochotsa zinthu zina kuchokera ku zinthu zina monga mpweya ndi madzi, ndipo motero, imagwiritsidwa ntchito ndi mafakitale ambiri pochotsa zinthu zina kuchokera ku zinthu zina.

Monga adsorbent, alumina yogwira ntchito imadziwika kwambiri chifukwa cha sefa yake m'madzi, komwe imagwira ntchito ngati adsorbent yotsika mtengo yochotsera fluoride m'madzi. Imathanso kuchotsa zinthu zina zodetsa, kuphatikizapo arsenic, lead, ndi sulfure.

CHITSULO CHA DESICCANT

Mofanana ndi ntchito yake ngati adsorbent, alumina yogwira ntchito imathanso kuyamwa madzi kuchokera mumlengalenga, zomwe zimapangitsa kuti agwiritsidwe ntchito ngati desiccant; alumina yogwira ntchito imatha kugwira ndi kusunga madzi kuti zinthu ziume, monga silika gel. Monga desiccant, alumina yogwira ntchito imatha kuyamwa mpaka 20% ya kulemera kwake m'madzi pa chinyezi cha 50%.

Alumina yogwiritsidwa ntchito imagwiritsidwa ntchito ngati desiccant m'njira zosiyanasiyana, kuphatikizapo kuchotsa nthunzi ya madzi kuchokera ku mpweya m'mafakitale. Madzi omwe amamatiridwa pa alumina yogwiritsidwa ntchito amatha kuchotsedwa pogwiritsa ntchito kutentha ndipo alumina imagwiritsidwanso ntchito.

ZOPANGIRA

Alumina yogwiritsidwa ntchito imagwiritsidwanso ntchito kwambiri ngati chothandizira, chokhala ndi ntchito ngati chothandizira chokha, komanso chonyamulira chosagwira ntchito, kapena gawo la zothandizila zina.

Monga chothandizira, alumina yogwira ntchito imadziwika bwino chifukwa cha ntchito yake ngati chothandizira cha Claus; alumina yogwira ntchito ndiyo chothandizira cha Claus chomwe chimagwiritsidwa ntchito kwambiri pantchito zobwezeretsa sulfure m'mafakitale opangira mafuta ndi gasi.

MAPETO

Chifukwa cha mphamvu zake monga adsorbent, desiccant, komanso catalyst, alumina yoyatsidwa ndi chida chofunikira kwambiri m'mafakitale ambiri. Yopangidwa kuchokera ku kuyatsa kwa aluminiyamu oxide yomwe imachokera ku njira ya Bayer kudzera mu calcination, alumina yoyatsidwa imatha kusinthidwa mosavuta ndipo nthawi zambiri imagwirizanitsidwa kuti ikonze magwiridwe antchito ndi magwiridwe antchito. Kuyesa kuthekera nthawi zambiri kumakhala kothandiza pogwira ntchito ndi zinthu za alumina zoyatsidwa.
