Pfupiso yealumina yakabatidzwa
Alumina yakabatidzwa, inozivikanwawo se activated bauxite, inonzi activated alumina muchirungu. Alumina inoshandiswa muma catalysts inowanzonzi "activated alumina". Ichinhu chakasimba chine maburi, chakapararira zvakanyanya chine nzvimbo yakakura pamusoro. Pamusoro payo pane maburi madiki ane hunhu hunodiwa pakugadzira catalysis, senge adsorption performance, surface activity, high thermal stability, nezvimwewo, saka inoshandiswa zvakanyanya se catalyst uye catalyst catalyst catalysts.
Oiri yealumina yakakamurwa kuita pressure swing oil inonyungudutsa muchimiro chewhite spheric porous particles. Alumina yakakamurwa ine saizi yakaenzana yeparticles, pamusoro payo pakatsetseka, ine simba guru remakanika, ine hygroscopicity yakasimba, haizvimbi kana kutsemuka mushure mekunwa mvura, uye inoramba isina kuchinja. Haina chepfu, haina hwema, uye hainyungudike mumvura uye mune ethanol.
Alumina
Hainyungudike mumvura uye inogona kunyungudika zvishoma nezvishoma musulfuric acid yakakora. Inogona kushandiswa kunatsa simbi yealuminium uye zvakare imhando yekugadzira zvimedu zvesimbi, porcelain, zvinhu zvinoramba kusimba uye matombo anokosha ekugadzira.
Alumina inoshandiswa semushonga unokwevera mvura, muchina unokonzeresa mvura uye muchina unokonzeresa mvura inonzi "activated alumina". Ine hunhu hwemaburi, kupararira kwakanyanya uye nzvimbo yakakura chaiyo. Inoshandiswa zvakanyanya mukurapa mvura, petrochemical, makemikari akanaka, zvipenyu uye mishonga.
Hunhu hwealumina
1. Nzvimbo yakakura chaiyo: alumina yakabatidzwa ine nzvimbo yakakwirira chaiyo. Nekudzora zvine mwero sisitimu yealumina, alumina yakabatidzwa ine nzvimbo chaiyo yepamusoro inosvika 360m2 / G inogona kugadzirwa. Alumina yakabatidzwa yakagadzirwa nekushandisa colloidal aluminum hydroxide yakasanganiswa neNaAlO2 sezvinhu zvisina kugadzirwa ine saizi diki yepore uye nzvimbo chaiyo yepamusoro inosvika 600m2 / g.
2. Chimiro chehukuru hwemaburi chinogadziriswa: Kazhinji, zvigadzirwa zvine saizi yepakati pemaburi zvinogona kugadzirwa nekubika nearuminiyamu hydroxide yakachena. Zvigadzirwa zvemaburi madiki zvinogona kugadzirwa nekugadzira activated alumina nearuminiyamu glue, nezvimwewo, nepo alumina yakakura inogona kugadzirwa nekuwedzera zvimwe zvinhu zvakasikwa, zvakaita seethylene glycol nefiber, mushure mekutsva.
3. Pamusoro payo pane acidic uye ine kugadzikana kwakanaka kwekupisa.
Basa realumina rakabatidzwa
Alumina yakakamurwa iri muboka remakemikari ealumina, ayo anonyanya kushandiswa seanosurbent, purifier yemvura, catalyst uye catalyst carrier. Alumina yakakamurwa ine simba rekusarudza kusurveta mvura mugasi, utsi hwemvura nezvimwe zvinwiwa. Mushure mekunge adsorption yazara, inogona kupiswa pa175-315. D egree. Adsorption uye reactivation zvinogona kuitwa kakawanda.
Pamusoro pekushandiswa se desiccant, inogona zvakare kutora mafuta anonhuhwirira kubva muokisijeni yakasvibiswa, hydrogen, carbon dioxide, gasi rechisikigo, nezvimwewo. Uye inogona kushandiswa se catalyst uye catalyst inotsigira uye sekutsigira chromatographic analysis.
Inogona kushandiswa semushonga unobvisa fluorinating mumvura yekunwa ine fluorine yakawanda (ine simba guru rekusunungura fluorinating), mushonga unobvisa fluorinating we alkanes dzinotenderera mukugadzirwa kwe alkylbenzene, mushonga unobvisa acid uye unovandudza mafuta e transformer, mushonga unoomesa we gasi muindasitiri inogadzira okisijeni, indasitiri yemachira neindasitiri yemagetsi, mushonga unoomesa wemhepo yezvishandiso otomatiki, uye mushonga unoomesa uye mushonga unochenesa mufetereza yemakemikari, kuomesa petrochemical nedzimwe nzvimbo.
