The Structural Properties OfActivated Alumina
Activated alumina ine hunhu hwehukuru adsorption kugona, hombe chaiyo yenzvimbo, simba repamusoro, uye yakanaka kugadzikana kwekupisa. substance. Iyo ine hukama hwakasimba, isiri-chepfu, isina-corrosive inoshanda desiccant, uye yayo static kugona kwakakwirira. Inoshandiswa se adsorbent, desiccant, catalyst uye mutakuri mune dzakawanda maitiro maitiro akadai se petroleum, kemikari fetiraiza uye indasitiri yemakemikari.
Activated alumina ndeimwe yeanonyanya kushandiswa inorganic makemikari zvigadzirwa munyika. Izvo zvinhu zvealumina yakagadziriswa zvinotsanangurwa pasi apa: Activated alumina ine kugadzikana kwakanaka uye yakakodzera se desiccant, catalyst carrier, fluorine kubvisa agent, pressure swing adsorbent, inokosha yekuzvarwa patsva ye hydrogen peroxide, nezvimwewo.
Activated alumina inoshandiswa se desiccant, inonyanya kushandiswa mumaindasitiri emhepo yekuomesa midziyo yekuomesa, mhepo yekuomesa midziyo ine simba rekushanda, kazhinji pazasi 0.8Mpa, iyo inoda iyo activated alumina reshiyo kuti ive nesimba rakanaka remagetsi, kana simba remuchina rakaderera, zviri nyore kuita upfu, hupfu uye mvura musanganiswa unovhara zvakananga pombi yemidziyo, saka, Chiratidzo chakakosha chinoshandiswa seyakaomeswa nemhepo inomiswa matangi maviri, matangi maviri anoshanda zvakachinjana, ari chaizvo adsorption saturation → analytic cycle process, desiccant inonyanya kushambadza mvura, asi pasi pemamiriro ekushanda echokwadi, mhepo yekuomesa midziyo yekumisikidza mhepo ichava nemafuta, ngura uye kumwe kusvibiswa, Izvi zvinhu zvinokanganisa zvakananga hupenyu hwebasa re activated alumina adsorbent, nekuti porousation adsorbent adsorbent ndeye activated adsorbent. mvura, mafuta adsorption zvakare yakanaka kwazvo, asi mafuta achaita plug yakananga activated alumina adsorption pore, kuitira kuti kurasikirwa kwemaitiro adsorption, kune ngura, ngura mumvura, yakabatanidzwa pamusoro peiyo activated alumina, Ichaita activated alumina yakananga kurasikirwa nebasa, saka mu activated alumina se desiccant kushandiswa, edza kudzivisa kusangana nemafuta emushonga Hupenyu hwemakore 1 ~ 3, iko kushandiswa chaiko kuchave kuomesa gasi dova kuti usarudze kana kutsiva activated alumina. Iyo tembiricha yekuvandudza yealumina yakagadziriswa iri pakati pe180 ~ 350 ℃. Kazhinji, iyo yakagadziriswa alumina tower tembiricha inokwira kusvika 280 ℃ kwe4 maawa. Activated alumina inoshandiswa semvura yekurapa mumiririri, uye aluminium sulfate mhinduro inoshandiswa seyakagadziridza. Mushonga wekugadzirisa aluminium sulfate regenerator ndeye 2 ~ 3%, iyo yakagadziriswa alumina mushure mekudsorption saturation inoiswa mualuminium sulfate solution soaking, kurasa mhinduro, geza nemvura yakachena 3 ~ 5 nguva. Mushure mekushandiswa kwenguva refu, iyo yakagadziriswa alumina pamusoro ine yellowish brown uye iyo defluorination mhedzisiro inoderedzwa, iyo inokonzerwa nekushambadza kwetsvina. Inogona kurapwa ne 3% hydrochloric acid kwekanguva kamwechete uye yobva yadzorerwa nenzira iri pamusoro.
