Alumino silica gel-AN

Tsanangudzo Pfupi

Kuonekwa kwealuminiumsilica geliri yero kana kuti jena iri pachena nekemikari molecular formula mSiO2 • nAl2O3.xH2O. Yakagadzikana makemikari zvinhu. Isingabatiki, isinganyungudika mune chero chinonyungudutsa kunze kwakasimba base uye hydrofluoric acid. Kuenzaniswa neakanaka porous silica gel, iyo adsorption yehumidity yakaderera yakafanana (yakadai seRH = 10%, RH = 20%), asi iyo adsorption kugona kwehunyoro hwepamusoro (seRH = 80%, RH = 90%) ndeye 6-10% yakakwirira kupfuura iyo yakatsetseka, iyo silika yakatsetseka uye 50 gel inogadzika. 150 ℃ yakakwirira kupfuura yakanaka porous silica gel Saka yakanyatsokodzera kushandiswa seyachinja tembiricha adsorption uye yekuparadzanisa mumiririri.

Inonyanya kushandiswa kupatsanura mwenje hydrocarbon kubva gasi rechisikigo, kuderedza dova rehydrocarbon, uye kugadzira gasi rechisikigo uye gasi, ukuwo, gasi rechisikigo rakawomeswa. Kana paine kudonhedza mvura mukuparadzanisa system, inoda nezve 20% (yereshi yehuremu) yeSi-Al-silica gel inodzivirira mvura sechidziviriro.

Ichi chigadzirwa chinogonawo kushandiswa sechinhu chakajairikadesiccant, catalyst uye mutakuri wayo, zvakare inogona kushandiswa sePSA, kunyanya yakakodzera kune yakanyanya tembiricha TSA.
