Alumino silica gel–AN

Tsananguro pfupi:

Kuonekwa kwearuminiyamugel resilicainopenya zvishoma yero kana chena ine fomura yemamorekuru yemakemikari mSiO2 • nAl2O3.xH2O. Hunhu hwemakemikari hwakagadzikana. Haitsvi, hainyungudike mune chero chinhu chinonyungudutsa kunze kwesimba rakasimba uye hydrofluoric acid. Kana ichienzaniswa ne silica gel ine porous yakanaka, kugona kwe adsorption kwehunyoro hwakaderera kwakafanana (senge RH = 10%, RH = 20%), asi kugona kwe adsorption kwehunyoro hwakanyanya (senge RH = 80%, RH = 90%) kwakakwira ne6-10% kupfuura kwe silica gel ine porous yakanaka, uye kugadzikana kwekupisa (350℃) kwakakwira ne150 ℃ kupfuura silica gel ine porous yakanaka. Saka yakakodzera kushandiswa se adsorption uye separation agent yekupisa kwakasiyana-siyana.

Ruzivo rweChigadzirwa

Matagi eChigadzirwa

Inonyanya kushandiswa kuparadzanisa hydrocarbon diki kubva kugasi rechisikigo, kuderedza dova rehydrocarbon, uye kugadzira gasi rechisikigo negasi, ukuwo gasi rechisikigo rinoomawo. Kana paine madonhwe emvura musystem yekuparadzanisa, inoda inenge 20% (huremu hwechiyero) yeSi-Al-silica gel isingapindi mvura sechikamu chekudzivirira.

Chigadzirwa ichi chinogonawo kushandiswa sechinhu chinowanzo shandiswamushonga wekubvisa vhudzi, catalyst uye chinotakura chayo, inogonawo kushandiswa sePSA, inonyanya kukodzera TSA inopisa zvakanyanya.
