Kev piav qhia

Cov tsos ntawm txhuas silica gel yog daj daj lossis dawb pob tshab nrog cov tshuaj molecular mis mSiO₂-nAlO₃xHO Cov khoom ruaj khov. Piv nrog cov ntxeem tau zoo silica gel, lub peev xwm adsorption ntawm cov av qis yog qhov zoo sib xws (xws li RH=10%, RH=20}%), tab sis lub peev xwm adsorption ntawm cov av noo siab (xws li RH {{2}). }% RH=90%) yog 6-10% siab dua li ntawm cov ntxeem tau zoo silica gel, thiab cov thermal stability (350'C) yog 150'C siab dua cov ntxeem tau zoo silica gel. Yog li nws yog qhov tsim nyog siv los ua qhov sib txawv ntawm qhov kub thiab txias adsorption thiab cais tus neeg sawv cev.

Daim ntawv thov

silica raws li catalyst cab kuj yog tsuas yog siv los cais lub teeb hydrocarbon los ntawm natural gas, txo qhov dew point ntawm hydrocarbon, thiab tsim cov roj av roj, tib lub sij hawm, cov roj ntuj kuj qhuav. Yog tias cov tee dej muaj nyob rau hauv qhov kev sib cais, kwv yees li 20% (qhov hnyav piv) ntawm cov dej-resistant Si-Al-silica gel yuav tsum tau muab ntxiv ua txheej txheej tiv thaiv.

Silica raws li catalyst carriers kuj tseem siv tau los ua ib qho desiccant, catalystand nws cov cab kuj, kuj siv tau raws li PSA, tshwj xeeb tshaj yog haum rau kub TSA.
