Alumino silica jel-AN

Sharaxaad Gaaban:

Muuqaalka aluminiumjel silicawaa huruud fudud ama cad cad oo leh qaacido kemikaad mSiO2 • nAl2O3.xH2O. Hantida kiimikada deggan. Gubasho la'aan, aan lagu milmi karin dareere kasta marka laga reebo saldhigga xooggan iyo hydrofluoric acid. Marka la barbar dhigo jel silica daloosan, awoodda adsorption ee qoyaan hooseeya waa la mid ah (sida RH = 10%, RH = 20%), laakiin awoodda adsorption ee huurka sare (sida RH = 80%, RH = 90%) waa 6-10% ka sarreeya jel silica daloolin ganaax, iyo xasiloonida kulaylka (350 ℃) waa 150 ℃ ka sarreeya jel silica dalool fiican. Sidaa darteed aad bay ugu habboon tahay in loo isticmaalo sida adsorption heerkulka variable iyo wakiilka kala soocidda.

Waxaa inta badan loo isticmaalaa in lagu kala saaro hydrocarbon iftiinka iyo gaaska dabiiciga ah, yaraynta barta sayaxa hydrocarbon, iyo soo saarida gaaska dabiiciga ah iyo gaaska, Dhanka kale, gaaska dabiiciga ah sidoo kale waa la qalajiyey. Haddii ay jirto dhibco biyo ah oo ku jira nidaamka kala-soocidda, waxay u baahan tahay qiyaastii 20% (miisaanka miisaanka) ee jelka Si-Al-silica ee biyaha u adkaysta sida lakabka ilaalinta.

Alaabtan waxa kale oo loo isticmaali karaa sida caadiga ahqallajiye, kicinta iyo qaadeheeda, sidoo kale waxaa loo isticmaali karaa PSA ahaan, gaar ahaan ku habboon heerkulka sare ee TSA.
