AL2O3 Daawaynta Gaaska Qashinka Dabiiciga ah
AL2O3 daawaynta gaaska qashinka dabiiciga ah waxa loo istcimaalaa qalab kaalmeeya biraha firfircoon ee kiciya si loo daweeyo gaaska wasakhda dabiiciga ah, ee maaha kataliyad gooni ah. Waxay siisaa aag weyn oo dusha sare ah iyo qaab-dhismeedka dalool ee biraha firfircoon sida nikkel (N i), platinum (Pt), iyo rhodium (Rh) in lagu kala firdhiyo, taasoo kordhinaysa waxtarkooda falcelinta sida oksaydhka catalytic iyo ka saarida daamurka gaaska qashinka. Tusaale ahaan, kiciyayaasha Ni/Al2O3 waxa loo isticmaalaa saarista daamurka, halka Pt/Al2O3 loo isticmaalo deoxygenation gaaska qashin-qubka.

Sida Al2O3 u shaqeyso
- Taageerada biraha firfircoon:Al2O3 waxa ay bixisaa xasilloon, sare - dusha sare - taageer aag biraha firfircoon sida nikkel (Ni), platinum (Pt), iyo rhodium (Rh). Tani waxay u ogolaaneysaa birta firfircoon in loo kala firdhiyo sida nanoparticles, kordhinta tirada goobaha firfircoon.
- Porosity:Qaab dhismeedkeeda mesoporous wuxuu u oggolaanayaa wasakhowga gaaska inay galaan oo ku jiraan daloollada muddo dheer, taasoo kordhinaysa heerka falcelinta.
- Goobaha aysiidhka:Al2O3 waxay leedahay goobo aysiidh ah oo gacan ka geysan kara dhaqdhaqaaqa kicinta, sida dillaaca hydrocarbons.
Tusaalooyinka AL2O3 kicinta daaweynta qashinka dabiiciga ah
- Ni/Al2O3 kiciyaasha:Loo isticmaalo in daamurka lagaga saaro gaaska wasakhda ah ee la soo saaro inta lagu jiro gaasta noole. Waxay gaari karaan hufnaan ka saarista daamurka sare, inta badan in ka badan 99%.
- Pt/Al2O3 kiciyaasha:Waxa loo isticmaalaa deoxygenation-ka gaaska qashin-qubka iyada oo meesha laga saarayo isku-dhisyada organic-ga ah ee kacsan (VOCs). Samaynta kookaha waxay ka dhici kartaa VOC-yada, laakiin kicinta ayaa weli ah mid wax ku ool ah xitaa iyada oo la isku qurxiyo.
- Rh/Al2O3 kicinta:Loo isticmaalo ka saarida wasakhaha sida polycyclic aromatic hydrocarbons (PAHs) ee gubi qashinka. Joogitaanka wasakhaha kale waxay saameyn kartaa waxqabadka, sidaas darteed wax-qabad ayaa laga yaabaa in wax laga beddelo (tusaale, lagu daro sodium) si loo hagaajiyo xasilloonida.
- Fe2O3/Al2O3 kicinta:Loo isticmaalo gubashada kicinta si loogu daweeyo gaaska qashinka.
