3A 4A 5A 13X Molecular Sieve Zeolite
Molecular sieve(tseem hu ua hluavtaws zeolite) yog aluminosilicate microporous siv lead ua. Nws yog cov qauv pob txha yooj yim tsim los ntawm silicon-oxygen thiab txhuas-oxygen tetrahedra, thiab hlau cations (xws li Na plus, K ntxiv, Ca2 ntxiv, thiab lwm yam) muaj nyob rau hauv cov siv lead ua lattice kom sib npaug cov nqi tsis zoo hauv cov siv lead ua. Cov hom molecular sieves feem ntau muab faib ua: A hom, X hom, Y hom thiab lwm yam raws li lawv cov qauv siv lead ua.
Lub ntsiab tseem ceeb ntawm A-hom molecular sieve yog aluminosilicate, uas yog tsim los ntawm silicon-oxygen thiab txhuas-oxygen tetrahedron los ua ib qho LTA-hom pob txha qauv, thiab lub ntsiab siv lead ua pore yog yim-ntiv nplhaib qauv. Lub ntsiab siv lead ua pore txoj kab uas hla yog 4A (1A=0.1nm), uas yog hu ua 4A hom (tseem hu ua nano-A hom) molecular sieve; pauv Na ntxiv rau hauv 4A molecular sieve nrog Ca2 ntxiv rau tsim 5A pore loj, uas yog 5A hom (tseem hu ua calcium hom). Ib hom) molecular sieve; pauv Na plus ntawm 4A molecular sieve nrog K ntxiv rau tsim pore loj ntawm 3A, uas yog 3A hom (tseem hu ua potassium A hom) molecular sieve.
Lub ntsiab tseem ceeb ntawm X-hom molecular sieve yog aluminosilicate, uas yog tsim los ntawm silicon-oxygen thiab txhuas-oxygen tetrahedron. Cov qauv siv lead ua yog sib txawv (qhov piv ntawm silicon rau txhuas yog qhov sib txawv), tsim cov molecular sieve siv lead ua nrog lub pore loj ntawm 9-10A, uas yog hu ua 13X (tseem hu ua sodium X type) molecular sieve; Txau Na plus nyob rau hauv 13X molecular sieve nrog Ca2 ntxiv rau tsim ib tug molecular sieve nrog ib tug pore loj ntawm 8-9Ib Crystal, hu ua 10X (tseem hu ua calcium X hom) molecular sieve.
