3Sefe ea molek'hule

3Sieve ea molek'hule ke alkali metal aluminate, ka linako tse ling e boetse e bitsoa 3A zeolite molecular sieve.

Lebitso la Senyesemane: 3A Molecular Sieve
Silika / aluminium karo-karolelano: SiO2/ Al2O3≈2
Boholo bo sebetsang ba pore: hoo e ka bang 3A (1A = 0.1nm)

Molao-motheo oa ts'ebetso oa sieve ea molek'hule o amana haholo le boholo ba pore ea sieve ea molek'hule, ka ho latellana 0.3nm/0.4nm/0.5nm, li ka khantša limolek'hule tsa khase tseo bophara ba tsona ba molek'hule bo leng nyane ho feta boholo ba pore, le boholo ba pore, e kholoanyane matla a ho bapatsa. Boholo ba lesoba le fapane, 'me lintho tse tlhotliloeng li fapane. Ka mantsoe a bonolo, 3a sieve ea molek'hule e ka bapa limolek'hule feela ka tlase ho 0.3nm.

3Sieve ea molek'hule e na le boholo ba pore ea 3A, e sebelisoang haholo ho khahla metsi, 'me ha e khahlise molek'hule ofe kapa ofe ka bophara bo fetang 3A. Ho ea ka litšoaneleho tsa ts'ebeliso ea indasteri, sieve ea limolek'hule e na le lebelo le potlakileng la adsorption, linako tsa nchafatso, matla a sithabetsang le bokhoni ba ho thibela tšilafalo, e ntlafatsang ts'ebeliso e ntle ea sieve ea limolek'hule le ho lelefatsa bophelo ba ts'ebeletso ea sieve ea limolek'hule. Ke sesebelisoa se hlokahalang sa adsorption bakeng sa ho omisa ho tebileng, ho hloekisoa le polymerization ea karolo ea metsi a khase indastering ea peterole le ea lik'hemik'hale.
