13X type molecular sieve, eo hape e tsejoang e le sodium X type molecular sieve, ke alkali metal aluminosilicate, e nang le motheo o itseng ebile e le oa sehlopha sa metheo e tiileng.3.64A e ka tlase ho 10A bakeng sa molek'hule efe kapa efe.
Boholo ba pore ea 13X sieve ea molek'hule ke 10A, 'me adsorption e kholo ho feta 3.64A le ka tlase ho 10A.E ka sebelisoa bakeng sa catalyst co-carrier, co-adsorption ea metsi le carbon dioxide, co-adsorption ea metsi le khase ea hydrogen sulfide, haholo-holo e sebelisetsoang ho omisa meriana le tsamaiso ea khatello ea moea.Ho na le mefuta e fapaneng ea likopo tsa litsebi.
