Molecular sieve 3A, nke a makwaara dị ka molecular sieve KA, nke nwere oghere nke ihe dị ka 3 angstroms, nwere ike iji mee ihe maka ihicha gas na mmiri mmiri yana akpịrị ịkpọ nkụ nke hydrocarbons. A na-ejikwa ya n'ọtụtụ ebe maka ikpocha mmanụ ọkụ, gas gbawara agbawa, ethylene, propylene na gas eke.
Ụkpụrụ na-arụ ọrụ nke sieves molekụla metụtara nke ọma na nha nke sieves molecular, nke bụ 0.3nm/0.4nm/0.5nm n'otu n'otu. Ha nwere ike ịgbanye ụmụ irighiri gas nke dayameta molekụla ha dị obere karịa nha pore. Ka oke nha nke pore buru ibu, ka ikike mgbasa ozi na-abawanye. Ogo pore dị iche iche, ihe ndị a na-enyocha na nkewa dị iche iche dịkwa iche. N'okwu dị mfe, sieve molekụla 3a nwere ike ịgbasa ụmụ irighiri ihe dị n'okpuru 0.3nm, sieve molecular 4a, ụmụ irighiri ihe a na-ekesa ga-enwerịrị ihe na-erughị 0.4nm, na sieve molecular 5a bụ otu ihe ahụ. Mgbe ejiri ya dị ka onye na-ekpochapụ ihe, sieve molecular nwere ike ịmịkọrọ ihe ruru 22% nke ịdị arọ ya na mmiri.
