I-Zeolite i-molecular sieves inesakhiwo esikhethekileyo sekristale esiqhelekileyo, ngasinye sinesakhiwo se-pore sobukhulu obuthile kunye nokuma, kwaye sinommandla omkhulu ocacileyo. Uninzi lwe-zeolite i-molecular sieves inamaziko e-asidi eqinile kumphezulu, kwaye kukho intsimi ye-Coulomb eqinile kwi-crystal pores ye-polarization. Ezi mpawu ziyenza ibe yi-catalyst egqwesileyo. Iimpendulo ze-Heterogeneous catalytics zenziwa kwii-catalysts eziqinileyo, kwaye umsebenzi we-catalytic unxulumene nobukhulu be-crystal pores ye-catalyst. Xa i-zeolite ye-molecular sieve isetyenziswe njenge-catalyst okanye i-catalyst carrier, inkqubela phambili ye-catalytic reaction ilawulwa yi-pore ye-zeolite ye-molecular sieve. Ubungakanani kunye nokuma kwe-crystal pores kunye ne-pores inokudlala indima ekhethiweyo kwi-catalytic reaction. Phantsi kweemeko zokusabela ngokubanzi, iisefu zemolekyuli ze-zeolite zidlala indima ephambili kwicala lokusabela kwaye zibonisa ukusebenza kwe-catalytic yokukhetha imilo. Lo msebenzi wenza ukuba i-zeolite i-molecular sieves ibe yinto entsha ye-catalytic enamandla anamandla.
