Zeolite molecular sieves ine simba rekuparadzanisa rakasimba pane nitrogen uye oksijeni.Iyo ine maumbirwo uye hunhu hwekristaro, iyo pamusoro isimbi yakasimba skeleton, uye maburi emukati anogona kuita basa rekushambadza mamorekuru.Kune pores akabatana kune mumwe nemumwe pakati pemakomba, uye mamorekuru anopfuura nepakati pores.Nekuda kwehunhu hwakachena hwema pores, saizi yepore kugovera kwe molecular sieve yakanyanya kufanana.Masefa mamorekuru anosarudza adsorb mamorekuru zvichienderana nehukuru hwemapores mukati memakristasi awo, kureva, adsorb mamorekuru ehumwe saizi uku achidzinga mamorekuru ezvinhu zvakakura.
