Zeolite molecular sieves ine simba rekuparadzanisa mhedzisiro pane nitrogen uye oksijeni.Iyo ine maumbirwo uye hunhu hwekristaro, pamusoro isimbi yakasimba skeleton, uye mhango yemukati inogona kuita basa rekushambadza mamorekuru.Kune ma pores akabatana kune mumwe nemumwe pakati pemakomba, uye mamorekuru anopfuura nepakati pores.Nekuda kwehunhu hwakachena hwema pores, saizi yepore kugoverwa kwe molecular sieve yakanyanya kufanana.Masefa mamorekuru anosarudza adsorb mamorekuru zvichienderana nehukuru hwema pores mukati memakristaro, kureva, adsorb mamorekuru ehumwe saizi uku achidzinga mamorekuru ezvinhu zvakakura.
