Molecular Sieve Adsorbents
From a narrow sens, the molecular sieve is a crystalline silicate or silicoaluminate, formed by a silicon-oxygen tetrahedron or an aluminum-oxygen tetrahedron connected by an oxygen-bridge bond. From the broad sense, there are regular and uniform pores in the structure, the aperture of which is an order of magnitude of the size of the molecule. It only allows molecules with a diameter smaller than the aperture to enter, so the molecules in the mixture can be screened by…
