Molecular sieve SCM-14, a preparation process and use thereof

Abstract:

The invention relates to a molecular sieve SCM-14, a preparation process and use thereof. The molecular sieve has a schematic chemical composition of a formula of "SiO.sub.2.1/nGeO.sub.2" or a formula of "kF.mQ.SiO.sub.2.1/nGeO.sub.2.pH.sub.2O", wherein the molar ratio of silicon to germanium, n, satisfies n.ltoreq.30, and other values and symbols are defined in the specification. The molecular sieve has unique XRD diffraction data and can be used as an adsorbent or a catalyst.
