Molecular sieve, its preparation and application thereof

Abstract:

The present invention relates to a molecular sieve, particularly to an ultra-macroporous molecular sieve. The present invention also relates to a process for the preparation of the molecular sieve and to its application as an adsorbent, a catalyst, or the like. The molecular sieve has a unique X-ray diffraction pattern and a unique crystal particle morphology. The molecular sieve can be produced by using a compound represented by the following formula (I), ##STR00001## wherein the definition of each group and value is the same as that provided in the specification, as an organic template. The molecular sieve is capable of adsorbing more/larger molecules, thereby exhibiting excellent adsorptive/catalytic properties.
