Pentasil zeolites agglomerated in the form of hollow spheres

摘要

Abstract of the Disclosure: Pentasil zeolites agglomerated in the form of hollow spheres and having a particle size of from 5 to 200 micron are prepared by treating a mixture of an aqueous alkylenediamine, alkylenetriamine and/or alkylenetetramine, silica and an aluminum, boron and/or titanium salt at from 20 DEG to 100 DEG C., then crystallizing the product at from 110 DEG to 200 DEG C. and from 0.01 to 50 bar and calcining it at from 400 DEG to 650 DEG C., and said zeolites are used as catalysts and/or adsorbents.
