Methods of making zeolite beta materials

Abstract

According to one or more embodiments, a zeolite beta material may be made by a method that may include adding a parent zeolite beta in a basic solution to form a basic zeolite beta suspension, adding water to the basic zeolite beta suspension to form a dilute basic zeolite beta suspension, hydrothermally treating the dilute basic zeolite beta suspension to form a hydrothermally treated mixture, and separating from the hydrothermally treated mixture a solid zeolite beta material consisting essentially of polymorph-A and polymorph-B. The molar ratio of polymorph-A to polymorph-B of the solid zeolite beta material may be greater than molar ratio of polymorph-A to polymorph-B of the parent zeolite beta.
