ABSTRACT:
A large crystal zeolite Beta having a broad range of silica-to-alumina ratios, i.e. 20.fwdarw.1000, is synthesized with a chelating agent, exemplified by a tertiary alkanolamine such as triethanolamine in the synthesis mixture along with organic directing agents such as tetraethylammonium hydroxide, tetraethylammonium bromide and tetraethylammonium fluoride. The highly silicious zeolite Beta is produced from a silica source comprising precipitated silica and high purity, high silica starter seeds.
