Abstract
Crystalline aluminosilicates such as zeolite beta may be readily dealuminated using organic sulfonic acids such as methanesulfonic acid to provide useful catalysts or catalyst precursors. A high degree of aluminum removal with minimal loss of crystallinity is possible even when an organic template is not present in the starting aluminosilicate.
