摘要：
A process for isomerising xylene using a new family of related crystalline aluminosilicate zeolites has been developed. These zeolites are represented by the empirical formula: Mmn+Rrp+Al(1−x)ExSiyOz where M is an alkali or alkaline earth metal such as lithium and strontium, R is a nitrogen containing organic cation such as tetramethyl-ammonium and E is a framework element such as gallium.
