Abstract
Provided is a method for preparing a zeolite having a Si/Al ratio of at least 10 by interzeolite transformation in the absence of an organic structure directing agent. The method is more cost effective and less equipment intensive as it eliminates the costly organic structure directing agent and the waste treatment at the plant.
