Abstract
This invention relates to novel zeolitic compositions having transition metals as well as aluminum and silicon in the framework tetrahedral positions. The composition has a structure similar to mazzite type zeolites. The invention also involves a process of preparation in which at least one transition metal is directly synthesized into the product.
