Abstract

There is provided a pillared, layered crystalline oxide material and a method for making this material. This material may be prepared by intercepting a swellable layered oxide before calcination. The intercepted material is swollen and pillared. If the material is not intercepted in this manner, it is transformed into a zeolite by calcination. The pillared material may have a large degree of catalytic activity, and it may have rather porous layers.
