ABSTRACT:
A porous crystalline composition having a molar composition as follows: YO2:m X2O3:n ZO, wherein Y is a tetravalent element selected from the group consisting of silicon, germanium, tin, titanium and combinations thereof, X is a trivalent element selected from the group consisting of aluminum, gallium, boron, iron and combinations thereof, Z is a divalent element selected from the group consisting of magnesium, zinc, cobalt, manganese, nickel and combinations thereof, m is between about 0 and about 0.5, n is between about 0 and about 0.5; and the composition has an x-ray diffraction pattern which distinguishes it from the materials. A process for making the composition, and a process using the composition to treat an organic compound are also provided.
