Abstract
A new porous zeolite, a method of making same and the use thereof in catalytic conversion of organic compounds. The new product has a composition, expressed in terms of moles of anhydrous oxides per 100 moles of silica as follows: (0-2.5)M.sub.2/n O:(0- 2.5)Al.sub.2 O.sub.3 :(100)SiO.sub.2 wherein M is at least one cation having a valence n and wherein the zeolite is characterized by the distinctive X-ray powder diffraction pattern as shown in Table 1 herein. The new zeolite is prepared from a reaction mixture comprising a source of silica, a source of organic compounds of Group VB, alkali metal cations, water and with or without a source of alumina.
