Abstract
A new porous silico-crystal, designated as ZSM-48, 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: (0.05 to 5) N.sub.2 O: (0.1 to 10)M.sub.2 /.sub.n O: (0 to 4)Al.sub.2 O.sub.3 : (100)SiO.sub.2 wherein M is at least one cation having a valence n, N is a mixture of C.sub.2 -C.sub.12 alkylamine and more preferably of C.sub.3 -C.sub.5 tetramethyl ammonium compound, and wherein the zeolite is characterized by the distinctive X-ray powder diffraction pattern shown in Table I.
