Abstract
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) N2O:(0.1 to 10)M2/nO:(0 to 4) Al2O3:(100) SiO2 wherein M is at least one cation having a valence n, N is a mixture of C2-C12 alkylamine and more preferably of C3-C5 tetramethyl ammonium compound, and wherein the zeolite is characterized by the distinctive x-ray powder diffraction pattern shown in Table I.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
120 words
A process for effecting catalytic conversion of an organic charge which comprises contacting said charge under catalytic conversion conditions with a catalyst comprising the porous silico-crystal ZSM- 48 having a composition expressed in terms of moles of anhydrous oxides, per 100 moles of silica, as follows: (0.5 to 5)N.sub.2 O:(0.1 to 10)M.sub.2 /.sub.x 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 a C 2 -C 12 alkylamine compound and tetramethylammonium compound, and wherein said crystal is characterized by the X-ray diffraction pattern whose values are set forth in Table I of the specification and which exhibits a singlet line within the range of 11.8 0.2 Angstrom units.
Claim 2
Dependent Claim
120 words
A process for effecting catalytic conversion of an organic charge which comprises contacting said charge under catalytic conversion conditions with a catalyst comprising the porous silico-crystal ZSM- 48 having a composition expressed in terms of moles of anhydrous oxides, per 100 moles of silica, as follows: (0.5 to 5)N.sub.2 O:(0.1 to 10)M.sub.2 /.sub.x 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 a C 2 -C 12 alkylamine compound and tetramethylammonium compound, and wherein said crystal is characterized by the X-ray diffraction pattern whose values are set forth in Table I of the specification and which exhibits a singlet line within the range of 11.8 0.2 Angstrom units.
Claim 3
Dependent Claim
40 words
