The invention provides a crystalline aluminosilicate zeolite composition related to the family of ZSM-5 zeolites having formula, in terms of mole ratios of oxides, of [R2O, M'2/nO]w: {Al2O3]x {S1O2]y: [M''2/nO]z wherein 0.5<W/x<3, y/x is >20, 0<z/x<100 R is N containing cation, M' is Group IA metal and M'' is a metal selected from the rare earth metals, chromium, vanadium, molybdenum, indium, boron, mercury, tellurium, silver, ruthenium, platinum and palladium. The invention also provides a process for converting an organic charge with the zeolite and method for preparing it. |
