Modified EU-1 zeolite, contains silicon (Si) and an element (T) (where, T = Al, Fe, Ga or B). The atomic Si/T ratio is \- 10, which is larger than the starting zeolite Si/T ratio by a difference \- 10%. Also claimed is the production of a zeolite, in which the modified (EU-1) zeolite is obtained by thermal treatment followed by treatment with a chemically dealuminised compound, e.g. aluminium hexafluorosilicate, SiCl4, and ethylene diamine tetraacetic acid, in sodium (Na) or di-Na form. |
