Abstract

Crystalline mordenite is prepared by dispersing an amorphous alkali-metal aluminosilicate in water, adjusting the pH of the dispersion to 11.0-13.3, heating the dispersion under autogenous pressure at 200-375 DEG C., the aluminosilicate having molar ratios of SiO2/Al2O3 of 9.0-13.5 and of alkali metal oxide to alumina of 0.4-1.6. The alkali metal aluminosilicate may be obtained by reaction between an alkali metal silicate solution (e.g sodium silicate) and an inorganic aluminium salt solution (e.g. aluminium sulphate, chloride or nitrate, or an alum) at room temperature with stirring, the reaction mixture preferably having molar ratios of SiO2/Al2O3 of at least 10 and of SiO2/Na2O of 2-3.5. Alternatively, the aluminosilicate may be prepared by the method claimed in Specification 753,052. At least some of the sodium ions in a crystalline sodium mordenite prepared by the method of the invention may be replaced by other alkali metal ions, alkaline earth metal ions, zinc or hydrogen ions, using ion exchange techniques.ALSO:A synthetic mordenite produced by a hydrothermal process (see Abridgment Division C1) is used as an ion-exchange in a column operated at 200 DEG C.
