Abstract

1450411 Zeolites IMPERIAL CHEMICAL INDUSTRIES Ltd 17 Jan 1974 [26 Jan 1973] 4130/73 Heading C1A Crystalline synthetic faujasite of formula where x=0À6-1À0, y=0-0À4, z=0-0À4, x+ y + z= 1 and R is NH 4 <SP>+</SP> and/or H<SP>+</SP> are made by thoroughly mixing, in water at not over 95‹ C. and in proportions required to produce the faujasite, (1) a silica source comprising an alkali metal silicate, (2) an alkali metal aluminate and (3) an acid reacting compound insufficient in quantity to neutralize the alkali metal compounds, and crystallizing faujasite therefrom, the manner of mixing being such that the pH does not fall below 7 during mixing. The major part of the silica source may be waterglass having SiO 2 /M 2 O ratio 2-4 : 1 where M is NaŒK, the remainder being active sodium silicate and/or active silica. The acid-reacting compound may be aluminium sulphate, nitrate and/or chloride. A preferred mixing procedure is to mix the major silica source and the active silica and/or active silicate with water and then add the sodium aluminate solution with vigorous agitation at below 50‹ C. When thoroughly mixed, aluminium sulphate is added as a liquid. Vigorous mixing is continued until homogenization is achieved. Then the temperature is raised to the desired crystallization condition viz 50‹ to 120‹ C., and the crystallization is carried out, preferably with agitation, until faujasite is obtained. The products obtained are synthetic faujasites having high crystallinity as shown by X-ray diffraction techniques. They may be ion exchanged with cations of Groups IA, IB, II and III (including rare earths), Group VIIA, Group VIII (including noble metals) to give catalysts, e.g. for gas oil cracking. The ion exchanged forms can be incorporated, if desired, with diluents, e.g. kaolinic clays, bentonites, fuller's earth.
