<p>Microporous crystalline ferrosilicate has the formula: aM(2/n)O:(Al(x)Fe(1-x))2O3;BSiO2, where M=cation of valence n, a=0-2.0, b=3-100, x=0-0.98 and has a characteristic X-ray powder diffraction pattern contg. d spacings (as below). Compsn. is formed by maintaining the following molar oxide compsn. at 100-200 deg.C under autogenous pressure: 0-10 R2O:1-15 M(2/n)O:(Al(x)Fe(1-x))2O3:10-200 SiO2:200-1000 H2O, where R=organic templating agent.</p> |
