<p>Zeolite based material and a method for making the zeolite, comprising a zeolite having a silica/alumina ratio of at least 300 and a surface area of 250 m2/g and no greater than about 20 parts, by weight, of a silica binder. The combination of properties this zeolite based material exhibits includes the following: (1) a modulus of rupture of at least 1500 psi; (2) a surface area of at least 100 m2/g; (3) a coefficient of thermal expansion of less than about +/-10 ppm/°C; and, (4) a thermal shock resistance of at least 850 °C. The zeolite-based material can include a third component, specifically a gamma alumina having a specific surface area of greater than 100 m2/g.</p> |
