ABSTRACT:
A calcined and shaped alumina, exhibiting a stabilized, high pore volume and a low surace area together with high strength, is made from an alumina, such as pseudoboehmite or chi-rho-eta alumina or mixtures of different alumina species. The stabilized product exhibits a total porosity of at least about 0.4 cc/g, a surface area within the range of about 2-20 m.sup.2 /g. The porosity is stabilized by treatment of the alumina, prior to calcination, with a combination of silica and an inorganic fluoride. The stabilized alumina product can be readily utilized as an adsorbent or a catalyst support, particularly in applications where the catalyst is subjected to high temperatures.
