Abstract
A silica-alumina material, its preparation and application thereof are provided. The silica-alumina material has a SiO/AlOmolar ratio of 0.8-1.5, and has a lamellar structure with an average length of 0.5-2 μm and an average thickness of 30-80 nm, and its calcined form has a specific XRD pattern. The silica-alumina material has the characteristics of large pore volume, two-stage gradient pore channels of mesopores and macropores, as well as high B acid content as in molecular sieve, and shows crystal characteristics of a molecular sieve, and low impurity content, and thus is suitable for use as a carrier for catalytic materials, particularly a carrier for heavy oil hydrogenation catalysts.
