摘要： Methods for limiting bleed-through of aqueous catalyst solutions in ceramic articles are described herein. The methods include applying a hydrophobic cellulose derivative, such as ethylcellulose, to an exterior surface of a fired porous ceramic article. The aqueous catalyst solution is applied to the fired porous ceramic article, such that the hydrophobic cellulose derivative limits bleed-through of the aqueous catalyst solution through at least a portion of the ceramic article. Ceramic articles with skins that limit bleed-through of aqueous catalyst solutions are also described herein.

摘要： A silica-alumina material, its preparation and application thereof are provided. The silica-alumina material has a SiO2/Al2O3 molar 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.
