    摘要: A process for the production of an alkaline earth metal, aluminum-containing spinel/clay composition comprises: (a) combining (1) an acidic, aluminum-containing composition in which the aluminum is present in a positively charged species, and (2) a basic, alkaline earth metal-containing composition to form a gel mixture; (b) mixing the gel with kaolin clay to form a co-gel; and (c) calcining the co-gel mixture to form the alkaline earth metal, aluminum-containing spinel composition in a clay matrix. Alkaline earth metal, aluminum-containing spinel/clays having both high surface areas and very high attrition resistance, and processes for using spinel/clay compositions, e.g., as sulfur oxide and nitrogen oxide removal agent, are also disclosed.

    摘要: Die Oxidation von Schwefeldioxid zu Schwefeltrioxid wird in Gegenwart von Katalysatoren durchgeführt, die aus einem Träger auf Basis von Kieselsäure und darauf aufgebrachter aktiver Substanz, enthaltend Vanadium- und Alkalimetallverbindungen, besteht. Zwecks Erhöhung der Staubaufnahmefähigkeit einer Katalysatorschüttung weist der Katalysator einen sternförmigen Querschnitt mit 4 bis 6 Zacken auf.
