Abstract: A method of producing activated alumina bodies having alkali or alkaline earth metal compounds incorporated therein, the bodies suitable for adsorption and having increased capacity for adsorption of gases and the like. The method comprises providing a source of activated alumina powder and further providing an aqueous solution having an alkali or alkaline earth metal hydroxide and a water soluble alkali or alkaline earth metal salt of an organic compound dissolved therein. The activated alumina powder is formed into bodies which are treated with the aqueous solution to provide alumina bodies having alkali or alkaline earth metal compounds incorporated therein. The alumina bodies are heated for purposes of activation to provide said activated alumina bodies capable of having increased adsorption capacity.

Abstract: A method of preparing an alumina-based bodies suitable for use as an adsorbent or catalyst, the method comprising providing a source of activated alumina powder for forming into bodies and providing an aqueous solution containing at least two different alkali metals, at least one alkali metal derived from a soluble carboxylic acid alkali metal salt. As said powder is formed into said bodies, the bodies are contacted or sprayed with the aqueous solution to provide composite bodies containing the alumina powder and the alkali metals and the soluble carboxylic acid alkali metal salt. Alternatively, the alumina bodies may be formed first and then contacted, e.g., soaked in the aqueous solution. Or, a viscous slurry of the activated alumina powder and the aqueous solution may be made. The viscous slurry may be made into bodies by extrusion or by the oil drop method. Thereafter, the bodies are thermally treated to activate alumina therein and remove or decompose the organic part, e.g.

Abstract: A method of producing activated alumina bodies having alkali or alkaline earth metal compounds incorporated therein, the bodies having increased surface area and crush resistance, the method comprising providing a source of activated alumina powder and an aqueous solution having an alkali or alkaline metal hydroxide dissolved therein, the solution having a pH in the range of 12 to 13.5. The activated alumina powder is formed into bodies, and are treated with the aqueous solution to form alumina bodies having alkali or alkaline earth metal compounds incorporated therein. The alumina bodies are heated to provide activated alumina bodies having increased surface area and crush resistance.

Abstract: A catalyst useful in the aromatization of light paraffins and other hydrocarbons conversion reactions, formed by preparing an intimate mechanical mixture of a gallium-containing species, such as Ga.sub.2 O.sub.3, with a zeolite having a pore mouth comprising 10 oxygen atoms, such as ZSM-5, preferably followed by treatment with a reducing agent, such as hydrogen.
