摘要： The present invention provides an essentially dry method for preparation of enhanced alumina powders. The first step involves rapid calcination of an aluminum compound to produce alumina powder. The alumina powder is mixed with solid ammonium carbonate and a small amount of water. This mixture heats itself although some external heat is helpful to produce ammonium aluminum hydroxycarbonate (dawsonite-type) NH4AlCO3(OH)2 upon curing which is then decomposed to produce enhanced alumina having a specific desired morphology and nano-sized dimensions.

摘要： A composite sorbent is formed which is the reaction product of a solid alkali metal carbonate, rehydratable alumina and water or an aqueous solution of a metal salt. The reaction between the components occurs while forming particulates followed by curing and activation. In one embodiment, the composite contains an appreciable amount of a Dawsonite-type hydroxycarbonate as a final product or as an intermediate in at least one of the production stages. The alkali metal in the sorbent exhibits a highly reactive and accessible state that is very favorable for various sorption applications. The sorbent is especially useful for removal of HCl and other acid contaminants from gas and liquid hydrocarbon streams. It combines a high capacity for the contaminants with a low reactivity towards the hydrocarbon components of the main stream.

摘要： 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., carboxylic acid, of the soluble carboxylic acid alkali metal salt.

摘要： A method is provided for removing HF and organic fluorides from fluid streams in which the fluoride species exist as impurities and, in particular, from hydrocarbon fluid streams containing no more than about 1.0% by weight total fluorides. The method consists of first contacting the fluid stream first with a nonpromoted alumina and then with an adsorbent consisting essentially of activated alumina that has been treated with a promoter material selected from the oxides and phosphates of alkali metals and alkaline earth metals, and mixtures thereof. This is preferably accomplished by providing a suitable absorber vessel charged with the adsorbent in a fixed bed, and then contacting the fluoride-contaminated fluid through the fixed bed.

摘要： The hydrothermal stability of transition aluminas used as adsorbents and catalyst carriers is improved through their treatment with a soluble silicon inorganic compound such as sodium silicate wherein the silicon compound is mixed with the alumina powder at the production stage of forming particulates by liquid addition. The silicon containing particulates are activated by heating at a temperature lower than 500° C. and treated, before or after the thermal activation, by a colloidal silica solution to produce a hydrothermally stable, low dust alumina. The total silica content of the final product is typically less than 5 mass-%.
