摘要： A method is provided for production of low dust adsorbents and catalysts. A thin layer of metal oxide derived from a colloidal solution of the oxide is deposited on the adsorbent or catalyst particle, which greatly improves the physical properties of the particle with regards to attrition and dust formation while retaining the adsorbent and catalytic properties of the particle. The method is applicable to a variety of porous refractory oxides. For example, treatment with colloidal silica improves greatly the physical stability of alumina adsorbents.

摘要： Novel, hollow, low-density agglomerates for use in sealed insulating glass windows to adsorb water vapor, and optionally organic materials, present in the cavity between the two glazings. These agglomerates provide sufficient but not excessive amounts of zeolitic and other adsorbents when used to fill all portions of the spacer tube located at the peripheral sides of the double glazed unit, thereby greatly facilitating the filling of such spacer tubes and the fabrication of the overall unit.

摘要： Molecular sieve agglomerates that can have improved physical and chemical properties are prepared by methods which comprise contacting the agglomerates with an alkali metal silicate solution. Molecular sieve agglomerates which comprise binders such as kaolin can additionally be contacted with an alkali hydroxide solution to convert the kaolin to Zeolite A prior to contacting the agglomerates with the alkali metal silicate solution to further improve properties. The molecular sieve agglomerates prepared according to the present invention are suitable for use as refrigerant desiccants.

摘要： This invention involves the use of a more effective adsorbent to dehydrate ethanol. The most common use for the ethanol is an additive to gasoline. The preferred adsorbent is a type 3A adsorbent that has been ion exchanged with potassium at a level of about 0.6. Surprisingly, this adsorbent has a significantly improved resistance to damage by water upset events.

摘要： Difluoromethane (R-32) is of current interest as a partial replacement for chlorodifluoromethane (R-22) refrigerant heretofore widely used in vapor compression refrigeration systems. R-32 has, however, proved to be more reactive than is desirable with the zeolite A adsorbent-desiccant compositions used in such systems to prevent corrosion and freeze-up problems. The potassium cation form of a zeolite A molecular sieve—with at least 60 percent of the sodium cations replaced with potassium ions, agglomerated with a clay binder, and pore-reduced to essentially exclude the adsorption of R-32 having essentially no reactivity with difluoromethane, and having a surface ratio of silicon to aluminum of less than about 1.7 mol/mol as determined by X-ray photoelectron spectroscopy—has been found to be an effective desiccant for refrigerants comprising difluoromethane.
