Abstract: A gas stream containing nitrous oxide and ammonia is contacted with a catalyst composition containing a zeolite. N2O is reduced to N2 and H2O at low temperatures in a highly efficient manner. Ammonia-mediated reduction of nitrous oxide can be effectuated from gas streams having N2O concentrations as low as 1%. The gas stream may also contact a catalytic composition selective for the reduction of NOx. In this way, N2O and Nx treatment may be effectuated in a single process stream.

Abstract: A process for adsorbing hydrocarbons from an acid gas stream includes passing the acid gas stream through an adsorbent that selectively removes hydrocarbons, desorbing the hydrocarbons from the adsorbent and contacting the desorbed hydrocarbons with an acid gas removal solution to remove acid gases which have been coadsorbed with the hydrocarbons. The process is particularly useful in removing hydrocarbons from a hydrogen sulfide-containing stream that is being directed to Claus processing for conversion into elemental sulfur. Useful adsorbents include Y-type zeolites having a silica to alumina mole ratio of less than 15 and a reduced sodium content.

Abstract: A pressure swing adsorption process for the separation of nitrogen from a mixture of same with methane, utilizing two separate PSA stages, one containing a nitrogen selective adsorbent and the second containing a methane-selective adsorbent. In the process, the first PSA unit containing a nitrogen selective adsorbent forms a product methane stream and a waste stream rich in nitrogen which is passed to a second PSA unit containing a methane selective adsorbent which forms a product nitrogen stream and a waste stream rich in methane. The waste stream rich in methane can be treated to remove heavy hydrocarbons therefrom before the methane is recycled to feed.

Abstract: A simplified method of forming a porous crystalline titanium silicate membrane comprises preforming a mass of titanium dioxide particles into a consolidated preform such as by pressing into a thin film, and contacting the thin film of titanium dioxide with an aqueous alkaline silicate synthesis solution at a temperature and for a period of time sufficient to form the titanium silicate in-situ.

Abstract: ETS-4 crystalline titanium silicate is produced so as to be enriched in at least one polymorph thereof which contains channels which interpenetrate the crystal lattice in both the b- and c-directions. A process of producing such a polymorph and enriched ETS-4 titanium silicate comprises the addition of a wetting agent to the reaction mixture.

Abstract: Improved solid products for remineralizing subsurface lesions and/or mineralizing exposed tubules in dentin contain an anionic component, a cationic component and a separating component for separating the anionic and cationic components in the product. The anionic component contains at least one water-soluble phosphate salt and the cationic component contains at least one partially water-soluble calcium salt. To remineralize subsurface lesions and/or mineralize exposed dentin tubules in a tooth, the anionic and cationic components are mixed with water and/or saliva to form a mixed aqueous composition having a pH of from greater than about 4.0 to about 10.0, which is then applied to the tooth.

Abstract: This invention relates to zeolitic molecular sieve compositions and hybrid zeolite-silica compositions characterized by novel morphology in which the zeolite is present as macroscopic aggregates of microcrystalline zeolite. The zeolitic compositions of this invention have outstanding capability to complex multivalent cations, especially calcium due to the high exchange kinetics of the microcrystalline zeolite component and yet have the ease of handling due to the macroscopic aggregate assemblage.

Abstract: A pressure swing adsorption process for the separation of nitrogen from natural gas utilizes two separate pressure swing adsorption stages, the first containing a hydrocarbon-selective adsorbent and the second containing a nitrogen-selective adsorbent. In the process, the product stream from the first pressure swing adsorption unit contains a natural gas stream having a reduced hydrocarbon content and the product stream from the second pressure swing adsorption unit is a natural gas stream having a reduced nitrogen concentration. The product from the second pressure swing adsorption unit is used to desorb the hydrocarbons from the first pressure swing adsorption unit so as to add the hydrocarbons, which have heat value to the product natural gas stream. Periodically, heating the nitrogen-selective adsorbent with heated product stream from the second pressure swing adsorption unit has been found to improve the capacity of the nitrogen-selective adsorbent to adsorb nitrogen.

Abstract: A solid oral product, e.g., chewing gum, lozenge, an edible foodstuff, and the like, which is useful for remineralizing subsurface dental lesions and/or mineralizing exposed dentinal tubules, contains (A) a discrete cationic agglomerate component composed of at least one water-soluble or partially water-soluble calcium salt and a first inert solid carrier, and (B) a discrete anionic agglomerate component composed of at least one water-soluble orthophosphate salt and a second inert solid carrier. The agglomerate nature of the cationic and anionic components keeps these components separate from one another during storage of the product but allows the cationic and anionic salts to be simultaneously released from the product upon mixing of the product with water and/or saliva to form a mixed aqueous solution such that the solution contains both calcium cations released from the calcium salt and orthophosphate anions released by the orthophosphate salt.

Abstract: Aluminosilicate zeolites are formed in a novel reaction medium which contains a silicate source and an aluminum source in an aqueous alkaline solution and which reaction medium further includes an additional electrolyte salt. The addition of the electrolyte salt provides nucleation sites for the zeolite so as to form very small crystals. In high silica reaction environments, it is possible to form high aluminum zeolites which contain occluded silicate and wherein the morphology of the zeolites comprise macroscopic aggregates of microcrystalline zeolites. The addition of the electrolyte salt can also decrease the reaction time or temperature needed for crystallization.
