Abstract: The present invention is directed to a method of preparing a synthetic crystalline material, designated as JMZ-12, with a framework built up by the disorder AEI and CHA structures, substantially free of framework phosphorous and prepared preferably in the absence of halides such as fluoride ions. Such method comprises the step of heating a reaction mixture under crystallization conditions for a sufficient period to form a disordered zeolite having both CHA and AEI topologies, wherein the reaction mixture comprises at least one source of aluminum, at least one source of silicon, a source of alkaline or alkaline-earth cations, and a structure directing agent containing at least one source of quaternary ammonium cations and at least one source of alkyl-substituted piperidinium cations in a molar ratio of 0.20 to about 1.4. The resulting zeolites are useful as catalysts, particularly when used in combination with exchanged transition metal(s) and, optionally, rare earth metal(s).

Abstract: Waste saline waters are purified by contacting with a cation exchange resin in hydrogen form, then with a WBA resin and, if desired, with a SBA resin. The cation exchange resin is regenerated with a strong acid reagent. The WBA resin is regenerated with ammonium hydroxide reagent. The SBA resin is regenerated with an alkali metal hydroxide. The residual reagent values in the spent regenerants are applied to the soil as amendments, fertilizer, for pH control, wind erosion control, deicing roadways and in Enhanced Oil Recovery.

Abstract: A process for fluoride removal from wastewater streams produced during industrial operation for further industrial use or to comply with environmental regulations. The process segregates the removal of fluoride and fluorosilicate ions, from the totality of ions in the waste water stream, thus improving treatment efficiency and reducing costs. Ion-exchange chromatography is used to remove the fluoride and fluorosilicate ions by passing the wastewater stream through one or more columns that contain a charged resin which selectively binds cations/anions in the stream. The fluoride ions are washed from the column and then collected for removal or use in other processes.

Abstract: The present invention provides a multiple bed-type condensate demineralization method and apparatus for the method that are able to provide an improved treated water quality in ammonia operation by substantially reducing the cross contamination ratio during resin regeneration from the current cross contamination ratio.In the method of condensate demineralization using ion-exchange resin in a multiple-bed regime, condensate is passed through a resin layer having a multiple-bed structure in which an anion resin layer and a layer of a uniform particle size strong acid gel-type cation resin with a 10% to 16% degree of crosslinking, divided by a partition in such a manner that they do not mix with each other, are combined in alternation. The uniform particle size strong acid gel-type cation resin with a 10% to 16% degree of crosslinking is an ion-exchange resin that has a uniform particle size of 500 to 800 μm for which at least 95% of the resin particles fall in the range defined by the average particle size ±100 μm and the uniformity coefficient is less than or equal to 1.2. Ion-exchange resin that has come to require chemical regeneration is separately withdrawn and subjected to chemical regeneration by type and is returned into the originating partition.
