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).

Treating a non-wine alcoholic beverage including: exposing the non-wine alcoholic beverage to an ion exchange matrix. The ion exchange matrix includes a mixture of cation exchange media and anion exchange media that includes: (1) cation exchange media that are in hydrogen form, (2) cation exchange media that are in mineral form comprising potassium mineral form, (3) anion exchange media that are in hydroxide form, and (4) anion exchange media that are in chloride mineral form. The exposing results in: binding ions of the mixture to one or more cationic or anionic constituents present in the pretreated beverage, reducing concentrations of the one or more cationic or anionic constituents in the beverage and maintaining a conductivity value of the treated beverage equal to or greater than the pretreated beverage's conductivity value. An apparatus for treating a non-wine alcoholic beverage and a treated non-wine alcoholic beverage prepared by a process are also disclosed.
