Silicate materials, method for their manufacture, and method for using such silicate materials for adsorptive fluid separations

摘要: Embodiments of crystalline, titanium silicate molecular sieves are described having a formula representing mole ratios oxides n M1O:TiO2:y SiO2:zH2O:wX where Mi refers to metal cation or mixture cations; is from about 1 2; y 10; z 0 100; X halide anion other than fluorine, combination anions that excludes fluorine; and w greater 0. The pore size the can be adjusted by ion exchanging cations with suitable amount another species. invention useful for various adsorptive fluid separation processes, including pressure swing adsorption processes. For example, disclosed embodiments separating methane air.
