    摘要： Embodiments of crystalline, titanium silicate molecular sieves are described having a formula representing mole ratios of oxides of nM1O:TiO2:ySiO2:zH2O:wX where M1 refers to a metal cation or mixture of metal cations; n is from about 1 to about 2; y is from about 1 to about 10; z is from 0 to about 100; X is a halide anion other than fluorine, or combination of halide anions that excludes fluorine; and w is greater than 0. The pore size of the sieves can be adjusted by ion exchanging M1 cations with a suitable amount of another species. Embodiments of the invention are useful for various adsorptive fluid separation processes, including pressure swing adsorption processes. For example, disclosed embodiments are useful for separating methane from air.

    摘要： A hydrogen sulphide adsorbent is formed from an alkali metal nanotitanate having a portion of the alkali metal cations exchanged with metal cations reactive with hydrogen sulphide, and heat treated. A method for producing the adsorbent includes the steps of mixing an alkali metal nanotitanate in powder form into an aqueous metal cation solution to produce a slurry, which is subsequently dehydrated to produce a powder, which is heat treated. A low temperature method for removing hydrogen sulphide from a gaseous mixture involves exposing the gaseous mixture to the aforementioned adsorbent, at a temperature less than 250° C. The adsorbent maintains a high adsorption capacity over a range of activation temperatures and humidity conditions.
