Abstract: This invention refers to a microporous crystalline material of zeolitic nature that has, in its calcined state and in the absence of defects in its crystalline matrix manifested by the presence of silanols, the empirical formula x(M1/nXO2):yYO2:gGeO2:(1−g)SiO2 in which M is selected between H+, at least one inorganic cation of charge +n, and a mixture of both, X is at least one chemical element of oxidation state +3, Y is at least one chemical element with oxidation state +4 different from Si, x takes a value between 0 and 0.2, both included, y takes a value between 0 and 0.1, both included, g takes a value between 0 and 0.5, both included that has been denoted ITQ-55, as well as a method for its preparation. This invention also relates to uses of the crystalline material of zeolitic nature for adsorption of fluid components, membrane separation of fluid components, storage of fluid components, and catalysis of various conversion reactions.

Abstract: Systems and methods are provided for separating oxygen from air using a sorption/desorption cycle that includes a reduced or minimized difference between the maximum and minimum pressures involved in the sorption/desorption cycle. The reduced or minimized difference in pressures can be achieved in part by using valves that can allow for commercial scale flow rates while avoiding large pressure drops for flows passing through the valves. A rotary wheel adsorbent is an example of a system that can allow for a sorption/desorption cycle with reduced and/or minimized pressure drops across valves associated with the process. Stationary adsorbent beds can also be used in combination with commercially available valves that have reduced and/or minimized pressure drops.

Abstract: In a process for separating one or more 3,3′-, 3,4′- and 4,4′-dimethyl biphenyl isomers, a feed comprising the isomers is contacted with an adsorbent containing a zeolite having a largest diffuse along dimension of at least 4 Angstroms. The adsorbents provide selective adsorption of 4,4′-dimethyl biphenyl.
