Separation and Storage of Fluids Using ITQ-55

摘要

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)SiO2in whichM 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.

1. A method for adsorbing and storing fluids, comprising:
exposing an input fluid stream comprising a first fluid component to an adsorbent comprising zeolite ITQ-55 at a first pressure and a first temperature; maintaining the adsorbent at a second pressure and a second temperature for a storage period of time; forming an adsorbed product fluid stream comprising the first fluid component; and collecting the adsorbed product stream, wherein the zeolite ITQ-55 has a framework of tetrahedral (T) atoms connected by bridging atoms, wherein the tetrahedral atom is defined by connecting the nearest T atoms in the manner described in the following Table:ITQ-55 tetrahedral atom interconnectionsT atomConnected to:T1T6, T7, T55, T73T2T3, T5, T9, T56T3T2, T7, T21, T27T4T8, T9, T58, T73T5T2, T8, T52, T59T6T1, T8, T53, T60T7T1, T3, T50, T61T8T4, T5, T6, T51T9T2, T4, T21, T63T10T15, T16, T64, T74T11T12, T14, T18, T65T12T11, T16, T30, T36T13T17, T18, T67, T74T14T11, T17, T43, T68T15T10, T17, T44, T69T16T10, T12, T41, T70T17T13, T14, T15, T42T18T11, T13, T30, T72T19T24, T25, T37, T73T20T21, T23, T27, T38T21T3, T9, T20, T25T22T26, T27, T40, T73T23T20, T26, T41, T70T24T19, T26, T42, T71T25T19, T21, T43, T68T26T22, T23, T24, T69T27T3, T20, T22, T45T28T33, T34, T46, T74T29T30, T32, T36, T47T30T12, T18, T29, T34T31T35, T36, T49, T74T32T29, T35, T50, T61T33T28, T35, T51, T62T34T28, T30, T52, T59T35T31, T32, T33, T60T36T12, T29, T31, T54T37T19, T42, T43, T75T38T20, T39, T41, T45T39T38, T43, T57, T63T40T22, T44, T45, T75T41T16, T23, T38, T44T42T17, T24, T37, T44T43T14, T25, T37, T39T44T15, T40, T41, T42T45T27, T38, T40, T57T46T28, T51, T52, T76T47T29, T48, T50, T54T48T47, T52, T66, T72T49T31, T53, T54, T76T50T7, T32, T47, T53T51T8, T33, T46, T53T52T5, T34, T46, T48T53T6, T49, T50, T51T54T36, T47, T49, T66T55T1, T60, T61, T75T56T2, T57, T59, T63T57T39, T45, T56, T61T58T4, T62, T63, T75T59T5, T34, T56, T62T60T6, T35, T55, T62T61T7, T32, T55, T57T62T33, T58, T59, T60T63T9, T39, T56, T58T64T10, T69, T70, T76T65T11, T66, T68, T72T66T48, T54, T65, T70T67T13, T71, T72, T76T68T14, T25, T65, T71T69T15, T26, T64, T71T70T16, T23, T64, T66T71T24, T67, T68, T69T72T18, T48, T65, T67T73T1, T4, T19, T22T74T10, T13, T28, T31T75T37, T40, T55, T58T76T46, T49, T64, T67.
