  • Patent number: 10464817
    Abstract: EMM-26 is a novel synthetic crystalline material having a single crystalline phase with a unique T-atom connectivity and X-ray diffraction pattern which identify it as a novel material. EMM-26 has a two-dimensional pore system defined by 10-membered rings of tetrahedrally coordinated atoms having pore dimensions of ˜6.3 ?ט3.2 ?. EMM-26 may be prepared with a organic structure directing agent, such as 1,6-bis(N-methylpyrrolidinium) hexane dications and/or 1,6-bis(N-methylpiperidinium) hexane dications. EMM-26 may be used in organic compound conversion and/or sorptive processes.

  • Patent number: 9168483
    Abstract: Methods are provided for forming zeolite crystals suitable for gas phase separations with transport characteristics that are stable over time. The zeolitic materials and/or corresponding methods of synthesis or treatment described herein provide for improved stability in the early stages of process operation for some types of gas phase separations. The methods allow for synthesis of DDR type zeolites that have reduced contents of alkali metal impurities. The synthetic methods for reducing the non-framework alkali metal atom or cation impurity content appear to have little or no impact on the DDR crystal structure and morphology.

  • Patent number: 8192709
    Abstract: The present invention relates to the selective separation of methane (“CH4”) from higher carbon number hydrocarbons (“HHC”s) in streams containing both methane and higher carbon number hydrocarbons (e.g. ethylene, ethane, propylene, propane, etc.) utilizing a zeolitic imidazolate framework (“ZIF”) material. Preferably, the stream to be separated is fed to the present process in a substantially gaseous phase. In preferred embodiments, the current invention is utilized in a process to separate methane from higher carbon number hydrocarbons in natural gas streams.

  • Patent number: 7683233
    Abstract: In a process for producing a para-xylene enriched product from a gaseous mixture comprising at least para-xylene, meta-xylene and ortho-xylene, the gaseous mixture is contacted with an adsorbent capable of selectively adsorbing para-xylene and comprising a crystalline molecular sieve having an average crystal size between about 0.5 micron and about 20 microns. The contacting is conducted at a temperature and pressure such that at least part of the para-xylene in the mixture is adsorbed by the adsorbent to produce a para-xylene-depleted effluent stream. The para-xylene is then desorbed from said adsorbent and collected to form a para-xylene enriched stream. The adsorption and desorption steps are repeated for a plurality of cycles, such that the time between successive contacting steps is no more than 10 seconds.
