  • Patent number: 9873614
    Abstract: Methods are provided for synthesis of substantially pure phase ZSM-48 crystals having a fiber or needle morphology based on synthesis mixtures containing non-sodium alkali metal ions, where the structure directing agent in the synthesis mixture can be a diquaternary alkylammonium salt with a 6-carbon atom chain between the ammonium ions (diquat-6). The methods described herein can be used to make ZSM-48 crystals having a fiber and/or needle crystal morphology from a synthesis mixture containing a diquat-6 structure directing agent. The desired morphology can be achieved in part by reducing, minimizing, and/or eliminating the presence of sodium ions in the synthesis mixture.

  • Patent number: 9662640
    Abstract: Methods for introducing mesoporosity into zeolite materials that employ an acid pretreatment step are provided. By utilizing a non-acidic chelating agent during the acid treatment step, the zeolite material can be pretreated with a strong acid, often in higher concentrations or over shorter contact times, than had previously been contemplated. The resulting acid-treated mesoporous materials retain desirable properties, including Si/Al, UCS, and total mesopore and micropore volume. The ability to use a stronger acid without damaging the zeolite material results in a less expensive process capable of producing mesoporous zeolite materials suitable for a wide range of uses.

    Abstract: Provided is a carbon dioxide adsorbent with which large quantities of carbon dioxide can be adsorbed and removed even under conditions having low carbon dioxide concentrations such as when under subatmospheric pressure or when under an environment having a carbon dioxide partial pressure of less than atmospheric pressure, said carbon dioxide adsorbent exhibiting excellent adsorption activity. A carbon dioxide adsorbent including at least a ZSM-5 zeolite including barium (Ba) or strontium (Sr) is characterized in that the ZSM-5 zeolite includes M-O-M bonds (M being Ba or Sr, and O being oxygen). The M-O-M bonds interact strongly with carbon dioxide, and thus carbon dioxide can be adsorbed effectively and in large volumes even under conditions having low carbon dioxide concentrations.
