  • 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.

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.
