  • Patent number: 9963349
    Abstract: Methods for introducing mesoporosity into zeolitic materials are described herein that employ an acid treatment, an optional surfactant treatment, and a base treatment without filtration or purification steps between the steps. In particular, the process generally involves subjecting a zeolitic material to an acid treatment followed by a surfactant treatment and base treatment. The methods can efficiently introduce mesoporosity into various zeolitic materials, such as zeolites.

  • 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.

  • Patent number: 7807132
    Abstract: A quantity of solution sufficient to dissolve a pH controlling substance and/or substantially dissolve a surfactant without substantial excess solution is controlled under a set of time and temperature conditions to transform an inorganic material having long-range crystallinity to a mesostructure having long-range crystallinity. The method employs concentrated conditions that have a consistency similar to a thick slurry. The economic viability of scaling up such thick slurry methods is improved relative to prior more dilute methods of transforming an inorganic material to a mesostructure.
