  • Patent number: 10662126
    Abstract: Methods of simultaneously converting butanes and methanol to olefins over Ti-containing zeolite catalysts are described. The exothermicity of the alcohols to olefins reaction is matched by endothermicity of dehydrogenation reaction of butane(s) to light olefins resulting in a thermo-neutral process. The Ti-containing zeolites provide excellent selectivity to light olefins as well as exceptionally high hydrothermal stability. The coupled reaction may advantageously be conducted in a staged reactor with methanol/DME conversion zones alternating with zones for butane(s) dehydrogenation. The resulting light olefins can then be reacted with iso-butane to produce high-octane alkylate. The net result is a highly efficient and low cost method for converting methanol and butanes to alkylate.

  • Publication number: 20140283545
    Abstract: There is provided a water vapor adsorbent for adsorption heat pumps that has high adsorption and desorption performance and high water resistance, such as submersion resistance. The water vapor adsorbent contains a zeolite that contains at least a silicon atom, an aluminum atom, and a phosphorus atom in its framework structure and that has a framework density of 12.0 T/1,000 cubic angstroms or more and 16.0 T/1,000 cubic angstroms or less, wherein the water vapor adsorbent contains a group 11 metal of the periodic table, which constitutes 0.1% to 15% by weight of the zeolite. In the zeolite containing the group 11 metal, an ion of the group 11 metal substitutes for a Bronsted acid site, which promotes a hydrolysis reaction of the zeolite, and decreases the number of Bronsted acid sites of the zeolite, thereby improving the water resistance, such as submersion resistance, of the zeolite.

  • Patent number: 8658127
    Abstract: A method of preparing a mesoporous zeolite material is disclosed. The method comprises forming template-occluded primary metal-doped silicate particles having an amorphous structure and aggregating the particles into mesoporous agglomerates. The amorphous structure is further transformed into a microporous nanocrystalline zeolite structure, thereby forming a mesoporous zeolitic material. Forming the mesoporous zeolite material includes removing the template from the template-occluded particles.
