  • Patent number: 10807875
    Abstract: The zeolite UTD-1 may be formed under hydrothermal synthesis conditions using a directing agent that does not include a metal atom therein. Methods for synthesizing the zeolite UTD-1 may comprise: combining at least a silicon atom source and a directing agent having a structure of in an aqueous medium; forming the zeolite in the aqueous medium under hydrothermal synthesis conditions, such that the zeolite has a framework silicate with a cationic portion of the directing agent occluded within pores or channels of the framework silicate; and isolating the zeolite from the aqueous medium. The zeolite has a powder x-ray diffraction pattern with at least the following 2?scattering angles: 6.0±0.12, 7.6±0.1, 14.66±0.15, 19.7±0.15, 21.27±0.15, 22.13±0.15, 22.61±0.15, and 24.42±0.10 for a borosilicate form zeolite, or 6.0±0.12, 7.6±0.15, 14.55±0.15, 19.64±0.15, 21.01±0.20, 21.90±0.20, 22.34±0.20, and 24.38±0.20 for an aluminosilicate form zeolite.

  • Patent number: 9968882
    Abstract: A heat transfer fluid can be used as part of a multi-phase adsorption environment to allow for improved separations of gas components using a solid adsorbent. The heat transfer fluid can reduce or minimize the temperature increase of the solid adsorbent that occurs during an adsorption cycle. Reducing or minimizing such a temperature increase can enhance the working capacity for an adsorbent and/or enable the use of adsorbents that are not practical for commercial scale adsorption using conventional adsorption methods. The multi-phase adsorption environment can correspond to a trickle bed environment, a slurry environment, or another convenient environment where at least a partial liquid phase of a heat transfer fluid is present during gas adsorption by a solid adsorbent.
