Cyclic thermal swing adsorption with direct heat transfer
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.
POLYPYRROLE/GRAPHENE OXIDE NANOCOMPOSITE-COATED FIBER LOCATED IN A CAPILLARY TUBE REINFORCED BY A VACUUM SYSTEM FOR ASSESSMENT OF OXIDATIVE STABILITY OF EDIBLE OILS
A vacuum-assisted coated fiber located in a capillary tube system for sampling and delivering materials to an analytical device and a method for sampling analytes is disclosed. A sorbent comprising polypyrrole/graphene oxide is coated on a fiber inserted within an interior space of the capillary tube to entrap an analyte within a sample. The vacuum-assisted coated fiber located in a capillary tube device also includes a vacuum device configured to vacuum the extraction vial. This may improve the extraction of the analytes vapors from the sample, matrix to the sorbent bed.

SYNTHESIS OF ORDERED MICROPOROUS ACTIVATED CARBONS BY CHEMICAL VAPOR DEPOSITION
Embodiments provide a methane microporous carbon adsorbent including a thermally-treated CVD carbon having a shape in the form of a negative replica of a crystalline zeolite has a BET specific surface area, a micropore volume, a micropore to mesopore volume ratio, a stored methane value and a methane delivered value and a sequential carbon synthesis method for forming the methane microporous carbon adsorbent. Introducing an organic precursor gas for a chemical vapor deposition (CVD) period to a crystalline zeolite that is maintained at a CVD temperature forms the carbon-zeolite composite. Introducing a non-reactive gas for a thermal treatment period to the carbon-zeolite composite maintained at a thermal treatment temperature forms the thermally-treated carbon-zeolite composite. Introducing an aqueous strong mineral acid mixture to the thermally-treated carbon-zeolite composite forms the methane microporous carbon adsorbent.
