Advanced adsorptive separation processes for molecular class separation
A method for separating classes of hydrocarbon compounds from a feed stream including a hydrocarbon mixture is disclosed. The method includes the steps of passing a feed stream through a plurality of separation units arranged in a series in any order, wherein each separation unit has an adsorbent material; and separating classes of hydrocarbon compounds from the feed stream. When one of the plurality of separation units comprises an adsorbent material that is a metal organic framework selected from a zirconium, hafnium, cerium, or titanium-based metal organic framework, then another plurality of separation units includes an adsorption material that is different from the metal organic framework. The method is conducted in a liquid phase. The method can also use a single separation unit with a continuous cyclic bed apparatus. The method can be combined with refining and downstream processes.
METHOD FOR ENHANCING VOLUMETRIC CAPACITY IN GAS STORAGE AND RELEASE SYSTEMS
The present disclosure provides for a porous gas sorbent monolith with superior gravimetric working capacity and volumetric capacity, a gas storage system including a porous gas sorbent monolith of the present disclosure, methods of making the same, and method for storing a gas. The porous gas sorbent monolith includes a gas adsorbing material and a non-aqueous binder.
MODIFIED ZEOLITE FOR HEAVY METAL REMOVAL
The present invention relates to the use of particulate mineral material comprising modified heulandite group zeolite for removing heavy metal cations from a liquid medium, wherein at least a part of the exchangeable cations in the heulandite group zeolite is replaced by ammonium cations.
SINTERED POROUS ELASTOMERIC MATERIAL AND APPLICATION OF THE SAME
A sintered elastomeric material combined with at least one absorbent material and formed into a thin compressible sheet. The material finds particular use in venting or filtering gasses. In specific examples, the elastomeric material may be a thermoplastic elastomer and the absorbent material may be carbon. When an amount of carbon (or any other type of conductive material) included with the elastomeric material is high enough, the material may also find use as a conductive material.

Aged spirit preservation systems and devices
Many embodiments described herein prevent an aged spirit from degrading due to the oxygen trapped in the headspace without the use of a pump. The aged spirit preservation system may have a cork with an open top, an open bottom, and a channel extending from the open top to the open bottom. The cork may be sized couple to an internal portion of a bottle. The system may even include a sealing device coupled to an outer portion of the cork between the open top and the open bottom. Additionally, the system may include a replaceable cartridge containing an adsorbent media, iron, a salt, and a color-changing indicator. Oxygen from the bottle may be allowed to enter the cartridge and react with the iron via a non-reversible reaction, thereby preventing the degradation of the spirit.

Gas dehydration with mixed adsorbent/desiccant beds
Mixed adsorbent/desiccant beds comprising in some embodiments from about 20 vol % (volume percent) to about 90 vol % of one or more adsorbents and from about 10 vol % to about 80 vol % of one or more desiccants, based on the total volume of the adsorbent/desiccant mixture, prevent water reflux during thermal regeneration of adsorption beds in gas processing plants and methods.

Catalyst compositions and their use in aromatic alkylation processes
Catalyst composition which comprises a first zeolite having a BEA* framework type and a second zeolite having a MOR framework type and a mesopore surface area of greater than 30 m.sup.2/g is disclosed. These catalyst compositions are used to remove catalyst poisons from untreated feed streams having one or more impurities which cause deactivation of the downstream catalysts employed in hydrocarbon conversion processes, such as those that produce mono-alkylated aromatic compounds.
