The invention concerns a method for the storage and/or aging of meat in which raw meat is stored in the presence of an alkaline and/or alkaline earth metal carbonate, which is made available in a matrix (1) of aligned and/or non-aligned fibers (2), and an element for use in the storage and/or aging of meat, which comprises a layer of ordered and/or unordered fibers and optionally further layers, which element contains alkaline and/or alkaline earth metal carbonates and/or hydrogen carbonates. By means of the claimed method, aging of raw meat can be carried out in a simple manner without having to give up the taste quality achieved by dry aging.

The present disclosure relates to an apparatus, system and method for selectively capturing a carbon-containing gas from an input gas mixture.

Embodiments of an apparatus including a front-end pre-concentrator module including an inlet, an outlet, and at least one valve to control flow through the inlet, the outlet, or both. The apparatus includes a back-end pre-concentrator module including an inlet, an outlet, and at least one valve to control flow through the inlet, the outlet, or both, and also includes a gas analysis module having an inlet and an outlet and including a gas chromatograph having an inlet and an outlet. The outlet of the front-end pre-concentrator and the outlet of the back-end pre-concentrator are coupled to the inlet of the gas analysis module. Other embodiments are also disclosed and claimed.

The present disclosure provides a method for generating higher hydrocarbon(s) from a stream comprising compounds with two or more carbon atoms (C.sub.2+), comprising introducing methane and an oxidant (e.g., O.sub.2) into an oxidative coupling of methane (OCM) reactor. The OCM reactor reacts the methane with the oxidant to generate a first product stream comprising the C.sub.2+ compounds. The first product stream can then be directed to a separations unit that recovers at least a portion of the C.sub.2+ compounds from the first product stream to yield a second product stream comprising the at least the portion of the C.sub.2+ compounds.

A vapor separator in an embodiment is arranged between a first space and a second space, and is used to allow vapor existing in the first space to permeate the second space by making a vapor pressure in the second space lower than a vapor pressure in the first space. The vapor separator in the embodiment includes: a porous body having a first face, a second face opposite to the first face, and fine pores passing from the first face to the second face; and a soluble absorbent existing in the fine pores of the porous body.

One embodiment of the the invention is a method to develop a chemical battery for captured carbon dioxide, comprising: utilizing a hydroxide compound in water to absorb carbon dioxide from industrial exhaust gas; resulting in a solution of carbonates and bicarbonates in water; dewatering the solution, leaving solid carbonates and bicarbonates and thermally decomposing the solid carbonates and bicarbonates to an oxide compound, releasing pure CO2 gas; hydrating the oxide compound with water, forming a hydroxide compound; and then repeating the top step indefinitely. The hydroxide compound could be any one of sodium hydroxide, potassium hydroxide, magnesium hydroxide, or lithium hydroxide; and the respective oxide compound could be any one of sodium oxide, potassium oxide, magnesium oxide, or lithium oxide.

In some embodiments, a solid oxide fuel system is provided. The solid oxide fuel cell system may include a chromium-getter material. The chromium-getter material may react with chromium to remove chromium species from chromium vapor. The solid oxide fuel cell system may also include an inert substrate. The chromium-getter material may be coated onto the inert substrate. The coated substrate may remove chromium species from chromium vapor before the chromium species can react with a cathode in the solid oxide fuel cell system.

A system and method for treating, degrading, and incinerating a fluorocarbon or fluorinated material, such as Freon, with reduced emissions of gaseous perfluorinated compounds (PFCs) is provided. The method includes mixing the fluorinated material with a hydroxide base and optionally a solvent, such as polyethylene glycol ether, N-methylpyrrolidone, cyrene, and/or deionized water in a batch reactor to form a reaction mixture, also referred to as a suspension. The reaction mixture is heated to a temperature ranging from about 25 C. to about 400 C. for about 0.5 hours to about 240 hours to defluorinate the fluorinated material and produce a defluorinated waste product. More specifically, the method converts organic fluorine present in the fluorinated material, such as Freon, to inorganic fluoride. Thus, the defluorinated waste product can be incinerated with reduced emissions of harmful gaseous PFCs.

The present disclosure relates to the extraction of lithium from liquid resources such as natural and synthetic brines, leachate solutions from clays and minerals, and recycled products.

A composition for use in brine formation having a deliquescent desiccant, urea, and an optional component selected from the group consisting of starch, citric acid, clay, glucose, and a combination thereof. Methods of making and using the composition are provided. The composition may be pressed into tablet form. The composition may be used in a dehumidifying device.
