Abstract: A system and method for recovering high value gas from a process stream, material or environment containing same, e.g., xenon by contacting gas from the process stream, material or environment with a carbon adsorbent effective to sorptively capture same, free of or with reduced concentration of fluid species present with the high value gas in the high value gas-containing gas in the process stream, material or environment. Other aspects of the disclosure include a radon detection method and product.

Abstract: A particulate form carbon pyrolyzate adsorbent, having the following characteristics: (a) CO2 capacity greater than 105 cc/gram at one bar pressure and temperature of 273° Kelvin; (b) CO2 Working Capacity greater than 7.0 weight percent; (c) CO2 heats of adsorption and desorption each of which is in a range of from 10 to 50 kJ/mole; and (d) a CO2/N2 Henry's Law Separation Factor greater than 5. The carbon pyrolyzate material can be formed from a polyvinylidene chloride-based polymer or copolymer, or other suitable resin material, to provide an adsorbent that is useful for carbon dioxide capture applications, e.g., in treatment of flue gases from coal-fired power generation plants.

Abstract: A system and process for generating and packaging phosphine gas, in which the process includes: reacting water and aluminum phosphide to generate phosphine, and providing the phosphine in a gas mixture at a phosphine concentration below a lower explosive limit; adsorptively removing phosphine from the gas mixture; and packaging the removed phosphine in a fluid storage and dispensing vessel.

Abstract: A carbon adsorbent having the characteristics of: a nitrogen micropore volume at 77° K, measured as liquid capacity, that is greater than 0.30 mL/g; a neopentane capacity measured at 273° K and 1 bar, measured as liquid capacity, that is less than 7% of the nitrogen micropore volume, measured as liquid capacity; and an access pore size in a range of from 0.50 to 0.62 nm. Such adsorbent is usefully employed for contacting with hydrocarbon mixtures to adsorb low-octane, linear and mono- or di-substituted alkanes therefrom, and thereby increase octane rating, e.g., of an isomerization naphtha raffinate. Adsorption processes and apparatus are also described, in which the carbon adsorbent can be utilized for production of higher octane rating hydrocarbon mixtures.
