Estimating the term…
An adsorbent having porosity expanded by contact with a first agent effecting such expansion and a pressurized second agent effecting transport of the first agent into the porosity, wherein the adsorbent subsequent to removal of the first and second agents retains expanded porosity. The adsorbent can be made by an associated method in which materials such as water, ethers, alcohols, organic solvent media, or inorganic solvent media can be utilized as the first agent for swelling of the porosity, and helium, argon, krypton, xenon, neon, or other inert gases can be employed as the pressurized second agent for transport of both agents into the porosity of the adsorbent, subsequent to which the agents can be removed to yield an adsorbent of increased capacity for sorbable fluids, e.g., organometallic compounds, hydrides, halides and acid gases. Also described is a nanoporous carbon composite having porosity that is at least partially filled with material imparting to the composite an enhanced character with respect to characteristics selected from the group consisting of hardness, wear-resistance and toughness, as compared with the nanoporous carbon alone.
A gas supply package, comprising a vessel, a valve head assembly coupled to the vessel, and a carbon adsorbent in an interior volume of the vessel, wherein the gas supply package is characterized by at least one of the features of:
A composite material comprising porous carbon including porosity impregnated with tungsten carbide.
An infrared emitter device comprising carbon adsorbent, having silane adsorbed thereon, in a container adapted to allow selective ingress of oxygen from an ambient environment of the container for generation of an infrared radiation signature by reaction of said oxygen and silane, with said container being adapted to emit said infrared radiation signature externally of the container.
A desulfurization process for removing aromatic sulfur-containing compounds from a hydrocarbon material containing such compounds, said process comprising contacting said hydrocarbon material with a nanoporous carbon adapted to remove said compounds from said hydrocarbon material to a level less than 1 ppm by weight.
