A carbon sorbent for removing carbon dioxide from a gaseous material includes a surface composition including carbon, nitrogen, and oxygen. The nitrogen atoms at the surface of the carbon sorbent may be present in pyridone, pyrrole, and pyridine. The surface of the carbon sorbent may include lactone groups and pyrone groups. The carbon sorbent may have a bulk density greater than about 0.40 grams per cubic centimeter. The carbon sorbent may be formed using amino acids to provide the nitrogen for the carbon sorbent. In addition, the use of processing aids during the formation of the carbon sorbent facilitates the formation of a denser carbon sorbent. Related methods of forming the carbon sorbent and pellets of the carbon sorbent are also disclosed.

A method for rapidly filling a compressed gas storage tank with a moderated temperature rise using a Coanda nozzle to inject the feed gas into the tank and using the Coanda nozzle to direct the feed gas along the inner surface of the storage tank; entraining the stored gas with the feed gas that is flowing under the influence of the Coanda effect to flow along the inner surface of the gas storage tank; and transferring heat from the flowing gas to the external walls of the tank. Also, a compressed gas storage tank for rapid filling with a moderated temperature rise comprising: a gas storage tank and a Coanda nozzle capable of directing feed gas that is injected into the gas storage tank along the inner surface of the gas storage tank.

The present invention provides a sorbent for the removal of carbon dioxide from gas streams, comprising: a COcapacity of at least 9 weight percent when measured at 22&#xb0; C. and 1 atmosphere; an HO capacity of at most 15 weight percent when measured at 25&#xb0; C. and 1 atmosphere; and an isosteric heat of adsorption of from 5 to 8.5 kilocalories per mole of CO. The invention also provides a carbon sorbent in a powder, a granular or a pellet form for the removal of carbon dioxide from gas streams, comprising: a carbon content of at least 90 weight percent; a nitrogen content of at least 1 weight percent; an oxygen content of at most 3 weight percent; a BET surface area from 50 to 2600 m/g; and a DFT micropore volume from 0.04 to 0.8 cc/g.

High capacity carbon dioxide sorbent

Gas desulfurization sorbents and methods using them for removal of sulfur from gas streams, particularly at high temperatures ranging from 500 to 1000&#xb0; C. The sorbents and methods are of particular application to produce a sulfur-clean feed from reformate gas generated from readily available transportation fuels containing sulfur. Sorbents of the invention can reduce the sulfur concentration in reformate gas to parts per billion on volume basis (ppbv) levels over a large range of temperatures. Sorbent materials of this invention comprise a nickel phase dispersed on a particulate support or a monolith support. The support can be a high surface area support with surface area of 100 m/g or higher. The invention also provides systems for desulfurizing reformate gas and systems for providing a desulfurized gas to a fuel cell, particularly a solid oxide fuel cell.
