  • Publication number: 20140274659
    Abstract: Adsorbed natural gas (ANG) technology is an energy efficient approach for storing NG at room temperature and low pressure. ANG technology can be applied to several aspects of the NG industry. The usage of an adsorbent material in natural gas storage and transport may provide increased storage density of NG at a given pressure and decreased pressure of gaseous fuel at a given gas density. Such adsorbent materials have been shown to store substantial quantities of natural gas at relatively modest pressures. Because lower-pressure vessels can be far less expensive than comparable sized high-pressure vessels, ANG based storage can be used to lower the cost of storing natural gas in various applications.

  • Patent number: 8309052
    Abstract: Methods for producing devolatilized and/or activated carbon in a reactor or reaction vessel of a heat treatment system from a suitable carbonaceous feedstock by introducing the feedstock into the reactor tangentially at a rotational velocity of at least 90 RPM. The methods include the steps of providing a combination of conveying means and a gas flow having various compositions and creating distinct carbonaceous feedstock material flow patterns and process conditions such that the feedstock is conveyed through the reactor or reaction vessel and heated via combustion, thereby producing activated carbon or other heat-treated carbons while concurrently avoiding adverse reaction conditions. Single and two-stage heat treatment systems may be used to heat a carbon feedstock, to which one or more industrial minerals may be added to co-produce compositions such as lime with the heat-treated carbon.

  • Patent number: 8282787
    Abstract: A system and process for gasification of a carbonaceous feedstock uses pyrolysis to produce a gas product, which may include methane, ethane, and other desirable hydrocarbon gases, and a solids product, which includes activated carbon or carbon. The gas product may then be filtered using at least a portion of the activated carbon from the solids product as a filtering medium. In an embodiment, at least some of the noxious chemicals are sequestered or removed from the gas product in one or more filtering steps using the activated carbon as a filtering medium. In a further embodiment, the filtering steps are performed in stages using activated carbon at different temperatures. A high-temperature pyrolysis system that produces activated carbon may be combined with another high-temperature pyrolysis system that does not produce activated carbon to provide filtering of noxious compounds using activated carbon from the first high-temperature pyrolysis system.
