  • Patent number: 11420183
    Abstract: This invention introduces a method of preparing a carbon-based sulfur-loading iron-containing adsorbent for mercury removal, which can solve the problems in the prior art that sulfur-rich heavy organic materials have low-value utilization and the elemental mercury in atmosphere is hard to be efficiently and economically removed by the existing mercury removal agents. A carbon-based sulfur-loading iron-containing adsorbent for mercury removal is prepared in this invention. The adsorbent with a porous structure is prepared in situ by performing steps such as chemical activation of sulfur-rich heavy organic materials that are rich in iron. The adsorbent prepared herein has good mercury removal performance in simulated coal-fired flue gas. This invention not only improves the utilization value of sulfur-rich heavy organic materials, but also prevents SOX pollution caused by the combustion of sulfur-rich heavy organic materials and controls mercury pollution in the coal-fired flue gas.

In select embodiments, a body comprises ash particles, and the ash particles used to form the body may be selected based on their providing one or more desired properties for a given treatment. Various bodies provide for the reaction and/or removal of a substance in a fluid, often using a porous body comprised of ash particles. Computer-operable methods for matching a source material to an application are disclosed. Certain aspects feature a porous body comprised of ash particles, the ash particles have a particle size distribution and interparticle connectivity that creates a plurality of pores having a pore size distribution and pore connectivity, and the pore size distribution and pore connectivity are such that a first fluid may substantially penetrate the pores.

  • Publication number: 20140357481
    Abstract: A device for stabilizing fuel in a fuel tank comprises activated carbon. The activated carbon is configured to be inserted into or installed inside a fuel tank, so that it is in contact with the fuel. The device allows the activated carbon to be in contact with the fuel, but does not allow it to be dispersed in the fuel. A method for stabilizing fuel in a fuel tank comprises adding the device to the fuel tank so that it is in contact with the fuel.

  • Patent number: 8845994
    Abstract: An active material of the present invention has fine pores formed in the interlayer of a carbon material capable of exhibiting electrochemical double layer capacitance. The fine pores are formed by forming an oxidized graphite structure combined with oxygen in the interlayer of a part or whole of the carbon material containing soft carbon and then removing a part or whole of oxygen in the interlayer. A method for producing an energy storage active material for use in an electrochemical double layer capacitor comprises pre-treating a carbon material through heat treatment and oxidizing the pre-treated carbon material using an oxidant. The method further comprises reducing the oxidized carbon material through heat treatment. The interlayer distances of an active material for respective steps, measured by a powder X-ray diffraction method, are 0.33˜0.36 nm in the pre-treatment step, 0.5˜2.1 nm in the oxidation step, and 0.34˜0.5 nm in the reduction step.

  • 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.
