摘要:
A new class of carbon-based sorbents for vapor-phase mercury removal is disclosed in this invention. The optimum structure of the sorbent particles, and a method to produce the sorbent, are described. The sorbent is based on carbon particles with a metal-oxide coating on the surface. The thin metal-oxide layer acts as a barrier for the adsorption of Air Entrainment Admixture (AEA), the component used to stabilize bubbles in cement), thereby enhancing its concrete friendliness. The metal-oxide is coated on the surface of carbon, using a solution-based method. The metal-oxide coated carbon was further modified with sulfur molecules, to increase its mercury removal capacity.
摘要:
Surface functionalized sorbent particles for vapor-phase mercury removal, especially in the presence of SO3 in, for example, flue gas. The sorbent surface is modified to increase the SO3 resistance of vapor-phase mercury sorbents. The mercury removal efficiency is immune to the presence of SO3, which is not the case with conventional activated carbon as well as brominated activated carbons. The sorbent is based on carbon particles with a metal oxide coating on the surface. The thin metal oxide layer acts as an amenable surface to introduce functional groups. The metal oxide coated carbon was further modified with amine molecules, to increase its resistance towards SO3 poisoning.
摘要:
A new class of sorbents for the removal of mercury from contaminated water. The optimum structure of the sorbent particles and a method to produce the same is described. The newly developed carbon-based particles are differentiated from other sorbent particles by their high accessible surface area and high affinity towards mercury ions that leads to faster and higher mercury adsorption. The sorbent is based on carbon particles with a metal-oxide coating on the surface. The metal-oxide is coated on the surface of carbon, using a solution-based method. The metal-oxide coated carbon was further modified with sulfur molecules, to increase its mercury removal capacity.
摘要:
A method for producing nanostructured multi-component or doped oxide particles and the particles produced therein. The process includes the steps of (i) dissolving salts of cations, which are either dopants or components of the final oxide, in an organic solvent; (ii) adding a dispersion of nanoparticles of a single component oxide to the liquid solution; (iii) heating the liquid solution to facilitate diffusion of cations into the nanoparticles; (iv) separating the solids from the liquid solution; and (v) heat treating the solids either to form the desired crystal structure in case of multi-component oxide or to render the homogeneous distribution of dopant cation in the host oxide structure. The process produces nanocrystalline multi-component or doped oxide nanoparticles with a particle size of 5–500 nm, more preferably 20–100 nm; the collection of particles have an average secondary (or aggregate) particle size is in the range of 25–2000 nm, preferably of less than 500 nm.
摘要:
An image estimation apparatus includes: a forming unit that forms a reference frame with a size determined uniquely in accordance with a size of a recording region where an image is recorded; and an estimating unit that estimates a type of a single image based on a size of a bounding frame around the single image and the size of the reference frame formed by the forming unit, the single image being a target of type inference in an image contained in a designation region in a recording region image which is an image indicating the recording region where an image is recorded.
摘要:
Computer hardware logic displays a computer-generated geographic map on a video display through the use of a receiving logic and a zooming logic. The receiving ic detects an input signal for initiating a map zoning mode for an initial computer-generated geographic map. This map zoning mode prevents zooming of the entire initial computer-generated geographic map. The zooming logic zooms a user-selected area on the initial computer-generated geographic map, thus generating a zoom window that displays and overlays an enlarged view of the user-selected area over the initial computer-generated geographic map.

摘要:
An image processing apparatus includes an estimating unit and a hiding unit. The estimating unit extracts a subject specifying mark image corresponding to a specifying mark from a recording area image corresponding to a recording area in which an image is recorded, plural predetermined types of specifying marks having predetermined attributes different from an attribute of the image of the recording area and being used for specifying a region within the recording area by using different specifying methods, at least one of the plural predetermined types of specifying marks being recorded in the recording area. The estimating unit estimates the type of specifying mark corresponding to the extracted subject specifying mark image. The hiding unit hides the region specified by the type of specifying mark estimated by the estimating unit by using a hiding method which is uniquely determined for the estimated type of specifying mark.
