Abstract:
An adsorbent for carbon dioxide may include a structure that includes composite metal oxide including a first metal (M1) and a second metal (M2) linked through oxygen (0). The first metal (M1) may be selected from an alkali metal, an alkaline-earth metal, and a combination thereof. The second metal (M2) may have a trivalent oxidation number or greater. The composite metal oxide may include mesopores inside or in the surface thereof. The adsorbent may be included in a capture module for carbon dioxide. A method of reducing emissions may include adsorbing carbon dioxide using the adsorbent for carbon dioxide.
Abstract:
An adsorbent for carbon dioxide may include a composite metal oxide including a divalent first metal (M1), a trivalent second metal (M2), and an element (A) with an electronegativity of about 2.0 to about 4.0. The composite metal oxide may have an amorphous structure. A method of manufacturing the adsorbent for carbon dioxide and a capture module for carbon dioxide including the adsorbent for carbon dioxide are also disclosed.
Abstract:
A filter and a filter system including the filter. The filter includes a porous filter frame having a first upstream-side surface, and a second downstream-side surface based on a thickness direction, the porous filter frame filtering particulate matter. A copper material layer is disposed on at least a portion of the first upstream-side surface of the filter frame.
Abstract:
A carbon dioxide adsorbent may include a double salt having a first metal salt and a second metal salt. The first metal salt may include a first metal selected from Ca, Sr, and Ba. The second metal salt may include a second metal selected from Li, Na, K, Rb, and Cs. The present disclosure also discloses a process for preparing the carbon dioxide adsorbent and a method of separating carbon dioxide using the same.
Abstract:
A carbon dioxide adsorbent may include a chabazite zeolite containing an alkali metal ion or alkaline earth metal ion. The chabazite zeolite may have a Si/Al mole ratio of about 1 to about 9.9 and mesopores. The carbon dioxide adsorbent may be included in a carbon dioxide capture module. The carbon dioxide adsorbent may also be used in a method of separating carbon dioxide.
Abstract:
An adsorbent for carbon dioxide may include an inorganic oxide porous structure having a plurality of mesopores and an active compound bound to the surface of the mesopores. The active compound may be selected from an alkali metal-containing compound, an alkaline-earth metal-containing compound, and a combination thereof. Various example embodiments also relate to a method of preparing the adsorbent for carbon dioxide and a capture module for carbon dioxide including the adsorbent for carbon dioxide.
Abstract:
An air purifier includes a reactor having a hollow shape extending in a first direction, a first purifying portion disposed inside the reactor in a fixed manner, where the first purifying portion has a facing surface perpendicular to the first direction, and includes an adsorbent for adsorbing a pollutant inflowing into the reactor and a first catalytic oxidant for removing a desorbed pollutant, and a heating portion disposed opposite to the facing surface, where the heating portion applies heat to a partial area of the first purifying portion, and is movable with respect to the first purifying portion along a plane perpendicular to the first direction.
Abstract:
An outdoor air cleaning system includes a partition surrounding a purification space to isolate the purification space from an external space and having at least one opening connecting the purification space to the external space, an air purifying device configured to supply purified air to the purification space, and a controller configured to control the air purifying device. An openness level defined as an area ratio of the opening with respect to a surface area of the partition is about 10% or more and about 50% or less.
