摘要:
본 출원은 게터재, 이를 포함하는 흡습성 필름 및 유기 전자 소자에 관한 것이다. 구체적으로 본 출원에 따른 게터재를 포함하는 흡습성 필름은 유기 전자 소자의 전면 및/또는 후면에 위치하여, 수분을 효율적으로 흡수 차단함으로써 유기 전자 소자의 수명과 내구성을 향상시킬 수 있다. 또한, 본 출원의 게터재는 나노 크기의 흡습성 입자를 사용함으로써, 흡습성 필름의 투명성을 확보하여 상부 발광형 소자(top emitting device)를 구현함과 동시에, 제조 공정 중에 흡습성 입자가 대기 중의 수분을 급격히 흡수하여 흡습 총량이 손실되는 문제를 해결할 수 있다.
摘要:
A method for modifying the properties of a sorbent comprising washing a sorbent with a washing solution so as to achieve an exchange of ions between the sorbent and the washing solution, and applying a halogen compound to the sorbent that has been washed with the washing solution to achieve a predetermined concentration of the halogen on the sorbent.

摘要:
A method for desulfurizing natural gas includes contacting the natural gas with an adsorbent which preferentially adsorbs at least one of hydrogen sulfide, COS, sulfur odorants, or combinations thereof, at a selected temperature and pressure, thereby producing desulfurized natural gas and an at least one of hydrogen sulfide/COS/sulfur odorant/combinations thereof-rich adsorbed component. The adsorbent includes a copper species adapted to form π-complexation bonds and direct metal-sulfur bonds with the at least one of hydrogen sulfide, COS, sulfur odorants, or combinations thereof, and wherein the preferential adsorption occurs by π-complexation and direct metal-sulfur bonding.

摘要:
Sorbents for removal of mercury and other pollutants from gas streams, such as a flue gas stream from coal-fired utility plants, and methods for their manufacture and use are disclosed. The methods include mixing sorbent substrate particles with a sulfide salt and a metal salt to form a metal sulfide on the outer surface of the sorbent particles.
摘要:
Rare earth metal compounds, particularly lanthanum, cerium, and yttrium, are formed as porous particles and are effective in binding metals, metal ions, and phosphate. A method of making the particles and a method of using the particles is disclosed. The particles may be used in the gastrointestinal tract or the bloodstream to remove phosphate or to treat hyperphosphatemia in mammals. The particles may also be used to remove metals from fluids such as water.
摘要:
The present invention is an improved filtration system, filtering method and unique chemical composition for capturing mercury and other pollutants in flue gases generated by process gas streams. The improved filtration system may take various forms depending on the type of filter system most desired for a particular application; however, the filter system includes at least a filter element or elements and an adsorbent component having a composition suitable for capturing mercury on the downstream side of the filter element.
摘要:
A method for the removal of mercury and other metals, as well as furans and other organic compounds from high temperature and moisture gaseous streams. The method utilizes and adsorption powder characterized as containing a carbon-based powder and an effective amount of cupric chloride suitable to remove metals and organic compounds. The powder may contain calcium hydroxide, sulphur, potassium permanganate, potassium iodide, and combinations thereof. The Figure illustrates the method of the present invention wherein a solid phase (2) is pre-screened and transferred to a cleaning unit (4). A gaseous component is transferred to a dust remover (6), while a solid components transferred to cooling unit (8). The gaseous component is then heated in cleaning unit (10); transferred to a cooling chamber(12); contacted with an adsorption powder; transferred to a baghouse (16); filtered; and exhausted as flue gases at stack (18).
