Mechanisms of Mercury Capture and Breakthrough on Activated Carbon Sorbents
An extensive series of studies was performed at the Energy & Environmental Research Center with mercury (Hgo) sorbents in a thin bed using combinations of various flue gas constituents. This work determined that all the sorbents exhibited breakthrough in about I hour in the full flue gas mixture, and the mercury emitted after breakthrough is an oxidized mercury species. Trapping of the oxidized...
متن کاملEncapsulated liquid sorbents for carbon dioxide capture.
Drawbacks of current carbon dioxide capture methods include corrosivity, evaporative losses and fouling. Separating the capture solvent from infrastructure and effluent gases via microencapsulation provides possible solutions to these issues. Here we report carbon capture materials that may enable low-cost and energy-efficient capture of carbon dioxide from flue gas. Polymer microcapsules compo...
متن کاملMercury capture by regenerable sorbents under oxycoal combustion conditions
The largest source of mercury to the atmosphere in the world is the burning of fossil fuels, primarily coal. Electrical power plants are estimated to account for about 25% of the global anthropogenic mercury emissions to the atmosphere and industrial and residential heating for another 20% [1]. According to the European Environmental Agency (EEA), Spain is the third country among EU27 in mercur...
متن کاملElastic Layered Metal-organic Framework Sorbents for Carbon Capture
Introduction Elastic layered metal-organic framework (ELM) adsorbents exhibit a flexible two-dimensional latent porous crystalline structure. ELMs undergo abrupt reversible gated sorption transitions from an empty collapsed structure to a filled expanded porous state through cooperative adsorption of guest molecules between layer planes. Gated adsorption has been observed for methane, nitrogen,...
متن کاملAn X-ray photoelectron spectroscopy study of surface changes on brominated and sulfur-treated activated carbon sorbents during mercury capture: performance of pellet versus fiber sorbents.
This work explores surface changes and the Hg capture performance of brominated activated carbon (AC) pellets, sulfur-treated AC pellets, and sulfur-treated AC fibers upon exposure to simulated Powder River Basin-fired flue gas. Hg breakthrough curves yielded specific Hg capture amounts by means of the breakthrough shapes and times for the three samples. The brominated AC pellets showed a sharp...
