Fecha de publicación: | jul-2009 | Editor: | Elsevier | Citación: | Fuel 88(7): 1194-1200 (2009) | Resumen: | Recent research has shown that certain fly ash materials produced in coal combustion for power generation have an affinity for the mercury compounds present in flue gases. However, the exact nature of Hg–fly ash interactions is still unknown and the different variables that influence mercury adsorption need to be identified. In this work the microscopic components of fly ashes derived from the combustion of different types of feed blends of different coal rank and mercury adsorption were investigated. The aim of this research was to establish relationships between Hg retention and the type of unburned carbons present in various fly ashes. The fly ashes and fly ash fractions studied were used as sorbent beds for high mercury concentrations, conditions in which mercury retention is highly favored. From the results obtained it was confirmed that the role of the unburned carbon components in mercury capture may depend, among other factors, on the type of unburned carbon. Fly ashes capture different species of mercury depending on their nature and the type of anisotropic particles. | Versión del editor: | http://dx.doi.org/10.1016/j.fuel.2007.07.029 | URI: | http://hdl.handle.net/10261/108532 | DOI: | 10.1016/j.fuel.2007.07.029 | ISSN: | 0016-2361 | E-ISSN: | 1873-7153 |
