Descripción
Sumario:[EN] Arsenic and selenium are toxic element s present in coal in trace concentrations that may be emitted to the environment during coal conversion processes. However, it is possible to retain volatile arsenic and selenium compounds in the fly ashes originated by the process, the proportions retained depending on the characteristics of the ashes and process conditions. This work is focused on the capture of these elements in fly ashes in simulated coal combustion and gasification atmospheres in laboratory scale reactors.
