Abstract
A commercially available activated carbon (Norit Darco FGD) has been used to perform experimental runs . aimed to study the divalent mercury adsorption phenomena. The authors have already investigated about . this topic, carrying out several studies on mercury adsorption, both in metallic and divalent form, by using . activated carbon, on a laboratory scale apparatus. However this time their studies are focused on . adsorption of divalent mercury chloride vapors onto a solid carbon phase dispersed in a continuous phase; . so a new pilot scale plant necessitates. The new layout has permitted to investigate phenomena involved . varying the following parameters: first of all the temperature reactor (from 120 °C to 135 °C), then the initial . mercury concentration (c Hg. in. , 1000 to 2000 μg\/m. 3. ), finally the initial total gas flowrate (27.8 to 62.3 m. 3. \/h). . The carbon flowrate has been kept constant to 6 g\/h value. Results obtained are very encouraging, as the . activated carbon efficiency reaches up to 80% value.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
