Production and Applications of Activated Carbons

Development and characterization of activated hydrochars from orange peels as potential adsorbents for emerging organic contaminants

“…Moreover, there are some differences on the way the different activating agents react with the carbon, and this in turn affects the surface features of the final adsorbent. For example, HC-A developed common characteristics of a microporous material, with a slight contribution of mesoporosity, and a relatively large S BET , in coherence with previous works dealing with air activated carbons (Rodriguez Reinoso, 2002). On the other hand, even when activation with CO 2 did not provoke an important increase in its S BET , it can be seen that the isotherm obtained for HC-C was the only one that displayed exclusively type I characteristics, indicating the development of an essentially microporous structure.…”

“…ACs are usually produced by physical or chemical activation. Both processes require a pyrolysis stage either prior or after the reaction with the gasifying or oxidizing agent (Rodriguez Reinoso, 2002). Usually the pyrolytic stage involves the use of high temperatures (above 600°C) as well as the use of high purity inert gases.…”

Copper on activated carbon for catalytic wet air oxidation

“…Almost any carbonaceous material, with high carbon content and low proportion of inorganic components, can be used as precursor for the preparation of activated carbons 9 . In this work, activated carbons were obtained from industrial wastes (apricot core and grape stalk) of San Juan, Argentina.…”

Evaluation of a mixed geometry model for the characterization of activated carbons

“…due to their versatility and low cost (Marsh and Rodríguez-Reinoso 2006;Rodríguez-Reinoso 2002). The development of more appropriate and efficient AC for different applications is being the subject of an important amount of research (Lee et al 2006;Prauchner and Rodríguez-Reinoso 2008;Rios et al 2009;Santos et al 2010).…”
