Fecha de publicación: | 15-ene-2015 | Editor: | Elsevier | Citación: | Chemical Engineering Journal 260: 463-468 (2015) | Resumen: | The direct chemical activation of pitch-based stabilized carbon fibers (uncarbonized) with a conventional activating agent (KOH) has been studied for the first time. Unlike the traditional activation method, this shorter route merges the carbonization and activation steps into one simple thermal treatment. It also requires up to a 70% less activating agent for a given porous structure, which can reach values of SBET>1700m2g-1. In addition, the overall yield of the activation process is increased. The advantages obtained open up the way to a novel environmentally friendly industrial method of preparing activated carbon fibers. | Versión del editor: | https://doi.org/10.1016/j.cej.2014.08.104 | URI: | http://hdl.handle.net/10261/345522 | DOI: | 10.1016/j.cej.2014.08.104 | ISSN: | 1385-8947 |
