Abstract

This paper studies the chemical activation of mesocarbon microbeads in order to obtain activated carbons with controlled porosity. The effect that the activating agent (NaOH and KOH), the alkaline hydroxide/mesophase pitch ratio, and the activation temperature had on the characteristics of activated carbons was studied. Activated mesocarbon microbeads have been characterized using optical microscopy, atomic force microscopy (AFM), X-ray diffraction (XRD) and BET surface area analysis.

Keywords
