EFFECT OF STEAM AND CARBON DIOXIDE ACTIVATION ON THE MICROSTRUCTURE OF ACTIVATED CARBON FABRICS

摘要

In this study, PAN-based activated carbon fabrics were developed from continuous carbonization and activation at temperatures ranging from 900 to 1100°C in steam and carbon dioxide. The microstructure changes in ACFs during different activation processes were studied using wide-angle X-ray diffraction and Raman spectography. The samples were analysized with in original form (fabrics) and powder form, in order to examine both the surface and inner structures.
