The adsorption and desorption properties of viscose-based activated carbon fiber (VACF) for organic gases with different polarities were studied.

Among the storage technologies of automotive fuel gases (hydrogen and nature gas), adsorption storage is a promising technology for the low density and fast desorption of adsorption storage materials.

The thermal desorption spectrum (the desorption rate VS sample temperature), the desorption action order and the desorption activation energy have been obtained for main kinds of desorpted gases.
