This work compared the activation reactivities of different carbonized materials to justify the adsorption properties of the activated carbons prepared under the same steam activation conditions but from different raw materials
including rice husk
sawdust and lignite.The results showed that the activation reactivity of biomass feedstock was higher than lignite
and the activation rate of carbonized material varied in a descending order of ash-removed rice husk
sawdust
rice husk and lignite.Characterizing the carbonized materials by ultimate and proximate analysis
BET
SEM
XRD
FTIR
and XPS was performed to clarify further the reason for such different activation characteristics.It was found that the higher the volatile component and organic oxygen and the lower the ash content in the raw material
the easer it would be to produce high quality activated carbon via a short-time activation.
