The adsorption and the desorption of SO: on active carbons is studied in relation to the surface characteristics of the carbons. Surface basic groups (with pyronic or pyronic-like structure) greatly increase the adsorption of SO,, that can be divided into two forms. one weakly and the other strongly
PAN-based carbon fibers were stabilized under various tensions in the presence of air at 230ยฐC and sequentially activated at 950ยฐC following carbonization. The prepared carbon fibers were tested for their SO2 adsorption capacity using a thermogravimeter. The magnitude of tension during stabilization
