Abstract

Activated carbon fibers (ACF) were prepared from poly(acrylonitrile) (PAN) precursor fibers by two methods: steam activation at 650-1000 °C and KOH activation at 600-800 °C. Steam activation yielded relatively poorly developed porosity regardless of the activation temperature, maintaining a low surface area (around 700 m² g^-1) at very high burn-off, while KOH activation provided high porosities above 700 °C. However, at ratios of KOH to fiber greater than 1:1 wt/wt, the fiber morphology was destroyed. The SO₂ conversion activity of the ACF was studied in the presence of oxygen and water. The activity was higher for as-produced KOH-activated samples (approximately 9 μmol SO₂ g^-1 min^-1) than for steam activated fibers (approximately 4 μmol SO₂ g^-1 min^-1), and correlated with lower oxygen content in the product fibers. The ACF were also used to manufacture composites. Composites retain the catalytic activity of the parent ACF.
