✦ Synopsis

The effects of dispersion of ultrafine a-FeOOH particles of pitch-based activated carbon fibers (ACF) on the adsorption characteristics against NO, SO,, and NH3 were examined at 303 K.

Also the micropore structures were studied by Nz adsorption at 77 K. The adsorption isotherms for not only Nz but also NO, SO,, and NH2 were analyzed by the DR plots. The dispersion of a-FeOOH markedly increased the amounts of adsorption for NO and NH, at lower pressure regions, but it did not increase the adsorption capacities for all adsorptives. The a-FeOOH dispersion enhanced the isosteric heat of adsorption for all adsorptives, in particular NH,.
