  • Abstract: Surface structures and reactivities of carbons gasified in N~2O and in O~2 are compared in this study. The carbon employed was derived from pyrolysis of phenol-formaldehyde resins. It was found that greater surface area and pore volume are created for the carbon gasified in O~2 than that in N~2O. At high extents of burn-off the carbon gasified in N~2O shows a larger mesopore volume than that in O~2. The reactivity per unit surface area of the carbon in N~2O decreases with the extent of burn-off, while that in O~2 remains relatively constant at various extents of burn-off. Surfaces in carbon micropores do not appear to be fully utilized in the N~2O-carbon reaction. It is confirmed that standard N~2 or CO~2 surface area is not a proper characterization of the reactive surface area of carbon gasified in N~2O.
