    Abstract

    The reactivity of hydrogen adsorbed on Saran char is examined to characterize its properties and role in carbon gasification. In sequential D2-H2 gasification, H-D exchange is observed at 1120 K, supporting a hydrogasification mechanism of sequential, dissociative hydrogen adsorption on adjacent carbon sites. Char oxidation in O2 removes hydrogen at a rate slower than that at which the carbon is gasified, suggesting that hydrogen inhibits char reaction even in oxygen. Char oxidation at low temperature enhances the rate of subsequent hydrogen gasification by creating additional active silos and removing a portion of the adsorbed hydrogen.
