Abstract

Abstract: Three kinds of surface carbon species (Cα, Cβ, and Cγ) were mainly originated from CH4 decomposition. Cα was an active carbide carbon and could be eliminated with CO2. Both Cβ and Cγ were inactive graphitic carbon and difficult to be eliminated with CO2.

Key words: methane, carbon dioxide, reforming, carbon deposition, hexaaluminate, lanthanum, nickel, aluminum, composite oxide
