Title: Catalytic gasification of graphite or carbon. Quarterly report, October 1-December 31, 1984

Abstract

Adsorption experiments with CO or CO/sub 2/ on graphite using labelled carbon have shown an exchange of carbon between graphite and CO at very high temperatures, but not between graphite and CO/sub 2/. Since /sup 13/CO/sub 2/ is desorbed from adsorbed /sup 13/CO at 730K (437/sup 0/C) and below, it must be formed by disproportionation, leaving some carbon on the graphite surface. In the gasification of graphite over KOH/NiO catalysts at 860K (567/sup 0/C) more hydrogen and less CO and methane are observed than corresponds to equilibrium. CO/sub 2/ is a major product along with hydrogen. To determine whether methane is a major primary product which is then decomposed by steam reforming, methane was added to the steam feed. The vast majority (95+%) of the added methane was recovered in the product, s
