Abstract
The gasification of graphite by carbon dioxide was studied under atmospheric pressure in a fixed bed reactor in the temperature range of 1173–1773 K, CO2 partial pressures 2–10 kPa and gas flow rate 0·5–2·0 L min−1. Iron presented in a small amount in graphite ash had a catalytic effect on the gasification reaction at 1373 K; this effect was weaker at 1473 K due to the melting of iron saturated with carbon. The gasification rate increased with increasing CO2 partial pressure and total gas flow rate.
