摘要：

The mechanical properties of a special formcoke were studied after reaction in CO2 and in CO/CO2 mixtures. The effects of iron- and potassium-catalyzed gasification were also investigated. The Young's elastic modulus, fracture toughness, and fracture surface energy were all observed to decrease with increasing amounts of reaction of the formcoke. These properties were observed to be strongly correlated to the final bulk density rather than to the particular reaction conditions.
