Kinetic Modeling of CO2 and H2O Gasification Reactions for Metallurgical Coke Using a Distributed Activation Energy Model

Yui Numazawa et al.

Summary: In this study, a distributed activation energy model (DAEM) was used to analyze the kinetic characteristics of CO2 and H2O gasification reactions for pulverized metallurgical coke. The results indicated that gasification occurs at the particle surface, with activation energy changing as the reaction progresses and being independent of particle size. The activation energies for CO2 and H2O gasification were found to range from 200-260 kJ/mol and 220-290 kJ/mol, respectively, with the frequency factor for H2O gasification being significantly higher than that for CO2 gasification.

Influence of Temperature and CO2 on High-Temperature Behavior and Microstructure of Metallurgical Coke

Mingyu Wang et al.

Summary: The study investigated the high-temperature behavior of metallurgical coke samples under the influence of temperature and CO2. Results showed changes in weight loss, strength, and reactivity index of coke samples under different conditions. The impact of CO2 and temperature on the carbon structure and pore structure of coke samples was observed, with temperature having a greater influence on pores than CO2. Multiple regression analysis indicated that carbon structure and pore number had the strongest impact on coke strength.
