Isothermal Kinetics of Metallurgical Coke Gasification by Carbon Dioxide

Isothermal Kinetics of Metallurgical Coke Gasification by Carbon Dioxide In the present study, the kinetics of isothermal gasification of metallurgical coke by carbon dioxide was investigated through the use of thermogravimetry. For gasification of carbonaceous materials, two typical conversion models, i.e. the John-Mehl-Avrami model (JMA) and the random pore model (RPM), were employed to portray the reaction process. Compared with the RPM model, the JMA model was found to be the suitable conversion model after the further comparison of the Arrhenius parameters calculated from these two conversion models. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Coke and Chemistry Springer Journals

Abstract

In the present study, the kinetics of isothermal gasification of metallurgical coke by carbon dioxide was investigated through the use of thermogravimetry. For gasification of carbonaceous materials, two typical conversion models, i.e. the John-Mehl-Avrami model (JMA) and the random pore model (RPM), were employed to portray the reaction process. Compared with the RPM model, the JMA model was found to be the suitable conversion model after the further comparison of the Arrhenius parameters calculated from these two conversion models.
