概要
- 論文の詳細を見る
The sulfurization of sintered reduced iron in a hydrogen gas stream containing hydrogen sulfide was investigated. To describe the behavior of this reaction system accompanied by significant decrease in porosity of reacting solid, the volume reaction model was modified in due consideration of the variation of effective diffusivity. Observed overall reaction rate under the influence of diffusion limitation was well represented by this model. The intrinsic rate constant was then separated from the overall rate data and correlated in an Arrhenius-type equation. The rate process is also discussed in detail in relation to the shrinking core model and the accuarcy of its application is dealt with.
