摘要: A mathematical model has been proposed for describing the carbothermic nitridation of carbon/metal oxide pellet in a stream nitrogen. Based on model, dimensionless governing equations were derived to represent non-isobaric system. Effects following five parameters conversion solid C and yield E have found be similar that an isobaric system: reaction/diffusion ratio σ2, reactivity ratios β1 β2, reactant amount γ Sherwood number NSh. The reaction rate was high when value viscous constant B* large. system generally lower than
