A numerical study of pellet model consistency with respect to molar and mass average velocities, pressure gradients and porosity models for methanol synthesis process: Effects of flux models on reactor performance

► The mass- and mole based pellet models are not completely consistent. ► The mass- and mole based pellet models differ by less than 2%. ► This small deviation is due to model equations are not fully consistent. ► The dusty gas model is most computationally expensive.
