A method based on particle‐resolved CFD is built and validated, to calculate the fluid‐to‐particle mass and heat transfer coefficients in packed beds of spheres with different tube‐to‐particle diameter ratios (N) and of various particle shapes with N = 5.23. This method is characterized by considering axial dispersion. The mass and heat transfer coefficients increase by 5%–57% and 9%–63% after considering...
Using a catalyst support with optimal pore network and pellet structures is critical to the success of an industrial heterogeneous catalyst. This work optimizes the catalyst support of a dry reforming of methane catalyst at packed bed reactor level, that is, effects of concentration and temperature gradients in the reactor are accounted for. Meanwhile, the optimization at reactor level is also compared...
