When the intra-particle mass transfer rate plays an important role in the adsorption process, it is desirable to reduce the particle size in order to reduce the length for mass transfer within the particle, and increase the surface area of the adsorbents. On the other hand, the reduced particle size increases the pressure drop across the adsorption bed. When the pressure of the system is low, the increase in pressure drop can significantly impact the power consumption of the PSA system. Therefore, the size of the particles cannot be too small, either.
