This chapter reviews the art and science involved in understanding the multiscale multiphase phenomena that affect the performance of trickle bed reactors. Their application areas, the traditional approach to their design and scaleup, and some commonly encountered problems in practice are discussed. The foundations for rational scaleup are introduced. The recent attempts to develop a multiscale science-based approach to scale up and design of these reactors is summarized at the end.
