Summary

Mixing processes affect chemical reaction rates, yield and selectivity. These effects are discussed in depth with examples. Homogeneous and heterogeneous reactions are discussed for various reactor types - pipe, static mixer, and stirred vessel. The chapter is divided into four parts: 1. a presentation of the experimental and theoretical basis for the interaction of mixing processes with reaction; 2. application of these ideas to reactor scale up for homogeneous and heterogeneous reactions; 3. approaches to scaling up such reactors which have proven successful in industrial research and development groups and 4. simulation of mixed reactors with discussion of how such simulations match corresponding experimental measurements. The chapter gives practical advice on how to solve yield problems caused by inadequate mixing and make decisions regarding scale-up. Simulation may be used as a tool for scale-up and design of mixed reactors, primarily as a way to augment or direct experiments. Extensive examples are presented in the chapter.
