Summary

This chapter discusses design features for both laboratory-scale and pilot-scale pretreatment reactor systems. The discussion of laboratory-scale pretreatment equipment focuses on simple batch systems, as continuous systems at the bench scale are difficult to implement and often require components that are not scalable or require unrealistically small feedstock particle sizes. Emphasis is placed on pretreatment equipment that can operate under process-relevant conditions, such as at reasonably high solids loadings. Design features of the various components of continuous pilot-scale biomass pretreatment reactors and associated ancillary equipment are discussed, including feedstock preparation and handling, pretreatment chemical introduction, pressurized biomass feeding equipment, pretreatment reactor conveyance systems and residence time control, pretreatment reactor discharge devices, blow-down tank design, and flash recovery systems. Examples of integrated continuous pilot-scale pretreatment reactor systems that incorporate these various equipment components are provided.
