This research line focuses on the development of catalytic and non-catalytic multiphase reactor systems that use rotation to create high gravity and high shear conditions. These conditions lead to excellent interphase mass transfer, excellent intra-phase mixing, and excellent fluid-to-wall heat transfer. Applications are especially in (exothermic) fast reactions that are interphase mass transfer limited, are mixing limited, or are heat transfer limited. Additionally, in a high gravity field two phases with different density can be contacted countercurrently, which opens up possibilities for separation processes. Thus, distillation (gas-liquid), extraction (liquid-liquid), and crystallization (liquid-solid) become feasible. The two main reactor concepts that our research focuses on are the ‘spinning disc reactor’ and the ‘rotating packed bed reactor’.
