Abstract

This research investigates heating in microreactors by application of microwave fields. Problems encountered with microwave heating equipment currently used in microwave enhanced chemistry research are: hardto-predict electromagnetic field patterns, the lack of controllability and optimizabillity of heat generation, and low utilization efficiency. This conflicts with the highly optimized processing conditions that are characteristic for microreactor systems. These issues are related to the resonant nature of microwave fields. To avoid these problems a novel coaxial traveling microwave field applicator is proposed here and a method to optimize it is demonstrated.
