Abstract: For the study of microwave chemistry, it is necessary to develop a
reactor with small-size and wide operating frequency band. This paper presents
a novel microwave coaxial reactor. Its main part is a coaxial cavity, and the
input end is a coaxial port filled with PTFE, and the other end is a short
circuit terminal. Two orifices which are designed as cut-off waveguides for
microwave are attached to the cavity as passageway of sample solutions, so the
reactor can treat the samples continuously. The distributions of
electromagnetic field and temperature of this novel microwave coaxial reactor
used for heating edible vegetable oil at 915 MHz and 2450 MHz are simulated
with finite-element method multi-fields coupling analysis. It is easy to find
out that this novel microwave coaxial reactor could work properly over a wide
frequency band. Also, the operating frequency could be chosen over a wide
frequency band to get the optimal reaction effect to meet the requirements of experiments.
