Abstract: A rotating foam reactor(RFR) is a novel kind of stirrer tank reactor, which replaces the traditional agitator blade by donut-shaped foam block. This structure can improve effectively mass transfer process between phases. In addition, the foam block can be as support for catalyst deposition to reduce the consumption of catalysts in heterogeneous catalysis reaction. Therefore, RFR is a potential alternative to heterogeneous stirrer tank reactor or slurry reactors, and will have a broad application prospect. This study elaborates on the structure and characteristic of multiphase in an RFR. Research progress on the characteristic of multiphase flow and mass transfer performance are introduced. Besides, a comparison of mass transfer efficiency between RFRs and the general multiphase reactors are presented. In terms of application, the strengthening characteristic and advantages of adopting an RFR in heterogeneous reaction processes, such as hydrogenation of styrene and glucose oxidation are analyzed. The results indicate that an RFR can reduce energy consumption and improve utilization of raw materials in chemical processes. Some other reactors with porous agitator blades similar with RFR are introduced, and their advantages and characters are analyzed and compared. Finally, the insufficient of study and the development direction of RFRs are prospected.
