Engineering 2020, Volume 6, Issue 6,   Pages 680-687 doi: 10.1016/j.eng.2019.12.018

Abstract:

Herein, we report on the effect of a high gravity field on metal-free catalytic reduction, takingefficiency was attributed to the much higher turbulent kinetic energy and faster surface renewal rate in the high-gravityThe structure of the 3D metal-free catalysts was stable during the reaction process under a high gravityIn the other model reaction, the rate of MB degradation also increased as the high gravity level increasedThese results demonstrate the potential to use a high-gravity rotating packed tube reactor for the process
