在过去的10到15年里，微反应技术已经成为学术界和工业界对多相过程强化的越来越感兴趣的技术。在广泛的应用可能性中，快速、高度放热和/或传质受限的气-液反应受益于过程小型化。本文综述了具有封闭和开放微通道的气液微反应器中流体力学和传质的最新研究，降膜式微反应器，并进行了比较。特别注意泰勒或弹状流在封闭的渠道，因为这种制度似乎是最适合于实际工程应用。
Over the last ten to fifteen years, microreaction echnology has become of increased interest to both academics and industrialists for intensification of multiphase processes. Amongst the vast application possibilities, fast, highly exothermic and/or mass transfer-limited gas-liquid reactions benefit from process miniaturization. Recent studies of hydrodynamics and mass transfer in gas-liquid microreactors with closed and open microchannels, e.g., falling-film microreactors, are reviewed and compared. Special attention is paid to Taylor or slug flow in closed channels, as this regime seems to be most adapted for practical engineering applications.
