Abstract: The slurry reactor is an important type of gas-liquid-solid multiphase reactors. It has the advantages of simple construction, good mass and heat transfer performance, and feasibility of on-line addition or replacement of catalysts. It has received attentions from both academic and industrial circles. This paper reviews the study of hydrodynamics of slurry reactor, including flow regime, gas holdup, bubble behavior, and mass and heat transfer rates. The effects of temperature, pressure and liquid properties on the hydrodynamics are discussed. Novel slurry reactors, such as multi-stage slurry reactor and slurry reactors with internals are introduced. The industrial applications of slurry reactor on bulk chemical and fine chemical industries and environmental processes are summarized. Perspectives are given on the potential application and future research of slurry reactors.

Key words: multiphase reactor, hydrodynamics, transport processes, industrial application
