Three　commonly　used　distributors　(i.e.,　nozzle,　packed　bed,　and　foam)　were　introduced　into　a　multiphase　monolith　reactor　in　this　work　to　investigate　the　pressure　drop,　liquid　holdup　and　gas-liquid　distribution　performance　by　combining　experimentation　and　CFD　simulation.　The　experimental　results　showed　that　the　nozzle　distributor　exhibited　the　better　gas-liquid　phase　distribution　and　the　lowest　pressure　drop.　However,　so　far,　the　gas　and　liquid　velocities　at　the　top　of　the　monolith　bed,　which　are　crucial　for　the　transition　from　a　single　channel　to　bed　scale,　have　not　been　studied.　Thus,　a　discrete　phase　and　continuous　phase　coupling　3D　model　using　CFD　simulation　was　established　for　the　nozzle　distributor,　and　the　magnitude　and　distribution　of　the　gas　and　liquid　velocities　at　the　entrance　of　the　monolith　module　were　investigated.　The　simulation　results　showed　that　the　droplets＇　velocity　reaching　the　monolith　module　was　very　high　and　had　a　strong　influence　on　the　gas　velocity　distribution.　The　increase　in　superficial　gas　velocity　could　enhance　the　gas　distribution　to　some　extent.
