Abstract
A fixed bed catalytic reactor having a porous bed of catalyst particles contained in a closed reactor shell, comprising PA0 inlet means for introducing a downwardly flowing mixed stream of gas and liquid reactants; PA0 phase separator means for receiving said mixed stream and directing liquid onto the porous catalyst bed, said separator means being disposed within the reactor shell between said inlet means and said porous catalytic bed; PA0 said separator means comprising an upper foraminous wall having a series of gas outlets permitting a substantially-gaseous phase to escape outwardly from the separator means into an upper reactor portion, and lower liquid distribution means for receiving a stream of substantially liquid phase and dividing said liquid phase into a plurality of spaced-apart liquid streams directed toward the porous catalyst bed; and PA0 means for recovering gaseous and liquid reaction products from the reactor shell. The phase separator-distributor is particularly useful for retrofitting a reactor to accommodate mixed flow without requiring welding internal structures onto the reactor shell. In a petrochemical complex, such separation and distribution system is ad…
