Bubble column reactor with dispersing devices

Abstract

A bubble column reactor with at least one radial dispersing device to radially sparge a gas phase into a liquid phase in the bubble column. The reactor comprises four parts: bubble column body 4, radial dispersing device, a mounting plate, and a head plate. The radial dispersing device is employed to radially disperse the gas phase into the liquid phase. It has a porous wall and an outer threaded port 2 and is vertically installed in the bubble column 4. A mounting plate is employed to allow the dispersing devices 1 to be vertically installed. A head plate 8 is employed to cover the bubble column 4 and have ports 9 for sampling, exhaust gas and sensors. The bubble column reactor according to this invention provides advantages in that it can generate small bubble sizes, thus increase the residence time of the gas phase even under relatively high gas velocities and also relatively high viscosities of the liquid reactant, thereby improving the mass transfer performance of the reactor.
