Patent ID: 7100905

Claim:
A reactor for gas/liquid or gas/liquid/solid reactions having a vertical longitudinal axis and an inlet for a liquid or liquid/solid feed stream in the upper region of the reactor and an inlet for a gaseous stream in the lower region of the reactor, comprising one or more chambers arranged above one another in the longitudinal direction, where each chamber is bounded at the bottom by a liquid-tight bottom plate, each chamber is connected via a liquid overflow to the interior space of the reactor below the liquid-tight bottom plate bounding the chamber and a liquid product stream is taken off via the liquid overflow of the bottommost chamber, the gas space below each liquid-tight bottom plate is connected to the chamber located immediately above it by one or more gas inlet tubes which opens into a gas distributor module provided with openings for exit of gas below the liquid surface in the chamber, and each chamber is provided with at least one guide plate which is arranged vertically around each gas distributor module and whose upper end is below the liquid surface and whose lower end is above the liquid-tight bottom plate of the chamber and which divides each chamber into one or more spaces into which gas flows and one or more spaces into which gas does not flow, wherein the gas distributor module is made up of straight tube sections, wherein each gas distributor module is formed by a vertical tube section which in each case encloses the upper end of the gas inlet tube and to which one, two or more horizontal tube sections which have openings for exit of gas are connected.
