ABSTRACT:
In a process for preparing an aqueous and/or alcoholic solution of hydrogen peroxide by reaction of hydrogen and oxygen in a trickle-bed reactor over a supported catalyst including a noble metal, the apparent flow direction of the gas stream and the apparent flow direction of the liquid stream are not parallel to one another. The apparent flow direction of the gas stream preferably runs radially from the longitudinal axis to the circumference of the reactor. The process allows high gas throughputs with a small pressure drop.
