| 摘要 |
The invention relates to a method for producing hydrogen peroxide by converting hydrogen and oxygen in the presence of a liquid reaction medium and a particulate noble metal support catalyst in a fixed-bed reactor, wherein the liquid reaction medium and a gas phase containing hydrogen and oxygen flow against the fixed bed from below. The fixed bed is arranged in the reactor such that the volume of the fixed bed expands by 1 to 10% in the operating state relative to a rest state without a flow against the fixed bed. As a result of the fixed bed expansion according to the invention, the fixed bed can be prevented from clogging due to abrasions on the catalyst. |
