Abstract: What is described is a process for starting up a gas phase oxidation reactor for oxidation of o-xylene to phthalic anhydride, said reactor comprising at least one catalyst layer and being temperature-controllable by means of a heat carrier medium, wherein a) the catalyst layer is interrupted by a moderator layer which is less catalytically active than the catalyst layer or is catalytically inactive, b) a gas stream is passed through the reactor with an initial loading of o-xylene and at an initial temperature of the heat transfer medium, c) the loading of the gas stream is increased to a target loading and, in parallel, the temperature of the heat transfer medium is lowered to an operating temperature. The introduction of the moderator layer allows the loading to be increased more rapidly and the startup time to be shortened.

Abstract: The present invention relates to a method for gas phase oxidation, wherein a gaseous flow comprising aromatic hydrocarbon and molecular oxygen is conducted through two or more catalyst layers. The present invention further relates to a catalyst system for gas phase reaction using an upstream layer. The product of diameter times the height, or the volume, of the inert and/or catalyst rings disposed upstream is less than at least one of the subsequent catalyst layers, or the quotient of the surface per volume of the upstream inert and/or catalyst rings is greater than at least one of the subsequent catalyst layers.
