摘要： A catalyst for gas phase oxidations comprises an inert support and a catalytically active material which comprises vanadium oxide and titanium dioxide and has been applied thereto. The titanium dioxide has a content of sulfur compounds, calculated as S, of less than 1000 ppm and a content of calcium compounds, calculated as Ca, of less than 150 ppm. The catalyst has a relatively high activity and/or selectivity and thus enables relatively high yields of the desired target product, for example phthalic anhydride. Also described is a process for preparing phthalic anhydride, wherein a gas stream which comprises molecular oxygen and o-xylene, naphthalene or mixtures thereof is contacted with the catalyst.

摘要： In a process for controlling a gas phase oxidation reactor for preparation of phthalic anhydride, by passing a gas stream which comprises an aromatic hydrocarbon and molecular oxygen through a multitude of reaction tubes arranged in the gas phase oxidation reactor, each of which comprises a bed of at least one catalyst and the temperature of which can be controlled by means of a heat transfer medium, at least one control parameter is measured and correcting interventions for control of the control parameter are determined, the at least one control parameter comprising the phthalic anhydride yield and the correcting parameter used being the temperature of the heat carrier medium. Over at least 90% of the lifetime of the catalyst, the change in the correcting parameter is limited to a maximum of 0.5 K within a period of 30 days. In this way, the cumulated phthalic anhydride yield over the lifetime of the catalyst is maximized.

摘要： 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.
