摘要： Process for preparing oligomers of alkenes having from 4 to 8 carbon atoms from a feed stream comprising such alkenes or hydrocarbon streams in which such alkenes are present over a nickel-containing, heterogeneous catalyst in n successive adiabatically operated reactors, where n is 2 or an integer greater than 2, at from 30 to 280° C. and pressures of from 1 to 300 bar, where the feed stream has a temperature Tin when it enters the first reaction zone, experiences a temperature increase in each reaction zone and, if this temperature increase is more than Tin+20° C., is brought to a temperature in the range Tin±20° C. before it enters a subsequent reaction zone, wherein the feed stream is divided and the feed substreams obtained in this way are fed to the 2 reactors, or if more than 2 reactors are used to at least 2 of the reactors, with addition of fresh feed in such a way that the temperature in one of the reactors is at most 20° C. higher than that in each of the other reactors used.

摘要： A process for preparing phthalic anhydride by gas-phase oxidation of xylene, naphthalene or mixtures thereof over two different fixed-bed catalysts arranged in zones in a shell-and-tube reactor which is thermostated by means of a heat transfer medium is carried out so that the maximum temperature in the second catalyst zone in the flow direction is at least 52° C. lower than the maximum temperature in the first catalyst zone. The process of the present invention makes it possible to prepare phthalic anhydride in high yields under conditions relevant to industrial practice.
