Abstract: A process and an apparatus for producing a homogeneous mixture of a gaseous aromatic hydrocarbon and an oxygen-containing gas for catalytic gas-phase reactions, in particular a homogeneous mixture of gaseous o-xylene and/or naphthalene and air for preparing phthalic anhydride, are provided. The liquid aromatic hydrocarbon is atomized to form droplets having a diameter of less than 1 mm and injected into an oxygen-containing gas stream (12) preheated to above the boiling point of the aromatic hydrocarbon. According to the invention, the liquid aromatic hydrocarbon is atomized by means of nozzles (15) which form a hollow cone (16), preferably by means of swirl nozzles. The o-xylene/air mixture is advantageously produced in a chamber which is bounded by side walls (18) heated to above the boiling point of the hydrocarbon.

Abstract: A supported catalyst containing vanadium and titanium and/or zirconium comprising a ring-shaped carrier having an external diameter of from 7.3 to 8.6 mm, a length of from 5.3 to 7 mm and a wall thickness of from 0.1 to 2 mm, and an active composition, applied thereto, of from 1 to 30 per cent by weight of vanadium pentoxide and from 70 to 99 per cent by weight of titanium dioxide and/or zirconium dioxide. This catalyst can be used for the manufacture of phthalic anhydride by catalytic oxidation of o-xylene or naphthalene with air.

Abstract: Production of a homogeneous mixture of an aromatic hydrocarbon vapor and an oxygen containing gas for catalytic gas phase reactions, comprises spraying droplets of the liquid aromatic hydrocarbon having a diameter of less than 1 mm, into the oxygen containing gas stream, heated to above the b.pt. of the hydrocarbon, by means of nozzles, preferably rifled nozzles to form a hollow cone. An Independent claim is included for a device for the production of the vapor mixture (I) having gas channels (11) for the pre-heated oxygen containing gas stream (12); a spray device (13) opening into one channel (11) for a liquid aromatic hydrocarbon stream whereby the spray device (13) has rifled nozzles (15) and the gas channels (11) have walls (18) that extend at least away from the nozzles (15) and are heated to at least the b.pt. of the hydrocarbon.
