Abstract

In the preparation of a catalyst for gas phase oxidations, particles for an inert support are weighed into a fluid bed with a total mass (MTrager). A fluid is prepared as an aqueous solution or suspension of a catalytically-active material, or source, preferably TiO 2 and/or V 2O 5, with a content (BSusp) of bonding agents. The inert support particles are fluidized by a gas flow with a controlled temperature (TGas) and flow (QGas). The suspension is sprayed on to the fluidized inert support at a given dosage rate (QSusp). The values are selected to give ranges of 3000=QGas[m3/h]=9000, 1000=QSusp[g/min]=3500, 2=BSusp[wt.%]=18.60=MTrager[kg]=240, 75=TGas[[deg]C]=120. The ranges are such that, for a parameter (K) where K=0.020QGas-0.055QSusp+7.500BSusp-0.667MTrager+2.069TGas-7, the relationship 127.5=K=202 is satisfied.
