摘要： The invention relates to a process for producing a catalyst for gas-phase oxidations, which comprises weighing a particulate inert support having a total mass of Msupport into a fluidized-bed apparatus, providing an aqueous suspension of a catalytically active material or sources therefor and a binder having a binder content of Bsusp, fluidizing the inert support by introduction of a gas stream heated to a temperature of Tgas at a flow rate of Qgas, and spraying the suspension at a rate of Qsusp onto the fluidized inert support. When Qgas, Qsusp, Bsusp, Msupport and Tgas are selected within the ranges 3000≦Qgas [m3/h]≦9000, 1000≦Qsusp [g/min]≦3500, 2≦Bsusp [% by weight]≦18, 60≦Msupport [kg]≦240. 75≦Tgas [° C.]≦120 so that a parameter K defined as K=0.020 Qgas−0.055 Qsusp+7.500 Bsusp−0.667 Msupport+2.069 Tgas−7satisfies the relationship 127.5≦K≦202, high-quality coatings can be produced and the formation of twins made up of support particles adhering to one another can be avoided.
