Abstract: The invention relates to a catalyst for producing an α,β-unsaturated carboxylic acid by gas phase oxidation of an α,β-unsaturated aldehyde, comprising a moulded body support having an active material applied thereto, characterised in that the active material covering q is a maximum 0.3 mg/mm
2 , Q being the active material part of the catalyst in wt.-% and S
m being the specific geometric surface of the moulded body support in mm
2 /mg. The invention also relates to a method for producing said catalyst and to a method for producing an α,β-unsaturated carboxylic acid by gas phase oxidation of an α,β-unsaturated aldehyde on a fixed bed catalyst which contains the bulk material of the catalyst. Due to said catalyst, the over-oxidation into CO
x is reduced and the selectivity of the formation of acrylic acid is increased, whilst maintaining a continuous high yield in acroleine.

Abstract: The invention relates to a method for introducing annular shaped shell catalysts K into a reaction tube of a tube bundle reactor. According to the invention, during the production of the annular-shaped shell catalysts K, pairs of annular-shaped shell catalysts K that are formed are separated at least partially from the annular-shaped shell catalysts prior to introducing into the reaction tube.
