Abstract: The invention relates to an apparatus for introducing loose materials, in particular catalysts made up of small bodies, into tubes, containers and the like which has a number of charging units and a transport device (1) which moves all the charging units simultaneously. To achieve reliable and exact relocation of the filling units, the transport device comprises a baseplate (2) which can be moved back and forth, at least one piston-cylinder unit (3) fastened to the baseplate and one or more transport claws (5), with the transport claws being operatively connected to the piston-cylinder unit, being rotatable about a common axis and having their free end projecting through openings (6) in the baseplate into tubes (7), containers and the like and the length of the openings in the direction of movement of the baseplate being equal to or greater than the stroke of the piston-cylinder unit.

Abstract: A method is for producing monolithic substrate catalysts and for their use in the gas phase oxidation of hydrocarbons. The catalysts are obtained by coating the catalyst substrate with a suspension that includes a catalytically active compound and one or more surfactants of the general formula RnYmX. R represents the hydrophobic part of the surfactant, with n being 1, 2 or 3. Y represents the hydrophobic part of the surfactant, with m being 0, 1, 2, or 3 and X represents the hydrophilic head group of the surfactant.
