Abstract: Novel coated catalysts and a process for their preparation by atomizing a mixture of water and a vanadium-V compound, with or without other metal compounds, and applying this mixture to carrier particles which are themselves in motion, drying the coating and subjecting the catalyst particles, which are themselves in motion, to repeated brief treatment with a flame or plasma, followed by rapid cooling, defined temperatures and rates of coating being employed. The catalysts may be used with advantage for the preparation of anthraquinones by oxidation of indans.
