Abstract
Process for the selective oxidation of ethane to ethylene and/or acetic acid, and/or the selective oxidation of ethylene to acetic acid, by contacting ethane and/or ethylene with a molecular oxygen-containing gas at elevated temperature in the presence of a spray-dried supported catalyst composition. The supported catalyst composition includes molybdenum, vanadium and niobium metal components, supported on a support comprising alpha-alumina. The supported catalyst is prepared by forming a slurry of the metal components and alpha-alumina support particles or an alpha-alumina support precursor, and spray-drying the slurry.
