ABSTRACT:
This invention is a catalyst and a process using that catalyst for oxidizing hydrogen bromide to form elemental bromine. The inventive catalyst composition comprises cerium bromide on certain zirconia containing supports. The zirconia support, preferably largely in the baddeleyite phase, stabilizes the cerium bromide catalyst against cerium oxide formation at operating temperatures and gives the catalyst excellent activity at lower temperatures.
