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.
Claims14
An HBr oxidation catalyst composition comprising cerium bromide present in at least a catalytic amount and a baddeleyite phase zirconia-containing catalyst support.
An HBr oxidation catalyst composition consisting essentially of:
- a. cerium bromide in an amount such that the overall cerium content of the composition is within the range of about 0.2 to 0.6 mmoles Ce/g of the overall composition, and
- b. a baddelleyite zirconia catalyst support.
