Abstract
Ammonia oxidizers are disclosed that can include gas distributors and distribution rings to improve the distribution of the flow of a gas feedstream across a catalyst bed in the ammonia oxidizer. The gas distributors include circular plates that have holes through which the gas feedstream is distributed across the catalyst bed. In some examples, the gas distributors also have a sidewall. The distribution rings are attached to the inner wall of the ammonia oxidizer at a predetermined distance below the gas distributor.
