Abstract
A hydrogen production facility having equipment with a nitridation protective layer is provided. The hydrogen production facility can include a reformer configured to catalytically convert a feed stream into a product stream comprising hydrogen, the reformer having a plurality of catalyst tubes and a plurality of burners configured to provide heat to the catalyst tubes; means for providing the feed stream to the reformer from an ammonia source, wherein the feed stream comprises at least 90% of ammonia, wherein the plurality of catalyst tubes comprise a nitridation protective layer on an inner surface of the catalyst tubes.
