There is a small amount of NOx produced due to the high operating
temperature of the reformer.  The numbers I've seen are between a 98%
and 99% reduction.  There is also significant (but again, much lower)
carbon monoxide emission.

Mostly they just emit carbon dioxide and water.  My only objection to
your claim was your use of the word "pure" to describe the steam
output.  "Mostly pure" would be more accurate.
