Abstract
L'invention concerne un procédé de synthèse d'acide nitrique (100) comprenant les étapes de traitement d'ammoniac (1) en présence d'oxygène (2) ou d'air à une étape d'oxydation catalytique (3) pour produire un gaz brûlé (4), soumission du gaz brûlé (4) à une étape de décomposition catalytique (5) pour produire un flux de gaz appauvri en n2o (6), soumission du flux de gaz appauvri en n2o (6) à une étape de refroidissement (9) pour produire un flux refroidi (11) et soumission dudit flux refroidi (11) à une étape d'absorption (23) en présence d'eau (50) pour produire un acide nitrique (12) et un gaz résiduaire (13) retenant des nox ; l'étape de décomposition catalytique (5) est réalisée à une température comprise entre 450°c et 700°c sur un ou plusieurs catalyseurs à base de zéolites de fer déposés, revêtus ou co-extrudés sur un support de catalyseur pourvu de canaux perméables aux gaz.
