The invention relates to a method for producing acetic acid from ethane and oxygen on a fixed bed catalyst, characterized in that a reactor cascade with an oxygen feed between the reactor levels is used. This particularly advantageous method provides high conversion rates, highly pure acetic acid and low ethylene and carbon monoxide formation.
L'invention concerne un procédé de fabrication d'acide acétique à partir d'éthane et d'oxygène, sur catalyseur à lit fixe, caractérisé en ce qu'on utilise une cascade de réacteurs avec alimentation en oxygène entre les étages de réacteurs. Le procédé est particulièrement avantageux en raison des taux de conversion élevés, de la pureté de l'acide acétique obtenu et de la faible formation d'éthylène et de monoxyde de carbone.
