Title

(DE) Verfahren zur Herstellung von Methanol

Abstract

(DE)

Bei der Herstellung von Methanol mittels eines katalytischen Verfahrens mit mehreren, hintereinandergeschalteten Synthesestufen, in denen die Schärfe der Reaktionsbedingungen, gemessen an der Reaktionstemperatur und/oder der Konzentration an Kohlenmonoxid im Synthesegas von der ersten bis zur letzten Reaktionsstufe in Strömungsrichtung abnimmt, wird in der ersten von Synthesegas durchströmten Reaktionsstufe ein erster Katalysator mit geringer Aktivität, aber hoher Langzeitstabilität und in der letzten von Synthesegas durchströmten Reaktionsstufe ein zweiter Katalysator mit hoher Aktivität, aber geringer Langzeitstabilität eingesetzt.
