Abstract

Es wird ein Verfahren zur Herstellung von Formaldehyd durch nicht-oxidative Dehydrierung von Methanol in einem Reaktor unter Verwendung eines fluiden Katalysators beschrieben, bei dem die Produktgase nach dem Reaktor in einem Kühler in Kontakt mit einer Schmelze gebracht werden, welche Verunreinigungen und Katalysatorreste aufnimmt. Zur Durchführung des Verfahrens kann auch ein Reaktor dienen, der als Blasensäulen- oder Gegenstromfallfilmreaktor ausgeführt ist und eine Katalysatorschmelze enthält. Der Kühler ist vorzugsweise als Fallfilmkühler ausgebildet.
