Abstract

original image

Gecrackte Cracker: Mit integrierter Laser- und Elektronenmikroskopie wurden einzelne Teilchen eines Erdöl-Crack-Katalysators (siehe Bild) untersucht, die nach einem industriell relevanten Prozess desaktiviert worden waren. Die Verknüpfung fluoreszenzmikroskopisch beobachteter Veränderungen der Brønsted-Acidität mit elektronenmikroskopisch beobachteten Strukturänderungen der Zeolith- und Matrix-Komponenten ergab neue Einblicke.
