Reaktanten- und Produktkonzentrationen in einem Durchflußreaktor direkt zu bestimmen gelingt mit der hier vorgestellten Technik, die auf der Messung der beim Positronenzerfall von 11C gebildeten γ-Photonen beruht. Dies wird an der technisch sehr wichtigen Hydroisomerisierung von n-Hexan an einem Pt/H-Mordenit-Katalysator gezeigt. Dabei konnte unter anderem geklärt werden, welche Prozesse bei der Vorkonditionierung des Platins und bei der Katalysatordesaktivierung ablaufen.
