Für die nichtoxidative Ethandehydrierung zu Ethen wurden Katalysatoren mit isolierten Co2+‐Spezies in den 6MR‐ (Co2+‐Z2) und 8MR‐Fenstern ([Co(OH)]+‐Z) eines SSZ‐13‐Zeolithen hergestellt. Die Co2+‐Z2‐Spezies zeigten im Vergleich zu den [Co(OH)]+‐Spezies eine unerwartet hohe Ethenbildungsgeschwindikeit.

Asymptotic Properties for a General Class of Szász–Mirakjan–Durrmeyer Operators
ABSTRACT In this paper, we introduce a general family of Szász–Mirakjan–Durrmeyer type operators depending on an integer parameter j∈ℤ$$ j\in \mathbb{Z} $$. They can be viewed as a generalization of the Szász–Mirakjan–Durrmeyer operators, Phillips operators, and corresponding Kantorovich modifications of higher order.
