Suppression of the Aromatic Cycle in Methanol-to-Olefins Reaction over ZSM-5 by Post-Synthetic Modification Using Calcium

The front cover artwork for Issue 19/2016 is provided by researchers from the Catalysis Engineering group at TU Delft (The Netherlands). The image shows that after impregnation with Ca, ZSM‐5 becomes a “super‐catalyst”, which is able to suppress formation of aromatics thus increasing selectivity to the desired propylene in MTO reaction. See the Full Paper itself at http://dx.doi.org/10.1002/cctc.201600650. “ZSM‐5 can be compared to a human who got the supernatural abilities to fight evil of MTO world—coke” This and more about the story behind the research featured on the front cover can be found in this issue's Cover Profile.
