Front Cover: Coking Reduction of Cr‐loaded Beta Zeolite during Polymer Cracking: Hydrocracking of Aromatics by Synergistic Effect of Cr6+ and Zeolitic Acid Sites (ChemCatChem 21/2023)

The Front Cover shows the effect of Cr6+ species on zeolites for coking resistance during the catalytic cracking of low-density polyethylene. The Cr6+ species can be stabilized by the silanol groups in zeolites and exhibit the dehydrogenation activity of light alkanes, which are produced a lot during the catalytic cracking of polyolefin. Moreover, aromatics, which is a coke precursor can be decomposed via hydrogenation at the zeolitic acid sites. In their Research Article, S. Kokuryo, K. Miyake and co-workers reveal that the synergetic effect of H2 generation by Cr6+ and the decomposition of the coke precursor by zeolitic acid sites resulted in the reduction of coking. More information can be found in the Research Article by S. Kokuryo, K. Miyake and co-workers.
