Cover Picture: Upgrading Pyrolysis Oil over Ni/HZSM-5 by Cascade Reactions (Angew. Chem. Int. Ed. 24/2012)
An active, selective, and stable catalyst (Ni in zeolite HZSM-5) was developed to convert a wide variety of C-O and C=O bonds in n-hexane-extracted pyrolysis oil into hydrocarbons through a cascade of hydrogenation, hydrolysis, dehydration, and dehydroaromatization reactions. In their Communication on page 5935 ff., J. Lercher and C. Zhao show that C5–C9 gasoline-range hydrocarbons are produced quantitatively from extracted crude bio-oil using Ni/HZSM-5 catalysts under mild conditions in water.
