Abstract

Hydrodeoxygenation (HDO) of lignocellulose-derived oxygenates to diesel or jet fuel range C8–C18 alkanes usually requires harsh reaction conditions. A fairly mild (160 °C, 4 MPa H2) one-pot catalytic HDO system based on Ru/HAP combined with the HZSM-5 catalyst was developed, and a series of diesel or jet fuel range alkanes (C8–C18), including straight, branched, and cyclic alkanes, were obtained from nine complicated lignocellulose-derived oxygenates with a desired yield. Ru/HAP was characterized by a series of analyses, indicating that the electron donor effect of HAP led to the generation of highly dispersed electron-rich Ru, which demonstrated stronger hydrogen activation and hydrogenolysis ability.
