Catalytic hydrodeoxygenation (HDO) is one of the most effective methods to upgrade the oxygen-containing compounds derived from coal tar to valuable hydrocarbons.Herein,an efficient bimetallic catalyst Pt1Ni4/MgO was prepared and applied in the HDO of dibenzofuran (DBF).High yield (95％) of the desired product bicyclohexane (BCH) was achieved at 240 ℃ and 1.2 MPa of H2.Superior catalytic performance could be ascribed to the “relay catalysis” of Pt sites and Ni sites,and the reaction pathway is proposed as well.Scale-up experiment and recyclability test were also performed,which demonstrated the recyclability and promising potential application of Pt1 Ni4/MgO.
