Study on hydrodenitrogenation performance of Shenli coal liquefied middle oil on NiMo/Al_2O_3,NiMo/MCM-48 and NiMo/Betonite

The evaluation of hydrodesulfurization (HDN) and hydrodenitrogenation (HDS) properties of Shenli coal liquefied middle oil on NiMo/Al2O3,NiMo/MCM-48 and NiMo/Betonite catalysts is carried out at 340℃ under 5.0 MPa of hydrogen pressure.Results show that the activities of catalysts on the three types of supports are different.The HDN activities are higher than that of HDS for all catalysts.The type of support significangly affects the activities of HDN and HDS.The catalytic activity of hydrodeoxygenation (HDO) follows the order of NiMo/BetoniteNiMo/Al2O3NiMo/MCM-48.The catalytic activity of hydrodearomatization (HDA) follows the order of NiMo/Al2O3NiMo/MCM-48NiMo/Betonite.
