The hydrodenitrogenation performance of hydrotreating catalyst RN-1 was investigated in order to prepare high quality lube base oil. The experiments were conducted on a 20 mL fixed bed hydrotreating unit with 150BS and 150SN oil as feeds. The effects of temperature, hydrogen partial pressure and space velocity on catalyst performance were investigated respectively. The results show that the hydrodenitrogenation rate of 150BS is 99.1% under the condition of a temperature 410 ℃, a pressure of 14 MPa, a WHSV of 1.00 h -1 , a H 2/Hydrocarbon molar ratio of 500 and the hydrodenitrogenation rate of 150SN oil is 99.4% under the condition of a temperature 380 ℃, a pressure of 13 MPa, a WHSV of 1.00 h -1 , a H 2/Hydrocarbon molar ratio of 500. RN-1 catalyst has a premium hydrodenitrogenation performance. It can be used in hydrotreating of 150BS and 150SN oil.
