Abstract: RL-2 catalyst was applied in the first reactor of No.1 high pressure hydrotreating unit of PetroChina Karamay Petrochemical Co., Ltd. in Aug. 2018 during plant turnaround. After sulfidation and initial activity stabilization, the catalyst was transferred to normal operation. At the initial stage of application, on the premise of ensuring the product quality, RL-2 catalyst entered the stable period of high catalytic activity fast and showed a good adaptability for different feedstock. Nearly one year operation indicated that RL-2 catalyst had good activity stability. The oil yield under each feedstock scheme remained at a high level.

Key words: RL-2 catalyst, lubricating oil, high pressure hydrotreating
