Abstract: The hydrogenation catalyst developed by SINOPEC Research Institute of Petroleum Processing meets the needs of full hydrogenation refinery companies. At the same time, based on the requirements of national and industrial environmental protection regulations, the concept of a green supply chain for the full life cycle of hydrogenation catalysts has been proposed. Technology development has been carried out, such as green production of carrier precursor and hydrogenation catalysts, e-Trust(ex-situ Truly sulfiding technology for hydrotreating catalyst), off-site regeneration,and cascade utilization of spent catalysts. Among these technologies, green production of carrier precursor and hydrogenation catalysts as well as off-site regeneration have been industrialized for many years. e-Trust technology has been industrialized in 2018. The regeneration of spent residue hydrogenation and cascade utilization of spent distillate hydrogenation catalyst has been made great progress. The green supply chain technology for the full life cycle of hydrogenation catalysts can not only ensure the production of green and high-value products during the industrial application of hydrogenation catalysts, but also guarantee the use or future use of green environmental technologies in process of catalyst production, start-up and shut down of refinery plant. It can comprehensively help the efficient and environmentally-friendly use of resources and promote the green and healthy development and sustainable development of the entire oil refining industry.
