Our country has a large import volume of crude oil.At the same time,crude oil has gradually become heavier globally.The clean conversion of heavy oil in the refining industry is crucial,especially the efficient utilization of residue.Based on the difference kinds of residue,this paper analyzes the characteristics and catalysts R&D progress of different hydrotreating technologies,such as fixed bed,fluidized bed and slurry bed.This article also summarizes the conversion process of unconverted residue from hydrogenation to high value-added chemicals,and looks forward to several future development directions of refineries,including transitioning towards green,low-carbon,and integrated refining;utilizing the advantages of hydrogenation technology combination;developing high activity and low-cost catalysts,etc.Combination processing techniques can be reasonably chosen based on the properties of feedstock and product purpose.The hydrogenation technology of residue should better play its bridging role.Namely,using inferior feed oil to provide higher quality products for downstream processes,thereby achieving efficient utilization of residue.
