As the pillar of national economy,oil refining industry often has the problems of high energy consumption,high material consumption and high pollution while creating a lot of wealth.Fixed-bed hydrogenation technology is an important clean oil refining technology,which plays an important role in the upgrading of oil quality,the adjustment of product structure,the efficient utilization of crude oil resources and the clean production process.Improving the efficiency of fixed-bed hydrogenation is helpful to make full use of petroleum resources,produce clean fuel and realize energy saving and consumption reduction in production process.Based on the mixing characteristics of hydrogen and oil two-phase materials in the trickle-bed hydrogenation and liquid-phase hydrogenation processes of fixed-bed reactor,this paper reviewed the application progress of gas-liquid mixing intensification which improved the efficiency of fixed-bed multiphase catalytic hydrogenation by developing new hydrogen mixing equipment and hydrogenation process,and proposed the development trend of gas-liquid mixing intensification technology in fixed-bed hydrogenation process.It provides reference for the development of new technologies for improving quality and efficiency,saving energy and reducing carbon in refining and chemical production process.
