Abstract:

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.

Key words: gas-liquid mixing, fixed-bed hydrogenation, multiphase reaction, mass transfer, process intensification

摘要：

炼油工业作为国民经济的支柱，在创造大量财富的同时，往往存在高能耗、高物耗和高污染的问题。固定床加氢技术是重要清洁炼油技术，在油品质量升级、产品结构调整、原油资源高效利用、生产过程清洁化进程中发挥了重要的作用。提高固定床加氢效率有助于充分利用石油资源、生产清洁燃料和实现生产过程的节能降耗。本文从固定床反应器滴流床加氢和液相加氢过程的氢油两相物料混合特性出发，综述了通过开发新型混氢设备和加氢工艺，强化气液混合过程，提高固定床多相催化加氢效率的应用进展，并提出固定床加氢反应过程气液混合强化技术发展趋势，为炼油化工生产过程提质增效、节能降碳新技术的开发提供参考。
