Abstract

Abstract:

Hydrogenation technology is an indispensable main means of producing clean oil products and improving product quality, which is the core of refining and chemical integration. Despite decades of development, hydrogenation technology has made considerable progress, but there are still several problems such as high investment and operating costs, high energy consumption, etc, which are unable to meet the requirements of petrochemical companies for sustainable development. The progress of low-investment and low-energy hydrogenation technology in China is briefly described, such as hydrocracking catalyst grading technology for strengthening the catalytic reaction process, light cycle oil hydroconversion technology with enhanced reaction conditions, low energy consumption and low investment SHEER technology to strengthen the heat transfer process, and liquid phase circulation hydrogenation technology for enhancing mass transfer process. It is proposed that future hydrogenation technology will play an increasingly important role as a hub for refining and chemical integration. It will achieve a coordinated spiral upgrade through coupling and perfecting process intensification technology. The complex system reaction behavior of the upgraded hydrogenation technology is closer to the intrinsic reaction state. The hydrogenation technology will achieve a high degree of atomic economy, which is more in line with the future needs of the green development of human society.

Key words: process intensification, reaction engineering, catalyst activation, hydrogenation, integration

摘要：

加氢技术是生产清洁油品、提高产品品质所不可或缺的主要手段，是炼油化工一体化的核心。虽然几十年的发展获得了长足的进步，但存在投资和操作成本高、能耗高等问题，不符合石油化工企业实现可持续发展要求。本文简述了我国在低投资、低能耗加氢技术方面的进步，分别介绍了强化催化反应过程的加氢裂化催化剂级配技术，强化反应条件的催化柴油加氢转化技术，强化传热过程的低能耗、低投资SHEER技术以及强化传质过程的液相循环加氢技术。提出未来加氢技术作为炼化一体化的枢纽，将扮演越来越重要的角色，其通过耦合完善的过程强化技术将实现协同螺旋式升级，升级后的加氢技术的复杂体系反应行为更接近本征反应状态，加氢技术将实现高度的原子经济性，更符合未来人类社会绿色发展的需求。
