Abstract
The fluidized bed reactor, as an efficient and flexible chemical engineering equipment, holds significant application value in the petrochemical industry. With the increasing scarcity of petroleum resources and the continuously rising environmental protection requirements, the development of high-performance fluidized bed reactors has become a focal point of the industry. This study aims to investigate the application characteristics and performance optimization strategies of fluidized bed reactors in petrochemical processes. By integrating theoretical analysis with experimental research, the impact of various operating parameters on reaction efficiency was systematically examined. It was found that optimizing gas-solid contact methods, adjusting catalyst distribution patterns, and improving internal structure design can significantly enhance reaction efficiency and selectivity. Particularly in key processes such as heavy oil hydrocracking and catalytic reforming, the new-type fluidized bed reactors demonstrated excellent mass and heat transfer properties along with anti-coking capabilities. An innovative multi-scale simulation-based model for predicting internal flow characteristics of the reactor was proposed, providing a theoretical basis for precise control. Additionally, addressing issues in industrial scale-up, a comprehensive engineering amplification methodology system was established to ensure the smooth transition of laboratory achievements into practical productivity. The research outcomes not only offer technical support for enhancing the operational level of existing facilities but also lay a solid foundation for the development of next-generation energy-efficient fluidized bed reactors.
