Abstract
Catalytic distillation technology, as an innovative chemical separation method, demonstrates unique advantages in olefin separation. With the increasing demand for high-purity olefins in the petrochemical industry, traditional separation methods face issues such as high energy consumption and low efficiency, necessitating the development of more efficient separation processes. This study investigates the application potential and optimization strategies of catalytic distillation in olefin separation by integrating experimental research with theoretical analysis, systematically examining the impact of different catalyst types, reaction conditions, and operating parameters on separation performance. It was found that the use of novel zeolite catalysts significantly enhances separation selectivity while reducing energy consumption. By optimizing the tower structure design and operating parameters, higher product yield and purity were achieved. Additionally, a mathematical model was established to predict separation performance under various operating conditions, and its accuracy was verified through experiments. This research not only provides theoretical foundations and technical support for industrial applications but also proposes an online optimization scheme based on intelligent control systems, effectively addressing bottlenecks in traditional processes and offering new insights for achieving green chemical production, thereby possessing significant academic value and practical application prospects.
