On August 26, the results of the 2024 Shanghai Science and Technology Awards were officially announced. The project titled “Research and Industrial Application of Key Technologies for Producing Millions of Tons of Mixed Xylene from Complex Feedstocks”, led by the Sinopec Shanghai Research Institute and carried out in collaboration with Tianjin Petrochemical, Hainan Refining & Chemical, Shenghong Refining & Chemical, Ningbo Daxie Petrochemical, and other organizations, won the first prize in the 2024 Shanghai Science and Technology Progress Award! This project overcomes the challenge of efficient conversion of macromolecules by developing crystal-face-oriented nanodisk-clustered molecular sieve materials and highly synergistic metal/molecular sieve bifunctional catalysts for aromatic hydrocarbon conversion. Innovative technologies for the multi-stage, precise conversion of complex raw materials have been developed, significantly improving the suitability for such complex and low-quality materials. It integrated and innovated the reaction-separation process flow with large-scale reactor technology, achieving a major breakthrough in the key technologies for producing mixed xylene from complex raw materials. It built the world’s largest facility for producing mixed xylene from such complex raw materials at that time, and its technology was licensed for use in more than 10 large-scale industrial plants, providing important technical support for the adjustment of China’s petrochemical industry structure and its sustainable development.
