The School of Chemical Engineering of Sichuan University has outstanding advantages in phosphorus chemical industry, phosphorus resource chemistry and clean processing of phosphate rock. After more than ten years of development, it has become the largest basic research and engineering development center for comprehensive utilization of phosphorus resources in China, with international influence.
The research center of comprehensive utilization and clean processing engineering of phosphorus resources undertaken by the School of Chemical Engineering of Sichuan University was approved by the Ministry of Education in 2006. Relying on the scientific research and discipline advantages of School of Chemical Engineering, Sichuan University, the center will establish an interdisciplinary high-level research platform and become the largest training base for phosphorus chemistry and engineering talents in China. The center has the largest research and development team of phosphorus chemistry and engineering in China, and the slurry ammonium phosphate process developed by it has had a great impact on the progress and reform of phosphate fertilizer production industry in China. In recent years, breakthroughs have been made in the purification of wet-process phosphoric acid and the large-scale production of ammonium phosphate. Six sets of large-scale ammonium phosphate plants with 200,000-300,000 tons have been built continuously, which has made outstanding contributions to the upgrading of several major phosphate fertilizer enterprises in China and the structural transformation of the national phosphate fertilizer industry, and has become a landmark achievement in the field of engineering research in Industry-University-Research.

Sichuan university new energy and new material Ditan technology research institute
This center is an interdisciplinary innovation platform established on the basis of "Research Center for Characteristic Minerals and Renewable Energy (Phase II of 985 Project)", and it is an important part of "Low-carbon Technology Research Institute for New Energy and New Materials (201KLOC-0/Innovation Plan Cultivation)" of Sichuan University. The center aims at chemical cleaner production and low-carbon technology, takes CCU (carbon dioxide recycling) as the guidance and features recycling, aiming to build a world-class high-level technological innovation platform for carbon dioxide emission reduction and a theoretical research and talent training base.
The main research direction of the center
1. CCU technology for directly mineralizing CO2 from industrial solid waste.
In view of the urgent demand for CO2 emission reduction technology in China's sustainable development and the high cost of the existing technology in the world, the technological innovation route of "treating waste with waste" and recycling CO2 is put forward, and CO2 emission reduction is completed through chemical clean production process, while environmental, resource and economic benefits are improved.
This direction is funded by the National Science and Technology Support Program, and cooperates with China Petrochemical and Wengfu Group. The project "Key Technology Research and Engineering Demonstration of Phosphogypsum Mineralized with Low Concentration Tail Gas CO2 Co-production of Sulfur-based Compound Fertilizer" has entered the field model test.
2. CCU technology of CO2 mineralization by natural minerals.
There are many minerals that can be used as natural mineralizers of CO2 in the natural range available to human beings. It is proposed that CO2 reacts with water-insoluble potash ore in catalyst solution to mineralize into solid carbonate with stable properties, and CCU technology innovation is proposed to prepare high value-added chemical products such as potash fertilizer, so that CO2 mineralization can reduce emissions in profitable production process.
This direction is funded by the National Science and Technology Support Program and cooperates with Wengfu Group and Yanchang Group. The research topic of "Key Technology Research and Pilot Test of Co-production of Potash with Potassium Feldspar Mineralized CO2" has obtained many patent achievements and has entered the pilot development.

Multiphase flow is a common way of material and energy conversion. Optimizing multiphase structure and conversion path and improving conversion efficiency are the source technologies to save resources and energy and reduce the discharge of "three wastes". Therefore, the phase transfer principle of thermodynamic potential difference control is put forward, and the emission reduction of "three wastes" logistics with small temperature difference, small concentration difference and small velocity difference is realized through phase transfer.
