Team Leader Professor MA Liping(one of the team leaders): Director of the Department of Renewable Resources Science and Technology, Doctoral Supervisor, Doctor of Sichuan University in Chemical Engineering (2002), visiting scholar to the Department of Chemical Engineering of Michigan University (February,2006-February,2007 ), one of the scholars presiding over National 863 Program and National Natural Science Foundation of China
Research Field: Solid Waste Resources Comprehensive Utilization
Solid Waste Resources Recycling and Harmless Disposal Innovation Team: Focusing on regional economic development and the requirements of national industrious policies, several research fields have been established including Non-ferrous Metallurgical Waste Recycling, Solid Waste Harmless Disposal, Application of Microwave Energy in Renewable resources Utilization, and Environmental Materials, and the assessment system has also been built for Solid Waste Comprehensive Utilization and Recycling.
On the resources recycling of industrious solid waste of gypsum, comprehensive and systematic integration technologies have been developed for utilizing the phosphogypsum and desulfurization gypsum generated in the production processes in the phosphorous and coal chemical industries, coal and electricity industries that are dominant in western China. Aiming at producing sulphuric acid and cement, absorbing CO2, recycling calcium resources, developing fine CaO and CaCO3 products, in-depth and fundamental researches have been conducted on the recycling of sulphur and calcium resources to propose systematic theories, and form integration processes and advance equipment.
On the new technologies of coal-chemical resources recycling, the theory of Transcritical Gasification has been innovatively proposed and applied to the catalytic gasification of coal. Specifically, by virtue of the unique physical and chemical properties of high-pressure hot water, the gasification, water-gas conversion and methanation of coal and high-pressure water are conducted in one reactor with catalyst at high pressure, medium and low temperature(500℃-700℃),and coal-based natural gas will then be synthesized directly. Many patents have been industrialized in the USA and Canada, and a dozen major technologies applied in industries.
On the comprehensive utilization of mining and metallurgical waste, tailings that contain valuable metals and blast furnace slag generated in metallurgical industries have been recycled. The mechanism of metal recycling and the systematic theories of comprehensive separation have been analyzed and improved, thus providing key technologies for industrious application. The metal resources including Cu and Fe in Cooper-smelting slag have also been recycled. The researches on the technology of the synthesis of ceramic-matrix composites from metallurgical solid waste, and on the light and environment-friendly building materials have been conducted, by which the products that meet corresponding national standards have been yielded.
