Abstract：Since the project was officially launched， the team conduct a large number of studies， combine with expert advice， thus further clarify the research focus， adjust and improve the scheme. As the project goes， constantly and timely adjusting experimental scheme； refine the research process. After the first year of the project construction， improve the research content， form clear research objectives and laid a solid foundation for the project to conduct smoothly and orderly.（1）The team completes the basic indicator analysis of typical low-quality coal， preliminarily discover how the principal forming-ash minerals/sulfur/moisture of the typical low-quality coal exist and clarify surface oxygen functional groups and pore structure.（2）The team establishes a lignite-dewatering system under pressure and high temperature， lignite-upgrading unit through hot water，CO2 supercritical extractor， and lignite-drying in hot flue gas （nitrogen） lab facilities. Taiyuan University of Technology establishes lignite-upgrading relapse experimental platform. we build calculating simulation platform of lignite dehydration based on high performance servers like dawn 5000A， IBMPOWER755、DELL、BAODE etc. and calculation software like GAUSSIAN09、ADF、MS5.5、VASP，SIESTA.（3）The team establishes a platform for testing electromagnetic characteristics. Through its wholly-component separation， Soxhlet extraction， XPS， GC / MS and other methods， we discover the surface structure and distribution of organic sulfur of the coking coal. Obtain the complex permittivity of coking coal samples from Xinyu at different frequencies using electromagnetic characteristics-testing system. Preliminarily discover optimal microwave band for desulfurization， research theoretically the structure and properties of benzothiophene and four- six two methylbenzothiophene using the DMol3 module in Materials Studio 6.0 software. In summary， from January 1， 2012 to October 31， 2012， 83 people participate the project， 1 monograph and 51 papers including 18 SCI and 11 EI and 1are published. 10 important academic conference Plenary Lectures are given. The team apply for 15 invention patents， two are authorized， and train 9 doctors and 21 masters in total.
