中文摘要： 新疆煤资源储量丰富、品种性能齐全，为煤基活性炭开发提供优势资源。而微波作为高效、快速、节能、操控性好的加热技术逐渐应用于炭材料领域。针对微波法定向制备新疆煤基活性炭及对有机污染物控制研究未见报道。项目拟以新疆典型煤样为研究对象，对新疆煤基活性炭的微波法定向制备过程进行研究，明确微波炭化及活化过程各因素对炭表面结构形成的影响程度，阐明微波法制备活性炭表面结构的形成规律。通过将结构特性相异的活性炭对多环芳烃污染物进行吸附研究，探讨炭表面结构与多环芳烃的吸附性能间的定量关系，进而阐明微波加热对煤基活性炭吸附多环芳烃的制-构-效关系。进一步揭示微波法定向制备对活性炭的表面结构形成规律及其对多环芳烃的吸附调控机制；项目的研究能够开发专用多环芳烃的活性炭吸附剂，并建立节能、降耗的炭质材料微波定向制备方法。同时，项目的实施能够为利用区域优势资源来解决区域环境问题具有重要的科学理论意义和实际应用价值。

英文摘要： Coal resources in Xinjiang is very rich, and its varieties and performance are verity， Which is advantageous resources for development of coal-based activated carbon. In addition, microwave are an efficient, fast, energy saving and good handling heating technologies are applied to prepare carbon materials field. However, in view of reparation of Xinjiang coal-based activated carbon by microwave method research have not been reported. Typical coal samples in Xinjiang as object of study in the project, directional preparation process of Xinjiang coal-based activated carbon using microwave method will been investigated and the process factors of carbonization and activation by microwave method for influencing the formation of surface structure the carbon will been understand, so that surface structure formation law of the activated carbon will been clarified. Through studying different structural characteristics of activated carbon prepared for adsorption of polycyclic aromatic hydrocarbons (PAHs) pollutants, the quantitative relationship of the adsorption between the surface structure of carbons and their adsorption properties on PAHs will been revealed, and the effect degree of surface structure of coal-based activated carbon on adsorption of typical PAHs was obtained. Preparation of activated carbon using m
