Preparation of high-performance activated carbon from char of biomass pyrolysis with the application in the removal of 2-nitrophenol from aqueous solution

近年来，活性炭的优点越来越为人们所熟知，它具有优良的液相和气相吸附性能，其表面又有着多种官能团。因此，活性炭不仅可作为催化剂或催化剂的载体，而且在废水处理、废气处理、产品合成等方面也获得了广泛应用。尽管如此，活性炭传统制备工艺常常对环境造成污染；另外，制备活性炭的原料多为木材、煤炭等，资源有限。在讲求环境保护、可持续发展的当下，有必要寻找新的原料及工艺。本文从三方面对活性炭开展了研究，包括生物质热解炭化学活化法制备活性炭，生物质热解炭物理-化学联合活化法制备活性炭，以及对制得的活性炭进行邻硝基苯酚的吸附应用实验。本研究创新性地使用ZnCl2-CO2及H3PO4-CO2活化体系制备得到性能优良的...In recent years, the merits of activated carbon become more and more well known. It has excellent performance in gas adsorption and liquid adsorption because there are various kinds of functional groups on its surface. Activated carbon can be used as catalyst or catalyst support, and has also been widely used in the areas of waste water treatment, waste gas adsorption, product synthesis, etc. Howe...学位：理学硕士院系专业：能源研究院_能源化学学号：3242012115213
