利用垃圾微波裂解固体产物制作活性炭的研究 摘 要950℃，活化时间为5h，蒸汽流量0.5L/min470 mg/g，亚甲蓝吸附值为47mg/g，比表面积值为830m2/g。 关键词： ABSTRACT Will produce a lot of garbage microwave pyrolysis of solid waste, in order to prevent secondary pollution, the need for solid resource utilization. This article first obtained by screening of a higher carbon content of solid powder, pickled, flotation to further improve the carbon content, preparation of activated carbon required to achieve the requirements of the carbon content, further steam activation, and finally be activated Experiment, use the carbon content of various parts of diffraction X fluorescence was measured by the activated carbon to be iodine adsorption value, methylene blue adsorption value and specific surface area measured by the test findings were as follows: The purpose of screen 200 under the powder, by pickling and preparation of activated carbon can be achieved after the flotation required carbon content of the pickling process more suitable for the introduction of 30% hydrochloric acid pickling temperature is 90 ℃, time of 20min; steam activation temperature of 950 ℃, activation time of 5h, the steam flow 0.5L/min. Preparation of the final determination of iodine adsorption value of the activated carbon 470 mg / g, methylene blue adsorption value of 47mg / g, specific surface area value of 830m2 / g. Key words: Solid Waste, Activated Carbon, Carbon content, Steam activation 目 录 摘 要 1 ABSTRACT II 1 绪 论 1 1.1 研究的目的和意义 1 1.1.1 研究的目的 1 1.1.2 研究的意义 1 1.2国内外研究及现状 2 1.3 活性炭及其表征 3 1.3.1 活性炭 3 1.3.2活性炭的种类 3 1.3.3 活性炭的吸附原理 4 1.3.4 活性炭的表征 5 2 实验部分 6 2.1 实验药品与仪器 6 2.2 工艺技术路线 8 2.2.1 工艺路线图 8 2.2.2 活性炭制备工艺 9 2.2.2.1 实验准备 9 2.2.2.2 多级筛选 9 2.2.2.3 酸洗水洗 9 2.2.2.4 浮选 10 2.2.2.5 水蒸气活化 10 2.2.3 检测方法 12 2.2.4关键技术解决 12 3 实验数据及分析 14 3.1 多级筛选 14 3.2 酸洗水洗 15 3.3 影响气体活化的因素 16 3.3.1 活化剂对活化过程的影响 16 3.3.2 活化温度的影响 17 3.3.3 活化时间的影响 18 3.3.4 水蒸气流量的影响 19 3.4 小结 19 4 结 论 21 4.1 结论 21 4.2 本课题的创新之处 21 参考文献 22 附 录 23 附录1：实验中的原始数据 23 致 谢 24 1 绪 论（500～3000 m2/g）1.1 研究的目的和意
