采用气体活化法制备活性焦，通过控制温度和烧失率来控制孔结构生成过程，制取具有特定孔结构的活性焦。采用N2吸附法对样品的孔结构进行表征，并在固定床实验系统上对不同样品的脱硫性能进行测试研究。研究发现：活性焦制备过程中，低温活化有利于活性焦微孔结构的形成和脱硫性能的提高，微孔是活性焦脱硫反应发生的主要场所，中孔和大孔作为分子扩散通道并具有存储H2SO4的作用，微孔比表面积可以作为判断活性焦脱硫性能的关键指标。

Steam activation was used to prepare activated coke (AC). The pore structure generation process was controlled through the control of temperature and burning loss rate, and thus a special pore structure activated coke was prepared. The pore structure of the samples was characterized by N2 adsorption, and SO2 adsorption properties of different ACs were studied on the fixed bed system. In the preparation of AC, low temperature activation contributed to formation of micropore structure and improved desulfurization performance. Micropores were the main sites of active coke desulfurization reaction. Mesopores and macro-porous were the diffusion channels for molecules and store H2SO4. Microporous surface area could be used as a key indicator to evaluate desulfurization performance of active coke.
