活性焦孔结构演变规律及对脱硫性能的影响
Activated coke pore structure evolution and its influence on desulfuration
摘要
Abstract
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.关键词
