摘要:

通过引入分形理论研究焦炭微观气孔结构的内在规律和特征,揭示焦炭的反应性与焦炭气孔分形维数变化幅度的关系。采用压汞法对反应前后焦炭的孔结构进行测定,研究CO2浸蚀引起的焦炭微观气孔结构变化,提供了研究焦炭熔损反应的新方法。

Abstract:

This paper studies the intrinsic law and characteristics of coke micro pore structure by introducing fractal theory so as to demonstrate the correlation between the coke CRI and fractal dimension variation.The coke pore structures before and after reaction are measured by adopting mercury penetration method so that the coke micro pore structure change due to CO2 erosion can be analyzed and a new solution to the coke melting is given.
