焦炭显微结构及矿物质存在下反应性变化规律探讨

分析了焦炭显微结构及其对焦炭反应性的基本影响,探讨了矿物质的存在对焦炭显微结构的影响机理及催化作用特征。焦炭光学显微结构对焦炭反应性影响顺序为各向同性、类丝炭和破片>细粒镶嵌>粗粒镶嵌>流动型片状结构。当有矿物质存在时,其顺序恰好相反。 It analyzed the microstructure composition of coke and the basal influence to CRI,discussed the influencing mechanism of minerals to the microstructure composition of coke and the characteristics of minerals catalysis.The influence of microstructure composition of the coke to CRI is I、FR,Mf,Mc,FD、If in sequence.The existence of minerals make the influence sequence in opposition
