摘要
将分形理论的概念应用到煤焦气化研究中 .煤焦气化过程孔结构参数间的变化规律符合一定的分形关系 ,气化速率越大 ,分形维数也越大 ,但是分形理论并不适用于所有煤焦气化过程研究 ,只有那些孔容积绝大部分由中小孔构成的煤焦才符合分形规律 .
Fractal concepts was introduced in the study of char gasification.The changes of pore surface area and pore volume of char during gasification could be described in accordance with a fractal rule.The quicker the char gasified,the higher the fractal dimension was.However,fractal rule could only be used to describle the coal char gasification that the char pore volume was made up of micropore and mesopore.
