Autor: Liu Zhifei, Cao Daiyong, Chen Gaojian, Chen Qingtong, Bi Zhongwei

Publikováno v: Frontiers in Earth Science, Vol 11 (2023)

In order to explore the graphitization characteristic differences between vitrinite and inertinite in coal, this study conducted high-temperature thermal simulation experiments (at five temperature points: 1800°C, 2100°C, 2400°C, 2700°C, and 3000

Factors affecting graphitization of coal and the experimental validation

Autor: Wang Lu, Dong Yeji, Zhang He, Cao Daiyong

Publikováno v: 矿业科学学报, Vol 3, Iss 1, Pp 9-19 (2018)

Coal gradually changes into graphite accompanied by the process of chemical constituents progressively simplifying and structure ordering, which shows the characteristics of periodic and differences.This paper summarizes the exterior conditions (temp
