Parameter for judging reactivity of coal and coke

HE Hongzhou, LUO Zhongyang, CEN Kefa

Frontiers in Energy 2008, Volume 2, Issue 3,   Pages 354-358 doi: 10.1007/s11708-008-0052-z

Abstract: To eliminate the judgment error of char reactivity arising from different carbon content of samples,The reactivity of different kinds of coal, the reactivity of the same coal type with different lithotype, and the reactivity of the char with different carbon conversion rates were checked by using the specificspecific maximum weight loss rate can be used as a commonality parameter to evaluate and distinguish the reactivity
