Effect of Total Ash Content and Coals Ash Composition on Coke Reactivity


Vitaly Gulyaev, Vadim Barsky and Natalya Gurevina

The article deals with the hypothesis of the influence of coals mineral components on coke reactivity. It has been shown that the reaction between carbon and carbon dioxide proceeds in kinetic area and its rate depends upon total ash content of coked coal. The data showing catalyst effect of coal mineral components upon their organic mass pyrolysis and consequently upon coke reactivity have been presented.
