| Abstract: | The catalytic effects of minerals (oxides) on solution loss reaction of coke were investigated in detail by adding oxides to coal which produces coke or absorbing oxides on coke surface. The mineral catalysis index ( MCI ) which can be used to evaluate catalytic effects of minerals on solution loss of coke comprehensively was proposed. Using the volatility of coal in dry basis and MCI of coal as independent variables to control coke reactivity, the mathematical models of predicting coke reactivity index, coke strength of reactivity were constructed on the basis of the experimental results. |
