摘要

A process for determination of Coal Char Reactivity Index (CCRI) arid Coal Char Strength After Reduction (CCSR) directed to favour deciding on the suitability of coal for processes especially the Corex process, smelting reduction iron making process and Finex process. Importantly, the above process would favour simulating and giving an understanding of the condition such as reactivity of coal char near tuyeres, strength and permeability of coal char. Thus, the invention is directed to the development of much desired test procedure which can simulate the coal char reactivity and its strength after reaction near tuyeres of Corex and Finex processes for effective and proper utilization of such processes where melter-gasifier function is involved.
