ABSTRACT: The 300kg coke sample received from Ajaokuta Steel Plant was subjected to proximate
analysis and pilot scale size distribution test. The proximate analysis showed that the coke
contains 0.38%, 13.45%, 2.72% and 0.14% of moisture, ash, volatile matter and sulphur
respectively; while size distribution test gave micum 10 and micum 40 of 3.62% and 89.67%
respectively. Therefore, the coke satisfies the blast furnace requirements for moisture,
sulphur and micum strength. However, its ash and volatile contents exceed the specified
limits except for Indian standard practice.
