Gray-King Assay Characterisation of Nigerian Enugu and Polish Bellview Coals for Co-carbonisation

A.O. Adeleke, R.S. Makan and S.A. Ibitoye

Abstract: The Nigerian Enugu and Polish Bellview coals were subjected to proximate analysis and Gray-King coke assay type tests. Proximate analysis gave the ash content as 7.57 and 5.56%, the volatile content as 51.76 and 31.06%, respectively for Enugu and Bellview coals. For the Gray-King coke type assay test, the coke types of B and G, the percentage coke yield of 71.70 and 80.40% and percentage tar yield of 23.30 and 11.40%, respectively, were determined for Enugu and Bellview coals. The coke type, the ash content and percentage coke yield confirms Bellview coal as a medium coking coal, suitable for cokemaking but with a volatile content that exceeds the upper limit of 30.3% for cokemaking at Ajaokuta and Enugu coal as a high volatile non-caking coal. However, the higher yield of tar from Enugu coal may be an advantage in its use as a binder in producing formed coke.
