Data evaluation of trace elements determined in Nigerian

High segregation of coal fly ash was observed while metallurgical coal grouped together with high-ranking coals of Okaba Enugu and Obi (Lafia) Further work revealed some of these coals as having high gross calorific value (7908 kcal kg(-1) for Enugu coal 7200 kcal kg(-1) for Okaba) and low sulphur thereby making them efficient fuel materials

coal samples The volatile matter of Lafia-Obi coal is close to that of the foreign coals while a large difference exists between Chikila coal and the foreign ones It was observed elsewhere that the Lafia-Obi coal is higher in maturity than the Chikila coal [17] and volatile matter is known to decrease with increase in rank [18 19]

Based on the maceral compositions and the Rock-Eval pyrolysis results the Lafia-Obi coals are within gas generating interval and could be a source rock in this area The Lafia-Obi coal can be of utility for the iron and steel industries if blended with high rank coal for combustion

Lafia-Obi/Foreign coals blends possess lower ash and better rheological properties compared to Chikila/Foreign coal composites which have high ash and poor rheological properties These together suggest that amongst the two Nigerian coals Lafia-Obi is superior for blending with the foreign ones in metallurgical coke production

By Chuwang Dungs Lafia The Nasarawa State governor Abdullahi Sule on Friday said his administration has set a target of generating 100 mega watts coal powered electric generation plant in the state The governor who stated this at the foundation laying ceremony of 2 kilometers solar powered street lights at Obi the headquarters of Obi Local Governments

Nevertheless the ash content of American coal Lafia-Obi and Chikila coals are relatively lower than the ash content on dry basis of the pulverised coal used in this study Similarly the low ash content is an improvement on the coking quality low ash content is an essential requirement for coke making coals
