to sporinite in the Okaba coal (total liptinite of 7.5%, on the mineral-free basis). The liptinite distribution pattern could be attributed to changes in vegetation and freshwater conditions in the depositional environment (Ao et al. 2012). The relatively high vitrinite and low inertinite in the coal seam from Benue Trough indicates that anaerobic

1. Coal Beds Generally Have Flat Tops and Bottoms. Sure enough, when we looked at the coal in front of us, it was flat on both top and bottom. When we started looking at coal beds in photos, they always seemed to be enclosed within rock in these extremely flat layers.
Fly ash is either deposited as dry or hydraulic ash, the sulphur content of coal varies considerably with the nature and origin of the fossil deposits (Folahan, 2012) the utilization of coals for both energy production and various coal conversion processes is limited by the presence of sulphur in the coal, sourcing for the right type of coal ...

Coal is a sedimentary deposit composed predominantly of carbon that is readily combustible. Coal is black or brownish-black, and has a composition that (including inherent moisture) consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material. It is formed from plant remains that have been compacted, hardened, chemically altered, and
