Abstract

A total of six coal samples labeled (AGB, EHA, INY, LAF, OHN, and SHJ) were collected within our map area and sent to the laboratory for standard proximate analyses for ranking of the coals based on ASTM D388 – 05 standard classifications of coal ranks. The coal parameters obtained from the laboratory are moisture content (Mc), volatile matter (Vm), fixed carbon (Fc), ash content (Ac), sulphur content (Sc), mineral content (Mc), heating values (Hv), calorific values (Cv), fuel ratio (Fr), and free swell index (Fsi). The values of these parameters show that two (LAF, SHJ) of the six coal samples are of high ranking and are of bituminous grade while the other four (AGB, EHA, INY, and OHN) coal samples are of lower rank and are of sub-bituminous grade. The bituminous coals in Lafia-Obi and Shankodi-Jangwa areas are of large quantities and are used for production of coke used in blast furnaces for production of steel. It can also be used for domestic heating especially where anthracite is not available. The subbituminous coals located in Agbogugu, Eha-Etiti, Inyi, and Ohandiagu are of very large quantity and are used in generating steam for the production of electricity in power plants. In addition, sub-bituminous coals can be liquefied and converted to petroleum and gas. However, the use of sub-bituminous coal can lead to hazardous emissions into the environment especially harmful smoke, soot, sulphur oxides, nitrogen oxides and mercury. The low sulphur content is attributed to shallow marine depositional environment, which restricted sea water incursion during peat formation in the Coalification process.
