Abstract

The widespread occurrence and availability of coal makes it the world's prime source of energy for different end use applications. Coal is commonly used for electricity production through coal combustion. However, many researchers have indicated that coal combustion is a prime contributor to emission of greenhouse gases contributing to global warming. During combustion gaseous elements such as sulfur, hydrogen, carbon and nitrogen react with oxygen to produce their respective oxides. These oxides contribute to global warming, air and water pollution as well as acid deposition. Emission of these oxides and their effect on the environment has resulted in increased interest in clean coal technologies. Clean coal technologies, such as coal gasification technology, use multiple technologies to control the emissions so as to minimize environmental effects from coal utilization. In this paper, the characteristics of Morupule coal from the south and east main sections are determined to establish its suitability for gasification. The characterization was conducted using thermal analysis (Thermogravimetric Analyzer) and an X-Ray Fluorescence (XRF). Numerical simulation was also carried out using Ansys software for species transport. The samples proved the coal to be from a high ash and sulfur content and medium volatiles bituminous parent rock, whilst species transport revealed a sufficient syngas yield per kilogram of coal for downstream processes.
