Abstract

This study aimed to characterize the coal in terms of proximate and ultimate analyses. The analytical assessment of properties such as volatile matter, moisture, fixed carbon, and ash content are very important to know the quality of the coal. The proximate analysis results shows that the moisture content varies from 13.4 to 22.6 wt%, the fixed carbon varies from 26.7 and 38 wt%, the ash content varies from 11.9 to 25.7 wt%, the volatile matter varies from 23.8 to 36.5iwt%. The analytical results show that the Carbon content varies from 48.60 to 70.68 wt%, Oxygen content varies from 42.29 to 57.38 wt%, the hydrogen content ranges from 4.43 to 5.28 wt%, the sulphur varies from 1.35 toi3.04 wt%, the Nitrogen content varies from 1.86 to 2.34 wt%. Proximate analysis and calorific data show that Ethiopian coal is in the soft coal series (lignite to bituminous coal) and is genetically classified as humic, sapropelic and mixed coal. The present study helps to characterize the coal type and also highlights the importance of chemical parameters in characterizing the coal besides, tracing the depositional environment and also helps to the economical evolutions of the deposit.
