Abstract
The coal gasification process in this study aims to increase the quality of low rank coal from lignite type to coal with semi- anthracite and anthracite grades with higher fixed carbon values. The gasification process is carried out at temperatures between 700 and 900 'C. In the initial stages the aim of the work is to study the relationship between gasification temperature and the mass of coal and the time for gasification process. Proximate and altimate analyzes were carried out to determine the characteristies of the raw materials used and the coal char produced from combustion. The results of the analysis are nsed to ealeulate the fuel ratio as the parameter to determine the grade of coal. In addition, a SEM-spot EDS analysis was carried out on the gasified coal solids to ensure the fixed carbon content produced from the above process. The results showed that gasification process can raise the grade of low rank coal into char products with semi-anthracite to anthracite grades with fuel ratio reached 1084. Results from product analysis of the LRC coal gasification using SEM-Sport EDS showed that the atomic percent of element C was very high, reaching 98.58%, corresponding to mass percent of 90.74%, with remaining inorganie elements less than 15% (as Al, K, Si and S).
