Particles collected during in situ gasification of Texas lignite experiments were analyzed for chemical elements. Results obtained by energy dispersive x-ray analysis revealed that the dominating elements in both particles and lignite are Si, S, Al, Fe, and Ca. The concentration of these elements depends on the selected region and varies within the particle size range. Semi-quantitative analysis revealed the same results. This paper presents the scanning electron microscopy (SEM) micrograph and energy dispersive x-ray analysis (EDXA) for particles and Rockdale lignite.
