The U.S. Department of Energy, Pittsburgh Energy Research Center, carried out two typical gasification tests of Illinois No. 6 coal in the SYNTHANE process primarily to determine the paths of trace elements. Spark source mass spectrometry quantified by computer-assisted photoplate analysis identified 65 trace elements. Most of the trace elements in the feed coal were recovered in the char; these ranged from a low of 0.1 ppm of mercury to a high of 19 ppm of nickel. The major elements, carbon, hydrogen, nitrogen, oxygen, and sulfur were determined by standard ASTM procedures; minor elements, iron, aluminum, silicon, sodium, calcium, potassium, magnesium, and chlorine were determined by gravimetric or atomic adsorption techniques. Average over-all recoveries of Vertical Bar3: 95Vertical Bar3< were obtained for the major elements, which are found primarily in the product gas. Recoveries of Vertical Bar3: 87Vertical Bar3< were attained for the minor elements, found principally in the char, except for chlorine which was principally in the condensate water. The distribution and quantities of arsenic, beryllium, cadmium, lead, mercury, nickel, selenium, and vanadium are discussed.
