Title: Coal Feed-Dependent Variation in Fly Ash Chemistry in a Single Pulverized-Combustion Unit

Abstract

Four suites of fly ash, all generated at the same power plant, were selected for the study of the distribution of rare earth elements (REE). The fly ashes represented two runs of single-seam/single-mine coals and two runs of run-of-mine coals representing several coal seams from several mines. Plots of the upper continental crust-normalized REE, other parameters derived from the normalization, and the principal components analysis of the derived REE parameters (including the sum of the lanthanides plus yttrium and the ratio of the light to heavy REE) all demonstrated that the relatively rare earth-rich Fire Clay coal-derived fly ashes have a different REE distribution, with a greater concentration of REE with a relative dominance of the heavy REE, than the other fly ashes. Particularly with the Fire Clay coal-derived fly ashes, there is a systematic partitioning of the overall amount and distribution of the REE in the passage from the mechanical fly ash collection through to the last row of the electrostatic precipitator hoppers.

Signatures of rare earth element distributions in fly ash derived from the combustion of Central Appalachian, Illinois, and Powder River basin coals

Journal Article Hower, James C. ; Groppo, John G. ; Hsu-Kim, Heileen ; ... - Fuel

We report the distribution of Rare Earth elements (REE) in coal-derived fly ashes can have distinctive patterns when fly ashes are produced from different coals within or between basins, such as the Pennsylvanian Class F fly ashes from the Illinois and Central Appalachian basins. Both the Fire Clay coal and a blend of a number of eastern Kentucky coals show strong Gd peaks and an H-type distribution in the Upper Continental Crust-corrected plots. The Fire Clay coal-derived ash has a higher heavy REE concentration than the blended coal-derived ash. The Illinois Basin-derived fly as has an overall lower REE concentrationmore »« less

Distribution of rare earth elements in fly ash derived from the combustion of Illinois Basin coals

Journal Article Hower, James C. ; Groppo, John G. ; Hsu-Kim, Heileen ; ... - Fuel

This study examined rare earth element (REE) trends for Illinois Basin coal-sourced fly ashes, with the goal of understanding the elemental composition and resource potential for various fly ash fractions. Illinois Basin coals have a high volatile C through A bituminous rank with a moderate ash content (slightly>12% ash (dry basis)), about 3% sulfur, and, in general, lower concentrations of hazardous and other trace elements than many Central Appalachian coals. Fly ash from the combustion of Illinois Basin coals tends to have a high Fe₂O₃ content owing to the amount of pyrite in the feed coals. The rare earth elementmore »« less

Effects of roasting additives and leaching parameters on the extraction of rare earth elements from coal fly ash

Journal Article Taggart, Ross K. ; Hower, James C. ; Hsu-Kim, Heileen - International Journal of Coal Geology

Coal fly ash is a promising alternative source for rare earth elements (REE), which are critical materials in many technologies. REEs are entrained in the aluminosilicate glass of the fly ash particles, hindering their ability to solubilize during acid leaching. The purpose of this research was to test the effectiveness of roasting techniques to improve extraction of REEs from fly ash, determine key parameters controlling REE extraction, and understand trade-offs in reagent use. Representative coal ash samples from major U.S. coal basins (Appalachian, Illinois, and Powder River basins) were roasted using a variety of chemical additives (Na₂O₂, NaOH, CaO, Na₂CO₃,more »« less

Selective Recovery of Rare Earth Elements from Coal Fly Ash Leachates Using Liquid Membrane Processes

Journal Article Smith, Ryan C. ; Taggart, Ross K. ; Hower, James C. ; ... - Environmental Science and Technology

Coal combustion residues and other geological waste materials have been proposed as a resource for rare earth elements (REEs, herein defined as the 14 stable lanthanides, yttrium, and scandium). The extraction of REEs from residues often generate acidified leachates that require highly selective separation methods to recover the REEs from other major soluble ions in the leachates. We studied two liquid membrane processes (liquid emulsion membranes, LEM, and supported liquid membranes, SLM) and compared them to standard solvent extraction techniques for selective recovery and concentration of REEs from a leachate of coal fly ash. All separation methods involved an organicmore »« less

A review of rare earth elements and yttrium in coal ash: Content, modes of occurrences, combustion behavior, and extraction methods

Journal Article Fu, Biao ; Hower, James C. ; Zhang, Wencai ; ... - Progress in Energy and Combustion Science

Rare earth elements and yttrium (REY) have attracted considerable attention over the last decade because of their vital roles in clean energy, consumer product, national defense and security applications, among other uses. Due to the retention of REY during coal burning, coal combustion ash is considered as potential alternative sources for REY. Understanding the content, speciation, retention and/or transformation behavior of REY during coal combustion not only expands our knowledge of the combustion behavior of the trace elements in coal, but also provides basis for modeling REY partitioning during coal combustion and for developing economically viable REY recovery technologies.
