Research is being conducted to characterize waste materials from advanced coal utilization processes and to develop innovative management practices for coal utilization waste disposal. The purpose is to predict the environmental impacts of wastes from several processes being developed at the University of North Dakota Energy and Mineral Research Center (UNDEMRC). The project is currently evaluating the chemical, physical, and leachate production properties of wastes from an atmospheric fluidized bed combustion (AFBC) process, a low-temperature coal gasification process, and a hot-water-drying coal slurry preparation process. Methods are also being developed for constructing fly ash liners at waste disposal sites, evaluating the use of new leaching tests for coal utilization wastes, and developing statistical procedures for analyzing soils data collected at candidate waste disposal sites. Eleven different waste materials were characterized during this reporting period. Six wastes were characterized from AFBC tests which used a coal slurry fuel. Four wastes were characterized from low-temperature coal gasification runs performed for the Hydrogen Production Project, and one waste was characterized from a coal preparation operation associated with the hot-water-drying coal slurry process. 10 refs., 18 figs., 20 tabs.
