The long term viability of the gas industry will depend increasingly on the production of synthetic natural gas (SNG) from the gasification of coal. Coal gasification produces a number of solid wastes, of which the major type is ash. The ash results directly from the gasification process and from the supporting combustion units that produce steam and electricity for the gasifier. The bulk of the ash is produced by gasification. Disposal of this ash can be an environmental problem, firstly because it contains trace amounts of toxic elements and secondly because contact with groundwater can lead to degradation of water quality from dissolution of the more soluble phases in the ash. The expense of environmentally safe disposal would be eliminated if direct utilization of the ash in the fabrication of construction and road building materials were technically and economically attractive. Alternatively, disposal expenses could be mitigated if metals such as iron and aluminum, or valuable trace metals, could be extracted from the ash prior to its disposal. Such utilization and extraction options have been studied for combustion fly ashes but there is a need for studies focused on gasification ash. The research in this project will utilize ashes from various sources, including the ash to be generated by the Great Plains Gasification Plant (GPGP) complex near Beulah, ND, the first commercial coal gasification plant in the United States.
