Studies at our laboratory in the last several years in fossil fuel conversion processes have included work on coal gasification, oil gasification, and fluidized bed combustion. A common aspect of these high temperature processes is the production of potentially large quantities of spent limestone or dolomite. This brief presentation describes the logic of the experimental program and presents results of initial bench-scale tests. It was shown that fluidized bed combustion residues could be processed into 5-cm cubes with compressive strengths to 13.8 MPa (2000 psi). Such residues appear to have potential for use in some sectors of the construction industry.
