This final project report summarizes the results of extensive thermodynamic and preliminary experimental studies that have identified the use of aluminosilicate materials for simultaneously removing volatile alkali and particulate released during pressurized gasification of coal. The gettering capacity of three selected materials has been evaluated in a bench-scale reactor operating at 1114 kPa total pressure and 1123 to 1173 K in alkali-laden inert and simulated fuel gas environments. At 1123 K alkali gettering results through insoluble complexes, while at 1173 K saturation of the insoluble complex is completed, with gettering occurring mainly through soluble complexes. The gettering mechanism will be delineated through future thermogravimetric studies in a proposed program extension.
