Two sets of pillared clays (PILCs), chromia and tin-oxide-pillared montmorillonites and laponites, were successfully prepared at Aston University using both conventional and microwave-assisted methods and characterised by X-ray diffraction and thermogravimetric analysis. Microwave irradiation enabled the preparation of the PILCs in a fraction of time of the conventional methods. X-ray powder diffraction...
Analyses of solid streams from a pilot-scale coal gasifier equipped with hot-gas filtration at 580 o C have indicated that all coal-derived mercury was carried away by the fuel gas. Calculations using a thermodynamic equilibrium model have confirmed that there was little potential for removal of mercury in the hot gas filter at these temperatures. In this work, several experimental capture/recovery...
