In this paper, the authors propose a method for analyzing mercury oxidation catalyst results in a kinetic framework using the bulk reaction rate for oxidized mercury formation normalized by either the catalyst mass or surface area. Four mercury oxidation catalysts were tested in a packed bed reactor in the presence of flue gas generated by the NETL 500 lb/h coal combustor: Ir, Ir/HCl, Darco FGD activated carbon, and Thief/HCl. The catalyst-normalized results allow for more quantitative analysis of mercury oxidation catalyst data and a model that will allow for efficient scaling up from laboratory-scale to larger-scale studies.
