- Abstract
- In this work we have developed a regenerable synthetic sorbent based on manganese oxides (12% w/w)
impregnated on high surface area c-alumina and supported as a thin layer (40 lm) onto cordierite honeycomb
monoliths (400 cpsi). Such structured sorbents are well suited for flow-through exhaust gas
treatment associated with very low pressure drop. Elemental mercury capture experiments were carried
out in a lab-scale quartz reactor in air at temperatures ranging from 50 to 350 ?C, Hg concentration in the
range 50-250 lg/m3, GHSV = 3.6 ? 105 h?1. A kinetic and capacity characterization of the sorbent was
conducted, giving insight on the controlling mechanisms of the mercury capture process. Structured
MnOx sorbent performed satisfactorily up to 300 ?C, the performance decaying dramatically above this
temperature when desorption of elemental Hg became predominant. TPD experiments after mercury
uptake on the sorbent, showed that the sorbent could be completely regenerated at a temperature as
low as 500 ?C. Repeated cycles of mercury adsorption/desorption did not lead to any significant reduction
of the sorbent capacity towards mercury uptake. No significant mercury oxidation in the gas phase was
observed under the operating conditions used in the experiments. (literal)
