The report discusses recent work addressing lime enhancement by slurrying with siliceous materials and testing in a laboratory packed-bed reactor, as part of EPA's efforts to develop low cost, retrofit flue gas cleaning technology, including the development of highly reactive sorbents. The solids generated from a furnace limestone injection process were reactivated by slurrying at elevated temperatures. Compared with untreated solids, reactivity toward SO2 was significantly enhanced by hydration. The SO2 capture by solids increased with increasing time and temperature of hydration. The dry sorbents produced by slurrying several diatomaceous earths, or montmorillonitic clays, with lime were found to be highly reactive with SO2. The most reactive sorbent was generated by slurrying silica/lime at a weight ratio of 1 to 1. The morphology of the developed sorbents was characterized. Several additives were tested to evaluate their potential to promote the lime/silica reaction rate and increase sorbent reactivity.
