Cross-flow, filter-sorbent catalyst for particulate, SO sub 2 and NO sub x control
The objective of this program is to successfully carry out the experiment and design tasks described herein that will lead to the development a single-unit, cross flow filter-sorbent-catalyst. In the first stage of work we will investigate the SO{sub 2} removal and NO{sub x} reduction characteristics of different sorbent-catalyst compositions (in granular form), and we will conduct exploratory tests of cross-flow filters under conditions similar to those found in the combustion gases of small-scale combustors. In the second stage of the program, we will investigate the pollutant control characteristics of prototype filter-catalyst devices. The SO{sub 2} removal and NO{sub x} reduction efficiency of a unit-element' prototype will be investigated. This unit element' will be a slot reactor comprised of two flat porous walls, or slabs' of filter-sorbent-catalyst material separated by a 0.5 centimeter gap. The particulate collection efficiency and back-flushing requirements of a multi-element version of this device will be tested. A sorbent regeneration scheme will also be investigated. The sorbents under evaluation are: CuO, CeO{sub 2}, CuO-Al{sub 2}O{sub 3}, CeO{sub 2}-Al{sub 2}O{sub 3}, CuO-CeO{sub 2}, and CuO-CeO{sub 2}-Al{sub 2}O{sub 3}. Progress is described. 25 refs., 4 figs., 5 tabs.
