Denitrification and desulfurization of combustion gases. Quarterly technical progress report No. 1, September 18-December 17, 1980

The major effort during the first quarter was on the design, construction and debugging of the apparatus. This effort has been completed ahead of the original schedule. Adequate samples have been procured. Some preliminary experiments were performed on denitrification. A complete thermogravimetric (TG) reactor and a packed-bed (PB) reactor were built. The PB reactor was used to gather some preliminary results on the two-step NO decomposition process, using an iron oxide-fly ash sintered sorbent. The results were compared with the direct NO decomposition on the same sorbent (as a catalyst in this case). The yield of N/sub 2/ in the two-step process was about 10 times higher than that by direct catalyzed splitting. The results are preliminary and further studies are in progress. 3 references, 4 figures.
