The IGR Process emission control technology controls SO{sub 2}/NO{sub x}, and particulate emissions from coal combustion flue gases. The technology uses an electrochemical solid-state reactor which converts SO{sub 2} and NO{sub x} to S, N{sub 2}, and O{sub 2}. The cell electrolyte is a solid electrolyte, namely a high surface area ceramic oxide-ion conductor. Tasks this quarter include: (1) Procurement, Construction and Debugging of the Electrochemical Reactors and Particulate Removal System; (2) Reactor Operation on SO{sub 2}/NO{sub x} Spiked Gas Streams; and (3) Electrocatalysts Preparation and Screening Studies. In Task (1) the particulate control test apparatus has been completely installed and flyash tests have begun. During the tests a voltage is applied across the solid electrolyte and the current is monitored while flyash passes through the cell. In Task (1) electrochemical measurements were made with oxide ion conducting ceramic disks in gases containing NO and SO{sub 2}. In Task (3) the electrochemical measurements are being made using four electrocatalysts in gases containing NO, SO{sub 2}, and oxygen. 3 refs., 4 figs., 2 tabs.
