The IGR emission control technology controls SOx, NOx, and particulate emissions from coal combustion flue gases. It is based on a solid-state, flow-through, electrochemical reactor which reduces NOx and SO{sub 2} to nitrogen, sulfur, and oxygen. The cell electrolyte is a solid electrolyte, normally a high surface area ceramic oxide-ion conductor. Three tasks were active during this quarter, Task (1) Development of 10 Cubic Feet/Min High Surface Area Electrochemical Reactors, Task (2) Procurement, Construction and Debugging of the Electrochemical Reactors and Particulate Removal System and Task (3) Electrocatalyst Preparation and Screening Studies. Task (3) is the screening of electrocatalysts for high oxygen overpotential and low SO{sub 2} and NO{sub x} overpotential. Electrochemical measurements were made with oxide ion conducting ceramic disks in nitric oxide and sulfur dioxide gas mixtures. 2 refs., 10 figs.
