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. Two tasks were active during this quarter: Task, Procurement, Construction and Debugging of the Electrochemical Reactors and Particulate Removal System and Task, Electrocatalyst Preparation and Screening Studies. In Task a nine element particulate control apparatus is ready for testing with oxide ion conducting pieces and a test apparatus has been setup to test ceramic oxygen ion conducting electrolyte reactor elements. Task 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 using a series of electrocatalysts in gases containing NO, SO{sub 2} and oxygen. 1 ref., 3 tabs.
