Simultaneous particulates, NO(sub x), SO(sub x) removal from flue gas by all solid-state electrochemical technology. Technical progress report No. 1, July 15, 1987-October 1, 1987.

摘要

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 NO(sub x) and SO(sub 2) to nitrogen, sulfur, and oxygen cell. The cell electrolyte is a solid-electrolyte, normally a high surface area ceramic oxide-ion conductor. Tasks this quarter include: Project Work Plan and Electrocatalyst Preparation and Screening Studies of electrocatalysts for high oxygen overpotential and low SO(sub 2) and NO(sub x) overpotential. Tests will be conducted with ceramic disks one inch in diameter. The reactor for disk testing has been built and the disks have been acquired. 4 refs., 9 figs.
