DEVELOPMENT OF DEPLETED-URANIUM CATALYSTS FOR DESTRUCTION OF AIR POLLUTANTS IN AUTOMOBILE EXHAUST

摘要

During the past year a number of catalysts were tested for oxidation activity in the continuous flow system. Results indicate that some of these preparations used in a properly designed catalytic muffler might meet the specifications of the California Standards for exhaust gas composition. Four of these catalysts, all impregnated on alumina spheres, were active enough to oxidize is pentane from 0.2 percent concentration to below 0.033 percent at 600° C. in the presence of 2 percent carbon monoxide and 4 percent oxygen at an hourly space velocity of 10,000, (which corresponds to a reasonably sized muffler of 1/2 cubic foot volume for an average automobile.)
