Studies were conducted under a NASA contract funded by DOE to experimentally demonstrate the durability of conclusion ATCOM catalysts and catalyst supports in a combustion environment under simulated gas turbine engine combustor operating conditions. A test of 1000-hours duration was completed with one catalyst using No. 2 diesel fuel and operating at catalytically-supported thermal combustion conditions. This five-atmosphere pressure durability test was conducted using an air-preheat temperature of about 640/sup 0/K and a reference velocity of about 14 meters/second. The adiabatic flame temperature of the fuel/air mixture was 1533/sup 0/K. The performance of the catalyst was determined by monitoring emissions throughout the test, and by examining the physical condition of the catalyst core at the conclusion of the test. Tests were performed periodically to determine changes in cataytic activity of the catalyst core. Detailed parametric studies were also run at the beginning and end of the durability test, using No. 2 fuel oil. Initial and final emissions for the 1000-hours test respectively were: unburned hydrocarbons (C/sub 3/ vppm): 0, 146; carbon monoxide (vppm): 30, 2420; nitrogen oxides (vppm): 5.7, 5.6.
