The performance of a catalytic reactor 12 cm in diameter and 17 cm long was evaluated at sim¬ulated gas turbine combustor operating conditions using premixed propane and air. Inlet tem¬peratures of 600 and 800 K, pressures of 3 and 6 atm, and reference velocities of 9 to 30 m/s were tested. Data were taken for equivalence ratios as high as 0.43. The operating range was limited on the low-temperature side by very poor efficiency;the minimum exit temperature for good performance ranged from 1400 to 1600 K depending on inlet conditions. As exit tempera¬tures were raised above this minimum, emissions of unburned hydrocarbons decreased to less than 4x10-3 g CH2.67/kg fuel, carbon monoxide emissions became generally less than 1 g CO/kg fuel, and nitrogen oxides were less than about 0.1 g NO2/kg fuel.
