Simultaneous removal of SO2 and NOx from simulated gas was investigated using a continuously operating fluidized bed reactor with variables of gas velocity, sorbent/catalyst feeding rate, aspect ratio (L/D), temperature, sorbent/catalyst size. NMO (natural manganese ore) was used as a sorbent and catalyst of size from 0.715 mm to 0.194 mm in diameter. Particle size, aspect ratio, and sorbent feeding rate did not affect the reduction of NOx with ammonia, and NOx removal efficiency was about 94% at 350°C, gas velocity of 0.204 m/sec, L/D=1.0. SOx removal efficiency was affected by temperature, gas velocity, sorbent/catalyst feeding rate, aspect ratio and sorbent/catalyst size and it was about 92% at 450°C, gas velocity of 0.204 m/sec, sorbent/catalyst feeding rate of 8.54 g/min, L/D=1.0.
