Effect of pressure on char combustion rate, NO emission and limestone H_2S capture reactions was examined by using a pressurized fixed bed reactor. The effect of pressure on the char combustion rate was different in different rate control regimes. The NO emission evidently decreased with increasing pressure. With increasing pressure, the limestone H_2S capture was dominated by reactions as follows: (1) H_2S reaction with CaO, (2) CaCO_3 decomposition and (3) H_2S reaction with CaCO_3.
