High-Temperature HCl Removal with Sorbents in a Fixed-Bed Reactor

摘要: The HCl removal with sorbents was studied in a fixed-bed reactor at 550 °C. distribution of chlorine the fixed bed shows that upstream end nearly saturated whereas downstream contained less than 2 wt %, and mass-transfer zone is about 6 cm. reaction kinetics two indicates there are critical times which rate controlling steps begin to change. In each rate-controlling experimental results model predictions good agreement. also imply that, as proceeds, pore diffusion inside particle becomes more difficult, thus lowering overall rate.
