| Abstract | ||
| The main objective of the present work is to investigate the feasibility of using a slurry of fine activated carbon particles, dp<1mm, in a fixed bed reactor for the removal of sulfur dioxide from simulated flue gas (air, SO2) stream. A mathematical model governing the desulfurization process was proposed. The partial differential equations which describe the adsorption of SO2 from a moving gas stream to the sorbent bed were solved using a finite difference method. The kinetic parameters of the mathematical model were obtained from a series of experimental desulfurization runs carried out at isothermal conditions and different operating conditions; bed temperature (333K-373K), initial SO2 concentration (500ppm-2000ppm) and static bed height (10cm-24cm). The results showed that the use of fine activated carbon particles improved the removal efficiency to about 97%. The verification of the simulation and experimental results showed that the proposed model gave a good description of the desulfurization process with 95% confidence level | ||
