摘要：

The transport and reaction characteristics of the product layer formation process in flue gas desulfurization were investigated theoretically and experimentally. The transport and reaction processes were described by the Thiele number incorporating the influence of the chemical reaction resistance and the diffusion resistance. The results show that the conversion rate at the end of the process decreased with increasing Thiele number and increased with increasing temperature and porosity. The conversion rate also depends on the pore geometry and pore size distribution. (C) 2003 Editions scientifiques et medicales Elsevier SAS. All rights reserved.
