摘要：

Percolation theory is improved and applied to analyze the catalytic effect of NaCl addi-tive on desu1phtirisation with limestones under the Fluidized Bed(FB) conditions. The autherproposed that NaCl not only enlarges the average inner pore diameter but also improves thepore connectivity of CaO calcined by limestone, which can be proved by the changing ofBethe network coordination number(Z) from 6 without NaCl to 7.8 when NaCl is presentwith a content of 1.95 wt%.
