摘要：采用N_2-CO_2气体稳态法测定了表面中毒C207催化剂的扩散通量,应用平行交联孔模型求得催化剂的曲节因子,按平均孔径计算的曲节因子δ_F:未中毒催化剂3.65,中毒催化剂2.99至3.11;按孔径分布计算的曲节因子δ:未中毒催化剂4.17,中毒催化剂3.45至3.71。
The diffuse fluxes have been measured by using the steady state method, nitrogen and carbon dioxide are used for diffusion gas pair. The tortuositdy factors of non-poisoned and surface poisoned C207 catalyst are obtained. The values of tortuosity factor are 3.65 for non-poisoned catalyst and from 2.99 to 3. 11 for surface poisoned catalyst according to average pore size, 4.17 for non-poisoned catalyst and from 3. 45 to 3.71 for surface poisoned catalyst according to pore size distribution.
