| Popis: | In the present study, combustion of activated carbon particles was conducted using a thermogravimetric (TG) analyzer and a small-scale fluidized bed test bench. The combustion characteristics of activated carbon particles have been analyzed under different process conditions. The three-dimensional diffusion geometry anti-Jander model has been used to describe the combustion of activated carbon. By using the isothermal differential characteristics, activation energy values under different conversion rates have been obtained, which were then compared with the activation energy values obtained from the TG analyzer. The results showed that the two kinds of activation energy values were similar under low conversion rates. On the basis of TG combustion data, the AKTS software was employed to forecast the mass loss curve of activated carbon combustion under the condition of constant temperature. The curve was compared with the mass loss curve obtained from the fluidized bed. Finally, a comparison was drawn between the fluidized bed combustion and TG combustion for similarities and differences. |
