A series of drying experiments on municipal solid waste(MSW) in Guangzhou were conducted in air dry oven，simulating the drying process in incineration. The influence of temperature on drying characteristics of MSW was analyzed. Seven different drying models were fitted to the experimental data as comparing the correlation coefficient and chi-squared value. The optimal drying models were obtained to predict experimental drying process. The results showed that drying time was shorter and the maximum drying rate was higher with the higher drying temperature. The drying time decreased from 322min to 102min and the maximum drying rate increased from 0.009g/(g·min) to 0.027g/(g·min) as the drying temperature rising from 100℃ to 160℃. The experimental drying process could be described accurately by page, Modified page and Weibull distribution models. The effective diffusivity of MSW changed from 2.212×10-9m2/s to 8.044×10-9m2/s with fick’s diffusivity model. The MSW activation energy of 27.035kJ/mol was determined through Arrhenius equation.
