英文摘要To simulate the drying behavior of lignite in the high-temperature thermal conversion process, a micro fluidized bed reactor was adopted to measure the drying characteristics of moist char from 773 K to 1173 K and calculate the drying kinetics. Both temperature and the initial moisture strongly affected the drying behavior by changing the curve shape and drying time. The higher the initial moisture, the more obvious the influence of drying temperature. Compared to the conventional low-temperature lignite drying, the rate curve tested by MFBRA only had the growing-rate zone and falling-rate zone, but did not include the common constant-rate zone. Under the experimental condition, the Lewis drying model can describe the drying characteristics of wet char in MFBRA very well. The apparent diffusion coefficient and activation energy ranged from 1.765 E -10 to 4.756 E -10 m(2)/s, and 12.83-14.97 kJ/mol, respectively. The activation energy was much lower than those in literature.
