Reaction Kinetics Study of Willow Char Gasification with CO2 Using TG Analysis

X. Meng, W. De Jong, N. Fu & A.H.M. Verkooijen
Gasification kinetics of willow char with CO2 was investigated using thermogravimetric analysis (TGA). Two different types of char samples have been tested. Char one (PYR-Char) was obtained after willow pyrolysis in a TGA at a final temperature of 750 or 850 °C for 20 min. Char two (CFB-Char) was obtained after willow gasification in a 100 kWth circulating fluidized bed (CFB) steam-O2 blown gasifier within the temperature range of 750 to 820 °C with a...
