Pyrolysis experiments of hazelnut shells were conducted by tube furnace pyrolysis reactor at 400-1,000 degrees C. The results indicated that the effect of pyrolysis temperature on yield and characteristics of bio-char was significant. With the deepening of carbonization, bio-char yields decreased, approximately 50 wt% of VM were released, and the concentration of FC increased by 47 wt%. The optimum for HHV (33.3 MJ/kg) and combustion reactivity was at 900 degrees C and 700 degrees C, respectively; the adsorption capacity of bio-char was optimal and was determined by BET surface area and iodine absorption value (respectively 197.3 m(2)/g and 595.4 mg/g) at 800 degrees C. The results provided a strong support for bio-char application from discarded hazelnut shell pyrolysis.
