Fixed-bed pyrolysis of safflower seed: influence of pyrolysis parameters on product yields and compositions

摘要

Fixed-bed slow pyrolysis experiments have been conducted on a sample of safflower seed to determine particularly the effects of pyrolysis temperature, heating rate, particle size and sweep gas flow rate on the pyrolysis product yields and their chemical compositions. The maximum oil yield of 44/100 was obtained at the final pyrolysis temperature of 500 deg. C, particle size range of +0.425-1.25 mm, with heating rate of 5 deg. C min~-1 and sweep gas (N_2) flow rate of 100 cm~3 min~-1 in a fixed-bed lab-scale reactor.
