The production and evaluation of bio-oils from the pyrolysis of sunflower-oil cake


, : The production and evaluation of bio-oils from the pyrolysis of sunflower-oil cake. Biomass and Bioenergy 23(4): 307-314

Sunflower (Helianthus annus)-oil cake pyrolysis experiments were achieved in a fixed-bed tubular reactor. The effects of nitrogen flow rate and final pyrolysis temperature on the pyrolysis product yields and chemical compositions have been investigated. The maximum bio-oil yield of 48.69 wt% was obtained in nitrogen atmosphere with nitrogen flow rate of 100 cm3 minute-1 and at a pyrolysis temperature of 550 degrees C with a heating rate of 5 degrees C second-1.
