Fixed bed pyrolysis of the rapeseed cake

The fixed bed atmospheric pressure pyrolysis and nitrogen swept pyrolysis of the rapeseed cake obtained from cold extraction press have been investigated. Experiments were performed in the Heinze retort at a 7 degrees C min(-1) heating rate, with a 500 degrees C final temperature varying sweep gas velocity (50, 100, 150, 200, 250, 300 cm(3) min(-1)) under nitrogen atmosphere. Liquid, gas, and char yields were determined, pyrolysis conversion was calculated, and liquid, char, and gas products were presented as an environmentally friendly fuel candidate.
