Slow fast and flash pyrolysis of rapeseed
Webb24 maj 2024 · Depending on the operating conditions, the pyrolysis process can be divided into three sub-classes: conventional slow, fast and flash pyrolysis (Onay and Kockar 2003 ). Slow pyrolysis is performed at a low heating rate and at longer residence time giving maximum char yield. Webb1 mars 2004 · Fixed-bed slow and fast pyrolysis experiments have been conducted on a sample of rapeseed. The experiments were performed in two different pyrolysis reactors, namely a fixed-bed Heinze and a well-swept fixed-bed tubular retort to investigate the effects of heating rate, pyrolysis temperature, particle size, sweep gas velocity on the …
