Can slow pyrolysis take place in 200 degrees
WebPyrolyzed wood slowly dries out, breaks down chemically, and can combust at a minimum temperature of 200°F compared to regular wood that burns at around 400°F. It can take a very long time for this chemical … WebThe proportion of each pyrolysis product mainly depends on temperature and heating rate. Between 573 and 823 K, fast pyrolysis takes place in a few seconds and results in high oil production levels, whereas slow pyrolysis is characterized by low heating rates and leads to maximum charcoal production (Helsen and Van den Bulck, 2006; Morrell, 2004).
