Figure 2

Evolution of cross-sectional area (CSA) and normalized average pixel value (APV) of untreated biomass beds by feedstock and peak pyrolysis temperature. APV of the biomass bed is temporally normalised by that of the cell void space. Samples were pyrolysed by a 3 L min−1 stream of pre-heated argon at a rate of 6 °C min−1, followed by a 30-min hold time at peak temperature. Vertical lines indicate the start and end of the 30-min hold time. (a) CSA. (b) d(CSA)/dt. (c) APV. (d) d(APV)/dt.
