It also causes biomass to be degraded under a narrow temperature range by 21°C. High lignin content in EFB lowers the amount of volatiles produces which is in accordance to literature findings. The peak degradation rate of OPT is also much higher than OPT which is 9.79 mg/s compared to 4.86 mg/s (at dp2 and heating rate 80°C/min). It can be concluded that OPT is more suitable to be used as fast pyrolysis feedstock because it degrades faster and produces more volatiles.
