There are many factors influencing a pyrolysis process. The main factors discussed in this paper are the
effect of particle size, heating rate and the properties of biomass itself. Smaller OPT size produces 0.04-
0.86% more volatile product when pyrolyzed at both heating rates. EFB on the other hand shows 3.81-
9.81% increment. Heating rates speed up the peak degradation by 1.42-1.56 mg/s at dp1 and 3.13-4.92
mg/s at dp2. 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 (atdp2 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.
