AB : Cellulose is the most abundant component of biomass and the one that requires the mostactivation energy (Ea) for pyrolysis. In this study, the dependence of Ea on the intrinsic cellulosecharacteristics, such as the degree of polymerization (DP), crystallinity, and crystal size, was studiedin different cellulose samples, including samples from Eucalyptus globulus, Ulmus minor, Linunusitatissimum, Olea europaea, Robinia pseudoacacia, and Populus alba. Then, to describe the pyrolyticdegradation of cellulose, the Ozawa–Flynn–Wall kinetic method was the most appropriate amongthe isoconversional models studied. An acceptable quadratic relationship of R2 > 0.9 between theEa values of the different cellulose samples with their corresponding DP, crystallinity index, andcrystal size values was found. Therefore, low crystallinity and low-to-medium crystal size values aredesired to obtain lower Ea values for cellulose pyrolysis. On the other hand, DP did not present aclear effect on Ea in the studied DP range
