Chars were produced through slow pyrolysis at different peak temperatures (350 and 500 °C), pressures (0.1 and 0.5 MPa), and residence times of the vapor phase (50 and 150 s). From the thermogravimetric curves obtained under air, the combustion performance index (S) was calculated for each char. Apparent kinetics were also estimated using the Coats–Redfern method and assuming an F3/2 reaction model. Results show that the combustion patterns of chars were more influenced by the type of feedstock than by the pyrolysis conditions. Corn stover appeared to be the most interesting feedstock in order to produce chars with tuned reactivity. Results from partial least-squares (PLS) regression revealed that the most important factors affecting S were the contents of potassium (negative effect) and cellulose (positive effect) in the original biomass. info:eu-repo/grantAgreement/ES/DGA-FEDER/T22-17R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.654 2021 ENGINEERING, CHEMICAL 45 / 142 = 0.317 2021 Q2 T1 ENERGY & FUELS 63 / 119 = 0.529 2021 Q3 T2 0.822 2021 Chemical Engineering (miscellaneous) 2021 Q1 Energy Engineering and Power Technology 2021 Q1 6.3 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Alvira, D.
