To distinguish the effects of combustion from those of particle segregation we compare the solutions obtained by modeling of solids as, alternatively, monodispersed or polydispersed particles; and as reactive or inert ones. Results reveal that the preferential motion of the smaller particles towards the bed top significantly delays char consumption at the bottom layers, favors volatile oxidation, and results in a more uneven lateral distribution of the off-gas. info:eu-repo/grantAgreement/ES/MINECO/CSD2010-00011 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 7.033 2020 CHEMISTRY, APPLIED 8 / 74 = 0.108 2020 Q1 T1 ENGINEERING, CHEMICAL 18 / 143 = 0.126 2020 Q1 T1 ENERGY & FUELS 24 / 114 = 0.211 2020 Q1 T1 1.497 2020 Chemical Engineering (miscellaneous) 2020 Q1 Fuel Technology 2020 Q1 Energy Engineering and Power Technology 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Sánchez-Insa, Alberto Fueyo, Norberto Universidad de Zaragoza (orcid)0000-0001-6205-5160 5001 600 Universidad de Zaragoza Dpto.
