Universidad de Zaragoza Energy and exergy analyses of sewage sludge thermochemical treatment 2018 Access copy available to the general public Unrestricted The aim of this research was to provide a methodology for calculating the energy and exergy balances for the thermochemical treatment of sewage sludge. The results of the balances were assessed and compared for three different scenarios (torrefaction, pyrolysis and pyrolysis combined with catalytic post-treatment of the vapors). The balances were calculated based on previously published experimental data and evaluated under different conditions. The results indicated that the endothermicity decreased with the severity of the process. The energy recovery from the products favored the exothermicity of the processes. The three-step process (pyrolysis of torrefied sewage sludge combined with catalytic post-treatment of the hot vapors) was the least exergy efficient scenario. info:eu-repo/grantAgreement/ES/DGA-ESF/GPT Group-T36 info:eu-repo/grantAgreement/ES/MINECO-FEDER/CTQ2013-47260-R info:eu-repo/grantAgreement/ES/MINECO-FEDER/CTQ2016-76419-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 5.537 2018 THERMODYNAMICS 3 / 60 = 0.05 2018 Q1 T1 ENERGY & FUELS 15 / 103 = 0.146 2018 Q1 T1 2.048 2018 Building and Construction 2018 Q1 Civil and Structural Engineering 2018 Q1 Electrical and Electronic Engineering 2018 Q1 Pollution 2018 Q1 Industrial and Manufacturing Engineering 2018 Q1 Mechanical Engineering 2018 Q1 Energy (miscellaneous) 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0003-4493-6540 Ábrego, J.
