For this purpose, two biomasses (vine shoots -VS and corn stover -CS) were pyrolyzed at different temperatures (350 and 500 °C) under different pressures (0.1 and 0.5 MPa) for a residence time of 60 min. Agronomic properties of biochars (including stability, pH, CEC, EC, bulk density, surface properties, and water holding capacity) were determined. Pyrolysis temperature impacted greatly on the biochar stability and the textural properties. The dependence of other properties of biochars on pressure and temperature varied as a function of the type of feedstock. In addition, the effects of pyrolysis temperature and pressure on 16 US EPA PAH concentration in biochar were also investigated. The PAH concentrations ranged between 0.822 and 5.112 mg kg−1. On average, VS-derived biochar had higher PAH concentrations than CS-derived one. The structural differences in biomass played a key role in determining the effect of pyrolysis conditions on total PAH concentration. info:eu-repo/grantAgreement/ES/MCIU-ERANET-MED/PCIN-2017-048/MEDWASTE info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.8 2023 CHEMISTRY, ANALYTICAL 10 / 106 = 0.094 2023 Q1 T1 ENGINEERING, CHEMICAL 29 / 170 = 0.171 2023 Q1 T1 ENERGY & FUELS 58 / 171 = 0.339 2023 Q2 T2 1.146 2023 Fuel Technology 2023 Q1 Analytical Chemistry 2023 Q1 9.1 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Videgain, María Universidad de Zaragoza (orcid)0000-0002-3630-7931 Manyà, Joan J.
