Abstract
"Biochar (BioC) production from biomass is attractive due to its low cost and relevant physicochemical characteristics. Within this context, the objective of the present work was to produce BioC from cellulose of Pinus elliotti, with different pyrolysis parameters, intended for use in CO2 adsorption from the atmosphere. As main results, the produced BioC presented a porous structure, with a fibrous characteristic, due to the raw material used (cellulose). Also, the biochar prepared at 800 °C (P800) presented higher specific surface area and total pore volume than that prepared at 600 °C (P600), due to the higher pyrolysis temperature applied. On the other hand, P600 presented a higher conversion of cellulose to BioC. Due to these characteristics, P800 presented greater ability to adsorb CO2. Thus, a potential use for BioC was identified in this work."
