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."

纤维素制备生物炭捕获大气co2的特性

“生物炭（BioC）生物质生产由于其低成本和相关的物理化学特性而具有吸引力。在此背景下，本工作的目的是从湿地松的纤维素中生产具有不同热解参数的生物炭，用于从大气中吸附CO2。主要结果是，由于使用的原料（纤维素），生产的BioC呈现出多孔结构，具有纤维特性。此外，由于采用了更高的热解温度，在800°C（P800）下制备的生物炭比在600°C（P600）下的生物炭具有更高的比表面积和总孔体积。另一方面，P600表现出较高的纤维素向BioC的转化率。由于这些特性，P800表现出更大的吸附CO2的能力。因此，在这项工作中确定了BioC的潜在用途。“
