Abstract
Poultry litter waste (PLW) is the main by-product generated by the Brazilian poultry industry. A sustainable approach for reusing this waste is the production of biochar to be further used aiming CO2 adsorption. In this work, biochars were produced by varying the N2 flow along the pyrolysis process of 150 (PLW-150) and 1000 (PLW-1000) mL min -1. PLW and biochars were characterized for their morphology, porosity, specific surface area, and CO2 adsorption capacity. From the biochars, carbon cryogels (CC) were produced aiming their use as CO2 adsorbents. The results of the cryogel adsorption test showed a CO2 adsorption capacity of 13.1±2.9 and 33.8±3.3 mg g -1 for the CC-PLW.150 and CC-PLW.1000 cryogels, respectively. Therefore, reusing this residue for cryogels production and its use in the CO2 adsorption signifies an attractive perspective to minimize the environmental damage caused by CO2 emissions.
家禽垃圾(PLW)是巴西家禽业产生的主要副产品。一种可持续的方法是生产生物炭，进一步用于二氧化碳吸附。在这项工作中，通过在150 (PLW-150)和1000 (PLW-1000) mL min -1的热解过程中改变N2流量来生产生物炭。对PLW和生物炭的形貌、孔隙度、比表面积和CO2吸附能力进行了表征。从这些生物炭中，制备了碳冷冻剂(CC)，目的是将其用作二氧化碳吸附剂。低温凝胶吸附实验结果表明，CC-PLW的CO2吸附量分别为13.1±2.9和33.8±3.3 mg g -1。150和CC-PLW。分别是1000个冰镇。因此，将这些残渣用于冷冻产品的生产和二氧化碳的吸附是一个很有吸引力的前景，可以最大限度地减少二氧化碳排放对环境造成的破坏。
