| Sumario: | In the present work, biochar composites were produced with multiwall carbon nanotubes, MWCNT’s. The composites were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and surface area analysis (BET) techniques to evaluate the effect of the modifications on the adsorption capacity of CO2. The objective of this work is to obtain a biochar-based composite with a CO2 adsorption capacity 10% higher than that of unmodified biochar (72.6 mg/g). This was achieved by obtaining the biochar from mango peel, orange peel and corn husk by slow pyrolysis and modifying said biochar with MWNCTs by physisorption and ultrasonic cavitation. The purpose of this project consisted of the modification of biochar increases the capacity to adsorb CO2 by at least 10%, which was corroborated by being subjected to a CO2 chamber and verifying its adsorption with a CO2 atmosphere meter. In conclusion, it can be mentioned that the adsorption capacity of corn husk biochar modified with multi-wall carbon nanotubes (BH-MWCNT's) increased by 123% for carbon dioxide. |
