Abstract

In an attempt to curb the reduction of anthropogenic CO2 emissions, several CO2 capture technologies have been studied in recent years. This project will incorporate the use of solid adsorption technology in CO2 capture, for this, alternative adsorbents, such as a mixture of Porous Carbonaceous Materials (PCMs) from biomass residues and Hexagonal Boron Nitride (h-BN), will be studied. h-BN has been considered a very promising adsorbent with excellent adsorption capabilities. To improve performance in CO2 capture, heteroatoms have been introduced into the BN structure. In this project, the capture of CO2 in nanomaterials (nanosheets) of BN (BNNS) doped with Fluorine (F) and activated carbon (AC) from a mixture of agricultural residues from passion fruit and guava peel will be studied. A detailed analysis of the pores, as well as textural parameters, specific surface area, pore volume and pore size, will be performed in a porosimeter using the BET and BJH methodology, via N2 sorption. The CO2 capture analyzes will be conducted in a thermogravimetric analyzer. Life Cycle Assessment (LCA) will also be applied on a laboratory scale to measure the possible environmental impacts in the production of AC and BNNS, and simulate scenarios of environmental improvements.
