New insight about the relationship between the main characteristics of precursor materials and activated carbon properties using multivariate analysis

Abstract: Agro‐industrial wastes are used as carbon precursors in the production of activated carbon because they are rich in lignocellulosic materials. This study aimed to investigate the relationship between the main characteristics of precursor materials and activated carbons by multivariate analysis. After characterization of the precursor materials and their respective carbons, the principal component analysis and canonical correlation analysis were performed. Materials with cellulose/lignin ratio > 3.0 led to t… Show more

“…It is also a material with a high mechanical strength and high chemical stability, considered a non-graphitic material because its carbon atoms are arranged in a two-dimensional hexagonal structure. However, activated carbon is not a truly amorphous material, due to the presence of a microcrystalline structure that differs from the structure of graphite [ 103 ].…”

“…Agro-industrial residues, such as bark and pits, have high concentrations of cellulose, lignin, and hemicellulose in their composition, which can be converted into commercial products with high added value, although they are often discarded into the environment. In the last decade, research has focused on the synthesis of activated carbon from various agro-industrial by-products, with special attention to those produced from the reuse of lignocellulosic residues (biomass), thus generating materials with low production costs [ 103 ].…”

“…From the standardized data the variance and covariance matrix was obtained, which was factored into a diagonal matrix (Santos et al, 2020). The number of main components (CP) was chosen by assessing the cumulative variance which considers the sum of eigenvalues greater than 70%.…”

“…The contribution of cellulose on char porosity was proven by Xin et al as well . Based on H 3 PO 4 activation on 14 kinds of agroindustrial wastes, Santos et al found that materials with cellulose/lignin ratio >3.0 led to the production of carbons with higher pore volumes and surface areas . Therefore, it is critically important to understand the role of cellulose and lignin in the pore structure development during pyrolysis and activation processes.…”
