Interdependent factors influencing the carbon yield, structure, and CO$$_{2}$$ adsorption capacity of lignocellulose-derived carbon fibers using multiple linear regression

Abstract Cellulose has experienced a renaissance as precursor for carbon fibers (CFs). However, cellulose possesses intrinsic challenges substrate such typically low yield. This study examines the interplay of strategies to increase carbonization yield (ligno-) cellulosic manufactured via coagulation process. Using Design Experiments, this article assesses individual and combined effects diammonium hydrogen phosphate (DAP), lignin, CO $$_{2}$$ 2 activation on properties cellulose-based fibers. Synergistic are identified using response surface methodology. paper evidences that DAP lignin could affect pyrolysis positively in terms Nevertheless, do not have an additive effect increasing In fact, can negatively within certain composition range. Further, thermogravimetric adsorption respective CFs was measured, showing relatively high values (ca. 2 mmol/g) at unsaturated pressure conditions. The were microporous materials with potential applications gas separation membranes storage systems. Graphical abstract
