Lignin is a macromolecule formed from three precursors p-hydroxy-cinnamic-alcohols. This substance is present in the cellulosic pulp and decreases its whiteness. Therefore, it must be removed by delignifying agents in the bleaching process of the cellulosic pulp. Since the use of oxygen as a delignifying agent of cellulosic pulp, researchers have proposed mathematical models to describe the phenomenon of delignification. The literature on mathematical modeling of the oxygen delignificationdoi:10.21577/1984-6835.20180095 fatcat:pxhrtxzwd5gkdpgc3f44fm54ay
