Valorization of old corrugated container to dissolving pulp

As an alternative raw material for various cellulose derivatives, the current research studied processing of old corrugated container (OCC) in subsequent stages homogenization (soda cooking) and purification (bleaching with hypochlorite). The properties were characterized four different categories including chemical composition or purity, accessibility, reactivity, structural features. Alkali delignification a bleaching sequence HEHEHEA selected pulp followed by characterization properties. dissolving exhibited following properties: yield, 78%; cellulose, hemicellulose, lignin content, 90.5%, 7.76%, 0.3%, respectively; alpha 70%. Pulp reactivity measured two experiments showed Fock value 85.67% as well iodine sorption (ISV) 94.95 g/g; accessibility represented tests water retention (WRV) alkali capacity (ARC) 6.87 first 6.1% latter, degree polymerization (DP), 913.4; crystallinity index, 76.95%; brightness, 72.87%. FTIR spectroscopy Brunauer-Emmet-Teller (BET) isotherms utilized to examine modifications OCC pulp. results indicated that produced from is suitable DP applications derivatives.
