Influence of the pulping and TCF bleaching operating conditions on the properties of pulp and paper obtained from olive tree residues

摘要: The paper discusses the influence of operating conditions (hydrogen peroxide concentration - 1 to 3%, sodium hydroxide process temperature 90 110 °C) applied in oxygen and ozone (ozone 0.2 0.4%) bleaching olive wood trimmings pulp on properties bleached pulps (kappa number, brightness viscosity). A second central composite factor design was used derive equations that relate dependent variables considered bleaching. High (3%) (0.4%), intermediate or low values hydrogen (1-2%) (90-100 were required for suitable TCF pulp. comparison two (i.e., with without peroxide) selected sequences revealed similar at higher kappa viscosity values.
