Özet
Aim of study: This study was carried out to evaluate canola (Brassica napus L.) stalks as an alternative raw material for pulp and paper production. Area of study: This work was carried out in Kahramanmaras Sutcu Imam University, Faculty of Forestry, Pulp and Paper Production Laboratory. Material and Methods: Before pulping procedure, the chemical components of the canola stalks were investigated. The holocellulose, alpha cellulose, lignin, and ash contents and NaOH (1%) and cold-hot water solubilities were determined. Modified kraft cooking method was used for pulping from canola stalk by using sodium borohydride (NaBH4). Sulfidity charge; 26, 28, 30%, and NaBH4 charge; 0, 0.1, 0.3, 0.5% were changed while keeping constant temperature (150 degrees C), time (120 min) and alkali charge (20%). For determination of the optimum pulping condition, 12 cooking experiments were performed to canola stalks. In addition, the physical and optical properties of the papers produced from the obtained pulps were also determined. Main results: The holocellulose (72.10%) and lignin (13.15%) contents of the canola stalks were found to be similar with hardwoods. The optimum cooking condition was determined as 20% active alkali, 28% sulfidity and 0.5% NaBH4 charges (as NaOH) and the total pulp yield were obtained about 44.7% in this condition. Besides, the addition of NaBH4 increased pulp yield by 24.1% and decreased kappa number by 9.7%. Research highlights: It was concluded that obtained results demonstrate the suitability of canola stalk for pulp and paper production and NaBH4 is an effective cooking additive for the pulp yield.
