| Sumario: | For the purpose of this study, pulp and handseet were produced from common hazelnut (Coryllus avellana L.) wood by using Kraft methods. Chip/solution ratio was chosen as 1/5, cooking temperature was 170°C and time for reaching the maximum temperature was 90 minutes. Screened yield was found best in 20/26 active alkali/sulfidity ratio with 47.59 %. With increased active alkali/sulfi dity ratios, screened yield was decreased. The best beating degree has been identified as the 50 SR°. According to cooking parameters, while NaOH/Na2S ratio was 20/26 %, tearing index, breaking length and burst index were reached to the maximum value of 3.83 mN · m2/g, 43.23 N · m/g and 1.87 kPa · m2/g, respectively. These values were used for selecting the optimum cooking parameters. |
