Pulp and paper production from avocado wood by using kraft method

In this, paper pulp and test papers were produced from avocado (Persea americana Mill.) wood by using (kraft) method. While determining the cooking conditions, chip, and solution ratio was taken as 1/5, cooking temperature was 170±2 ℃, maxsimum temperature was reached for minutes and cooking time were 75 and 90 minutes. In group 1, the alkaline (AA) 20 was taken as fixed and the sulfide ratios were changed to 4 different cooking processes (20/20, 20/22, 20/24, 20/26). 2. group cooking conditions were kept the same as the conditions in the first group and alkaline (AA) 18 was fixed, and the sulfide ratios were taken as (18/20, 18/22, 18/24, 18/26), respectively. The 3. group cooking conditions were taken as chip/solution ratio of 1/5, cooking temperature of 160±2 ℃, maximum temperature rise of 60 minutes, cooking time 75 minutes. Alkali (AA) ratio was fixed to 20, (20/20, 20/22, 20/24, 20/26) by changing the sulfide ratios of 4 different cooking. 4. group cooking conditions were kept the same as in the third group cooking and alkaline (AA) 18 was fixed (18/20, 18/22. 18/24, 18/26). In total 16 cooking baking made by examining the properties of the paper. Obtained by making 16 different cooking were examined. Chemical analysis result of avocado wood: holocellulose 73,3 %, α-cellulose 55,1 %, lignin 14,9 %, alcohol solubility 5 %, hot water solubility 3 %, cold water solubility 2 % 1 % NaoH solubility 19,8 % ıt was determined as. Fiber morphology results of avocado wood were determined as fiber length 1,06 mm, fiber width 25,8 µm, lumen width 5,52 µm and wall thickness 4,80 µm. The values obtained after the calculations obtained from the fiber properties: Elasticity coefficient was 53,5, felting ratio was 46,4, runkel coefficient was 0,70 and rigidity coefficient was found to be 41,2.
