Abstract

Paper manufacturing is a very high water use per ton industrial sector. Chemicals and organic and inorganic substances which pass through black solution from raw material during cooking may cause pollution. Generally, NaOH method is used to manufacture paper pulp from cereal straw. Since, sodium increases water salinity in black liquor which was a residue from paper pulp processes and it must be removed. Black liqour treatment increases the time and cost of operations. For these reasons it has become imperative to search for ways to dispose of the black liquor without performing purification. For this purpose, the alkali selected for cooking should not cause salinity to the soil. In order to produce pulp, KOH was used which is a weaker base than NaOH. Because air has bleaching characteristic, KOH-Air cookings were performed. On the other hand, if potassium is used correctly it will be a considerable nutrient for plants. In this study, the black liquor obtained was strong base having mean pH as 12. The optimum pulp manufacturing conditions were temperature, time and KOH ratio were determined as 120°C, 60 min and 18% KOH. It has seen that pulp and paper quality of KOH method compete par with traditional NaOH method pulp and paper using wheat straw.

Özet

Kâğıt üretimi ton başına üretimde oldukça yüksek su kullanımı olan bir endüstriyel alandır. Pişirme sırasında hammaddeden siyah çözeltiye geçen kimyasallar ve organik ve inorganik maddeler kirliliğe neden olabilir. Genellikle, ekin saplarından kâğıt hamuru elde etmek için NaOH metodu kullanılır. Kâğıt hamuru proseslerinden arta kalan sodyum atık sularda tuzluluğa neden olduğundan uzaklaştırılmalıdır. Siyah çözelti arıtma işlemi zaman ve maliyet artışına neden olmaktadır. Bu nedenlerden dolayı siyah çözeltiyi arıtmadan uzaklaştırmanın yollarını aramak önemlidir. Bu amaçla pişirme için seçilen alkali toprakta tuzluluk yapmamalıdır. Kâğıt hamuru üretmek için NaOH’tan zayıf bir alkali olan KOH seçilmiştir. Hava ağartıcı özellikte olduğundan, KOH-Hava pişirmesi yapılmıştır. Eğer potasyum doğru kullanılırsa bitkiler için önemli bir besin kaynağıdır. Bu çalışmada, elde edilen siyah çözelti pH ortalaması 12 olan güçlü bir bazdır. Optimum hamur üretim şartları sıcaklık, zaman ve KOH oranı olarak sırasıyla 120°C, 60 dak. ve %18 KOH olarak tespit edilmiştir. KOH metodu ile elde edilen hamur ve kâğıtların kalitesi geleneksel NaOH metodu ile buğday saplarından üretilen hamur ve kağıtlarla başa baş rekabet edecek seviyede olduğu görülmüştür.
