Ethylene Glycol/soda Organosolv Pulping of Olive Tree Trimmings
This paper reports on the influence of independent variables in the ethylene glycol/soda pulping of olive wood trimmings [viz. cooking temperature (165–195°C) and time (30–90 min), ethylene glycol concentration (5–15%), soda concentration (2.5–7.5%), and liquid/solid ratio (4/1–6/1)], on the yield and viscosity and holocellulose, -cellulose, and lignin contents of the pulps. By using a central ...
متن کاملStudy on organosolv pulping methods of oil palm biomass
Comparative study on organosolv pulping method have been done by using various mixtures of water and organic solvents as delignifying agents including ethylene glycol-water mixtures, ethanol-water mixtures and acetic acid-water mixtures to extract cellulose from agricultural crop biomass (Oil palm empty-fruit bunches-OPFB). The yield of organosolv pulping with ethylene glycol-water mixture, eth...

تعارفات کنش های گفتاری هستند که افراد در زندگی روزمر? خود به منظور برقراری دوستی یا تداوم روابط مسالمت آمیز به کار می برند. ساز و کار تعارف مختص زبان انگلیسی یا هر زبان دیگری نیست و پدیده ای است جهانی و در همه زبانها حضور دارد. تفاوتی که از این نظر در زبانها و فرهنگ ها وجود دارد مربوط به پاسخ به این کنش گفتاری در گفتمان است. این مطالعه به بررسی تنوع پاسخ های انگلیسی و عربی به کنش گفتاری تعارف د...
Optimization of Ecf Bleaching and Refining of Kraft Pulping from Olive Tree Pruning
The aim of the present work was to find an optimum kraft pulping process for olive tree pruning (OTP) in order to produce a bleachable grade pulp of Kappa number about 17. The kraft pulp produced under optimized conditions showed a viscosity of 31.5 mPa.s and good physical, mechanical, and optical properties, which are acceptable for paper grade production. The strength and optical properties w...
