| چکیده | ||
| این مطالعه، به منظوراستفاده از پیت باگاس برای تولید انرژی حرارتی و کربن فعال انجام شده است. برای ارزیابی تولید انرژی، درصد رطوبت، خاکستر، مواد فرار، کربن ثابت، لیگنین، عناصر، دانسیته حجمی، نقطه ذوب و ارزش حرارتی پیت اندازه‌گیری شد. میانگین خاکستر پیت باگاس 23/30 درصد و مواد فرار آن 14/67 درصد اندازه‌گیری شد. میانگین دانسیته حجمی پودر پیت با مش 80 برابر 15/0 گرم بر سانتیمتر مکعب تعیین شد. میانگین لیگنین و نقطه ذوب این پسماند به ترتیب 1/23 درصد و 1050 درجه سلسیوس تعیین شد. درصد گوگرد که به لحاظ آلایندگی محیط زیست اهمیت دارد، برای پیت باگاس 3/0 درصد تعیین شد. ارزش حرارتی ناخالص اندازه‌گیری شده با بمب کالری‌متری برای MJ/kg 3/10 اندازه‌گیری شد که نسبت به باگاس و چوب کمتر می‌باشد. کربن فعال تهیه شده از پیت باگاس به روش شیمیایی با کلرید روی فعال شد. میانگین سطح آزاد (BET) 478 مترمربع بر گرم و قطر منافذ 45/7 نانومتر بوده که بر این اساس، کربن فعال به دست آمده برای جذب مایعات مناسب‌تر است. آزمون یدومتری نشان داد که میانگین عدد یدی کربن فعال تهیه شده 504 میلی‌گرم بر گرم می‌باشد. | ||

| چکیده [English] | ||
| The purpose of this study is the evaluation of bagasse pith for heating energy and activated carbon production. To assess the energy production of the pith, bulk density, melting point, and heating value were measured. Furthermore, percentage of moisture, ash, volatile compounds, fixed carbon, lignin, and elements contents were determined. Ash and volatile content average were measured at 30.23% and 67.14%, respectively. The bulk density average of the pith powder with 80 meshes was determined at 0.15 g/cm3. Lignin content and melting point of pith is measured 23.1%, and 1050 °C, respectively. Sulfur content is important in terms of environmental pollution and it was determined 0.3%. Gross heating value was measured directly by calorimeter bomb to 10.30 MJ/kg that is lower than bagasse and wood. The activated carbon produced from pyrolysis of bagasse pith was chemically activated with zinc chloride. The chemically activated carbons were characterized by measuring iodine of 504 mg/g, specific surface (BET) of 478 m2/g, and pore diameter of 7.45 nanometer. It is suitable for liquid absorption according to the pore size. | ||
