investigation of chemical pretreatment of rice straw with ammonia, urea and sodium hydroxide
agricultural residues have high potential to produce biogas, but they contain lignocellulosicmaterials which are not easily degradable, so the pretreatment is required. chemical pretreatmentincreases the rate of degradation and efficiency of biogas production. this study has beeninvestigated the effect of 4% -urea, 5%-ammonia and 8%-sodium hydroxide on degradation of ricestraw and production of...
متن کاملUtilization of Urea and Urease Treated Rice Straw by Indigenous Growing Cattle
The experiment was conducted to study the effect of treatment of rice straw with urea and a urease containing midden soil on the chemical composition of treated rice straw, feed intake of the animals, nutrients digestibility, body weight gain, feed conversion efficiency and overall economy of feeding for a period of 105 days. Twelve indigenous growing cattle (live weight 130.00±1.67 kg) were se...
متن کاملchemical recycling of polycarbonate waste using conventional heating and microwave assisted method
پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
Enhanced Surface Wettability of Rice Straw with Alkaline Pretreatment
To improve the surface wetting properties of rice straw, effects of distilled water and four alkali pretreatment on the straw surface wettability were analyzed. The straw surface contact angle at different time points was measured by JC2000A contact angle measuring apparatus, optical microscope (OM) and scanning electron microscopy (SEM) combined with a linear regression technique for parameter...
متن کاملEvaluation of High Solids Alkaline Pretreatment of Rice Straw
Fresh-harvested, air-dried rice straw was pretreated at a water content of 5 g H(2)O/g straw using sodium hydroxide (NaOH) and compared to pretreatment at 10 g H(2)O/g straw by hydrated lime (Ca(OH)(2)). Full factorial experiments including parallel wash-only treatments were completed with both sources of alkali. The experiments were designed to measure the effects of alkaline loading and pretr...
