Factors Affecting Delignification of Oil Palm Empty Fruit Bunch by Microwave-assisted Dilute Acid/Alkali Pretreatment
Microwave-assisted dilute acid/alkali pretreatment is an efficient and rapid method of removing lignin and hemicellulose, however, the optimized parameters for the maximum efficiency have to date not been presented in the literature. The purpose of this study was to determine those conditions by examining the effects of three factors: microwave power, temperature, and time on delignification in...
متن کاملDelignification of Rice Husk and Production of Bioethanol
Lignocellulose is a generic term for describing the main constituents in most plants, namely cellulose, hemicelluloses, and lignin. Lignocellulose is a complex matrix, comprising many different polysaccharides, phenolic polymers and proteins. Cellulose, the major component of cell walls of land plants, is a glucan polysaccharide containing large reservoirs of energy that provide real potential ...
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...
Comparative study of various pretreatment reagents on rice husk and structural changes assessment of the optimized pretreated rice husk.
The performance of alkalis (NaOH and Ca(OH)2) and acids (H2SO4, HCl, H3PO4, CH3COOH, and HNO3) in the pretreatment of rice husk was screened, and a suitable reagent was assessed for subsequent optimization using response surface methodology. From the assessment, HCl that hydrolysed rice husk well was optimized with three parameters (HCl loading, pretreatment duration, and temperature) using Box...
متن کاملcomposition of essential oil from aegle marmelos peel extracted by microwave assisted hydrodistillation and microwave assisted with pretreatment ultrasound
in this research, microwave-assisted hydrodistillation (md) with pretreatment ultrasound (us) 45 and 90 min of essential oils from fresh aegle marmelos peel were used and the results were compared with those obtained by hydrodistillation technique (hd) in terms of extraction yield/efficiency, extraction time, chemical composition and quality of the essential oil. all experiments were performed ...
